Neither of existing materials does not have the slightest chance of displacing the good old tree from its pedestal, loved by everyone for its beauty, environmental friendliness and durability, for its ability to store heat. It is used in many types of construction and renovation work, and wooden floors are especially attractive and pleasant. However, over time, such coatings also develop a big drawback - unsightly gaps between the boards. The reason for this is drying out natural material. Not all owners are ready for drastic changes, and they don’t really want to part with a cozy floor, so the question of how to seal the cracks in the floor will always remain relevant. There are several methods, and they are all quite effective, simple, and therefore do not require special skills from the owners.

Causes of the unpleasant phenomenon

If the owners eliminate the cracks, but do not identify the culprits of their formation, then soon the defects that appear will “delight” them again. Therefore, the first necessary step is to discover the causes of the cracks. Several factors can be suspected of “complicity.”

1. Drying due to natural causes. Any type of wood loses weight over time, but the intensity of this process depends only on the species. The exception is boards that are processed in vacuum chambers; changes in geometry are almost not typical for them. Conventional building material, on the contrary, can lose from 5 to 10%, or even more: the numbers depend on the type and initial moisture content.
2. The air in the house is too dry. In this case, the tree will very quickly give up moisture, which means it will decrease in size. Normal conditions “for life” of such coatings are temperature from +18 to +25°, humidity from 40 to 65°.
3. Laying wet material. The optimal relative humidity for raw materials that are being prepared to become floor coverings is in the range of 8-10%. If the wood is damp, then it will have to dry during use, and such conditions lead to the appearance of cracks.
4. Violation of technology. Incorrect installation - poor fastening of the flooring, non-compliance with horizontal joists - the most common reasons loosening, “walking” of boards, their subsidence, and, naturally, deformation.
5. "Living animals" living underground. Rodents - rats and mice - are required to constantly grind down their incisors, so they have to “train” on everything that comes their way. The second reason is hunger, which draws them to heroic deeds. These cracks and holes are the most severe “injuries”.
6. Wrong choice of material. The optimal boards are made from oak and coniferous species. A floor made of beech, cherry, pear, maple or ash will definitely require repairs, since these types are most susceptible to deformation.
7. Extremely high operating load.

The scope of work depends only on the size and number of cracks, so repairs can be either simple or incredibly complex. The most serious damage already requires radical measures - complete replacement floor.

“Treatment” of cracks with folk remedies

Since the problem has been known to people for a long time, quite a lot of ways have been invented to get rid of defects. Before work, you need to thoroughly study each type of removal, and then choose how to seal the cracks in the floor so that you forget about the flaw for a long time.

Paper, paste, copper sulfate

This method has a big advantage - it is cheaper than other “treatment” options, but it is effective. To camouflage irritating cracks in the floor, the following operation is performed:

1. Paper (for example, newspaper) is torn into small pieces, then they are filled with water.
2. While it is soaking, prepare a paste: mix starch (or flour) with warm water, the resulting “jelly” is poured copper sulfate(1:10, where the first is copper sulfate).
3. Squeezed out soaked paper is introduced into this composition, the putty is thoroughly stirred until its consistency becomes homogeneous.
4. After cleaning the gaps from dirt and dust, spread the mixture onto the cracks, then tamp it down and level it.
5. After drying, the surface is lightly sanded with sandpaper and then painted.

Any composition will adhere reliably only in one case - if the cracks are properly cleaned. When dirt cannot be removed, the gaps are widened. Otherwise, the work will be ineffective: cracks in the floor will appear again.

Sawdust and their “companions”

In this case, there are two ways to prepare a saving mixture: glue (PVA for wood or carpentry) with only sawdust and a product in which cement is also added for greater strength. A clean composition for small cracks is done like this:

1. Fine sawdust is poured with boiling water, mixed well, covered and left to swell for an hour or two.
2. Then they add an adhesive composition in such an amount to form a viscous mass.
3. This putty is applied with a spatula, the excess is removed, leveled, and allowed to dry for 2-3 days.
4. The dried surface is sanded.

Gaps in the floor with a width of 3-7 mm require other sawdust - large ones. It’s even better to take a mixture of different factions.

Sawdust with cement

Preparing a super product with cement requires precise proportions, so measure out:

• water (also hot) - 15 parts;
• glue - 2 parts;
• sawdust and cement - 5 parts each.

The technology here is also different:

1. Water is poured into the glue and mixed, then the remaining components are added: first sawdust, then cement.
2. To ensure that the composition has a color similar to the floor covering, add oil paint or dry dye. Let it brew for about 10 minutes.
3. Before sealing the floor cracks, the mixture is slightly heated. This solution takes 2 weeks to dry. It is also treated with abrasives.

This composition is used not only for sealing cracks, the method is used to level the entire surface of a wooden floor.

Sawdust, varnish and/or paint

Here other ingredients, more native and familiar to the floor, become “colleagues” of small chips. This composition can “cure” cracks of any depth and width.

1. Sawdust, thick oil paint and varnish are mixed in a ratio of 4:1:1.
2. If the gaps are small, then the entire composition is poured out at once.
3. When the flaw is quite large, the mixture is applied in layers after a short period of time.

Reiki wedges to help

This method is very common, because it is difficult to argue with the logic of this decision. Thin slats, lubricated with adhesive, are very easy to drive into any cracks, and gaps hidden in this way will cease to be a headache for a long time (forever?). The work is done like this:

1. Wedges are prepared from pine boards. The width of the elements must be 0.5 mm less than the gap.
2. The cracks are cleaned and then widened a little. The gap and the rail are generously lubricated with glue. The wedge is driven in with a rubber mallet or hammer, but then a small board is placed on it.
3. Wait for the adhesive to dry. The part protruding above the surface is removed using a plane. Tiny defects are camouflaged with a mixture of sawdust and glue.
4. The wedge is treated with stain and painted (varnished).

Identical gaps in the floor are very rare, and making wedges for each gap is a small pleasure. Therefore, all holes are adjusted to the same size using a milling cutter. The advantage of this work is the removal of old wood: the fibers on the fresh cut and wedges guarantee a more reliable connection.

Cement and broken glass

This method is suitable for those who have rodents in their floors, who are happy to test even concrete. Therefore, a simple solution is not a panacea; it can quickly turn into a “washcloth”. And in this case, it is best to first cover the seam with broken glass (for example, fragments of rather thin beer bottles), then fill this “anti-personnel ditch” with concrete, and putty on top.

Worthy alternatives to broken glass - dishwashing wire, cut into pieces, store bought mortar, which contains aluminum chips and concrete mortar. They say that Macroflex polyurethane foam belongs to this category, which is unloved by rodents, but such material is not optimal for the cracks between the boards.

Rope, tow, cord

To implement this method, any twine or rope is suitable; the thickness of the cord depends only on the width of the cracks in the floor: it must be larger than the holes. You will also need glue (PVA, wood glue), sawdust and putty. The work proceeds in the following sequence:

1. The cord is generously coated with glue; it is better to immerse it in the composition and leave it in it for a while. Separately prepare a mixture of glue, sawdust and putty.
2. Using a core and a hammer, the cord is deepened into the gap between the boards by 2-4 mm. The remaining space is filled with a homemade mixture, but the gap is filled with a margin, since the mixture will shrink when it dries.
3. After it hardens, the seams are covered with paint to match the floor.

To get rid of small cracks, they use it in almost the same way. plumbing tow, which is also lubricated (moistened) with glue. It is placed in the holes, compacted, and after drying the floor is painted.

The newest alternative is a sealing cord made from polyethylene foam. It doesn’t need glue, leave 4-5 mm on top free space. It is covered with putty, best view- oil-based composition for wood.

Epoxy mixture

This method is considered one of best options dealing with dry boards. The epoxy-cement “mortar” is praised because of the reliability and strength of such a composition.

1. Epoxy glue is mixed with cement in equal proportions. The consistency of this composition should be similar to thick sour cream.
2. Pour it in with a small margin, because it will shrink during the drying process.
3. The last stage is traditional: sanding the floor and painting it.

Not everyone welcomes this type of adhesive composition, which guarantees strong adhesion. The reason is frequent emergencies during operation - its breaking off along with large fragments of boards.

Chipboards, plywood

This is the most original answer to the question of how to seal cracks in the floor. The use of this method is advisable when cracks in wooden floor can't be counted. In this case, “plastering work” will take a lot of time. Therefore the most effective method- laying chipboard sheets or plywood. However, after this radical operation, a new topcoat will be required.

The sheets are attached to liquid nails, self-tapping screws or regular nails. When choosing the last two types of fasteners, holes are first drilled in the material with a slightly smaller diameter than those of self-tapping screws (nails). The reason for this need is possible deformation of the material.

Means - professionals

The construction market now does not know the word “shortage”, so the choice of different compositions is simply huge. Many of them are created specifically to disguise all sorts of imperfections. Therefore, the question of how to seal the cracks in the floor can be asked to the sellers, but it is better to get to know the possible candidates in advance.

Sealants

Their main “vocation” is to make the seams of materials inaccessible to moisture. There are 2 types of sealants suitable for working with wooden floors:

1. Acrylic compositions. Their plus is the ease of washing off hands, ideal Smooth surface, which is obtained after sanding and painting. Cons - inability to withstand temperature changes and relatively large shrinkage. However, these disadvantages for indoor flooring are not too terrible.
2. Silicone sealants are a real salvation for “walking” floors. They have many advantages. This is plasticity that remains after drying, enviable resistance to stress and compression, and good adhesive qualities. But there is a downside: such mixtures are not suitable for coloring. Stores sell compositions of different colors, but it is not a fact that the owners will be able to successfully choose the shade.

The order of work is as follows:

1. The cracks in the floor are cleaned with a vacuum cleaner, washed and dried.
2. The sealant is squeezed into the gap, then leveled with a spatula, gloved fingers or a spatula.
3. All excess is wiped off with a dry cloth.

The operation is simple and straightforward; it also does not require excessive effort. However, the main condition for success is thorough preliminary cleaning of the cracks.

Polyurethane foam

It is recommended to use construction foam only for sealing cracks around the perimeter of the room, and not between the boards. The reasons for disapproval are deformation of the coating under pressure, uneven filling, change in the shade of the foam under the influence of ultraviolet radiation. The whole operation for areas under the baseboards is as follows:

1. The floor is cleared of debris and dust. If the cracks are impressive, then they put thin stripes polystyrene foam
2. The empty space is filled with foam, then they wait for it to dry.
3. The excess is cut off from the seam, and the surface is puttied.

Putty - palliative

This option cannot be considered a reliable replacement for the previous methods, since this composition will eventually begin to crack, crumble, and fall out. The meager range of colors is another drawback. Situations in which the use of these mixtures is justified are the expectation of a quick repair if the floor is planned to be covered. The work is carried out in the following order:

1. Putty is applied to cleaned surfaces with a rubber spatula and pressed into the cracks.
2. After the composition has dried, the seams are smoothed using sandpaper.

To seal cracks, some recommend using parquet putty, since it has greater elasticity and does not crack so easily. If you are planning to lay tiles or laminate flooring soon, then proceed much simpler: seal the cracks with tape.

Putty with glue

This method gives you a chance to seal small cracks on the floor. It is also suitable if unsightly cracks appear on the surface. This operation requires a certain type of putty - dry finishing mixture, intended for drywall. The same PVA acts as glue.

The composition is mixed in small portions so that its consistency resembles the thickness of sour cream. After applying it to the cracks, the putty-glue is immediately sanded, then quickly leveled, since otherwise it will quickly harden, and in this state it will not be possible to perform the operation efficiently.

How to deal with “playful” boards?

This kind of trouble happens for two reasons: an incorrect lag step is to blame, or the wrong boards were chosen - too thin material. There are also two ways out - installing additional logs or installing thicker boards. Both of them are not very attractive, since they involve dismantling the floor covering. Yes, these options are optimal, but there is a simple way - rallying adjacent elements with dowels. It makes it possible to stop the “play” of the tree and eliminate the deflection.

This operation is not so simple, because there are many nuances in it.

1. Correctly drilling holes at an angle is the first problem. It is necessary to ensure that there is a sufficient layer of wood between the fasteners and the lower/upper plane of the boards. The angle of inclination is selected based on the thickness of the material.
2. Diameter of holes for fasteners. It should be at least 0.5 mm larger than the dowels. The remaining gap will be filled with glue (stationery PVA), which cannot be squeezed out. It will promote swelling of the fibers, so the connection will become reliable and super strong.
3. Drill and template. The length of the tool must be maximum, but find suitable option very difficult. There is a possible solution: welding a rod of the same diameter. The template will greatly speed up the work, especially at the “beginning of glorious deeds.”
4. Sprayer for glue. It is made from a tube of diameter suitable for the spout of the bottle. The length of the segment is 20 cm. The tube is sealed at one end, and small holes are made in it, which will not allow the glue to stain everything around.

Dowels soaked in glue are installed in holes also treated with the compound. The connections are left alone until dry. The raised part of the chops is removed with a grinder, and the cut is polished with what is at hand - the same angle grinder, a hand grinder, or a drill with an appropriate attachment, but at low speeds.

The question of how to seal the cracks in the floor can now be considered closed. Since the choice suitable material depends to a large extent on the depth and width of the flaws, then the owners will have to decide: any means will do, and it doesn’t matter at all whether they are popular or purchased. However, the best way out is to unite the sexes. In this case, the cracks will no longer appear, which means you don’t have to be afraid that at one “wonderful” moment all the “good” that was carefully stuffed in will fall out again.

One of the options for transforming a cracked floor can be seen in this video:

Over time, cracks, gaps and crevices appear on a wooden floor due to changes in temperature and humidity. To get rid of them, it is not necessary to completely recoat the coating - you can deal with this problem yourself by covering up the damage with special compounds.

When choosing how to seal cracks in a wooden floor, you need to pay attention to the size of the damage and the type of floor covering.

Possible options:

• wood putty;
• construction foam with polystyrene foam;
• sealant;
• sawdust or paper mixed with an adhesive base;
• sealing with wedges, cord or slats;
• tow;
• sawdust mixed with oil paint;
• wax and oil;
• epoxy glue with cement;
• plywood, OBS boards or chipboards (for significant damage).

Before covering the cracks, the surface should be prepared: clean it of debris, dirt and dust. Additional processing Treating wood with antiseptic agents will protect it from negative factors (fungus, mold, pests) and increase its service life.

Wood putty

Convenient and accessible remedy for repairing damage on wooden surfaces.

Putties vary in type:

• the filler is used for cracks whose size does not exceed 5 mm;
• finishing helps to remove small ones, up to 1 mm.

They can be produced on the basis of solvents or polyester resins or water-based. Solvent-based compounds are better for repairing larger damage.

When purchasing putty, it is advisable to pay attention to the properties of the composition - elastic and water-resistant products are more reliable and will perform their functions longer.

It is best to use putty to repair minor damage or as a prep before laying down plywood sheets.

Operating procedure:

1. Apply the solution to the cleaned surfaces using a narrow rubber spatula and press it into the cracks and crevices.
2. Leave to dry (the specific time for which the putty will dry is indicated on the packaging).
3. Using sandpaper, level the surface.

Construction foam

Usage polyurethane foam will increase soundproofing properties floor covering. It is also used to eliminate joints between the wall and floorboards.

Work order:

Since the product is exposed to sunlight and other external factors is destroyed, we need to protect it. To do this, you can apply several layers of paint to the treated surface or putty.

Sealant

Eliminating cracks with this product is simple and quick - the sealant bottle is equipped with a special nozzle that helps to apply the composition exactly to the problem area.

A good wood sealant should be silicone or acrylic base. Thanks to its liquid consistency, the product fills the entire area of ​​damage without additional stimulation, distributing evenly. The sealant is elastic, so it will adapt to the dimensions of the boards changing from external conditions without cracking.

Colored compounds are available for sale, but if necessary, the joints can be masked using finishing putty.

Glue with sawdust or paper

A cheap remedy for covering up cracks in a wooden floor is sawdust or pieces of paper combined with an adhesive base. The self-prepared damage-filling composition resembles putty in its properties and consistency.

If it is necessary to eliminate a small gap, the mass is prepared using small sawdust, and for more significant damage, choose those from which wood filler for cat litter boxes is pressed.

Cord

Repairing damage to a wooden floor using a cord is an old and proven method.

Operating procedure:

Tow

Inexpensive and quick way solving the problem. Flax tow, often used for plumbing work, is safe and environmentally friendly.

Work order:

Reiki

Sealing cracks in a wooden floor using slats is ideal for large, uneven damage - wood that has been seasoned adhesive composition, becomes flexible and easily fits into the gap.

Work order:

1. The crack between the boards is treated (cleaned, the surface is coated with an antiseptic).
2. Select or plan out slats that suit the size of the damage. It is best to use pine boards for this purpose.
3. The slats and cracks are treated with glue.
4. The slats are placed over the gap and driven into it using a hammer.
5. Parts of the slats protruding above the floor surface, if any, after completely dry Remove the glue with a plane.
6. The repaired floor is covered with paint or stain.

Oil paint and sawdust

The composition is prepared by combining one part of paint and varnish for wooden surfaces with 4 parts of fine shavings or sawdust. Mix the ingredients thoroughly until a homogeneous consistency is achieved.

Covering cracks with a similar mixture is carried out in 1 stage to eliminate minor damage; for large ones, several applications will be required.

Linseed oil and wax

The product can be used to eliminate minor defects on wooden floors. The components are heated, mixed, and the still hot composition is poured into the damaged areas.

Before starting work, you should thoroughly clean the floor surface so that no debris or dirt gets inside along with the mixture.

Epoxy glue with cement

Suitable for repairing small cracks and is reliable.

The ingredients are taken in equal proportions and mixed; immediately, before the mixture hardens, pour it into the cracks. It is necessary to fill the damaged areas so that a little product protrudes above the surface - after drying, the remains are cut off with a knife, the floor itself is sanded and painted.

Plywood

If the damage to the floor is significant, almost every floorboard is located at a distance from the other, use plywood, chipboard or OBS boards.
You can first hammer slats into especially large cracks and cover the entire surface with putty to improve the quality of the repair.

Work order:

1. In the most problem areas the boards are fixed to the joists using nails or self-tapping screws. The caps should be removed from them so that nothing rises above the surface.
2. Plywood is laid on the floor. Each sheet is fixed with self-tapping screws along the edges and in the center, the distance between fasteners is no more than 30 cm.
3. The flooring is sanded, and floor finishing material is laid on the surface.

For fixation plywood sheets It is recommended to use 36 mm long self-tapping screws with plastic dowels.

It’s quite easy to deal with cracks and crevices in a wooden floor yourself; the main thing is to follow the technology and procedure.

Wood, although warm, is capricious flooring material. None of the installation methods guarantees that there will be no gaps between the planks in the future. In this article we will tell you how to seal cracks in a wooden floor.

As you know, wood not only changes linear dimensions as a result of changes in temperature and humidity, but also dries out over time. In addition, rodents can contribute to the appearance of cracks and holes in the floor. In any case, repairs are required:

• Cosmetic - gaps are sealed various compositions or inserts.
• Partial – replacement of a damaged board or small area;
• Complete – refurbishment of the boardwalk or complete replacement of the covering.

How to seal cracks in a wooden floor? The most common method is to fill the seams using special ready-made compounds:

• Sealants;
• Wood putties;
• Construction foam, etc.

Mixing homemade putty composition.

Instead of construction chemicals You can prepare homemade mixtures to seal gaps in the floor. As a rule, the composition consists of two components - a binder (glue, paint) and a filler (sawdust, gypsum).

The next method is a little more labor-intensive - eliminating wide gaps between the boards, as well as between the covering and the wall using compaction. In this case, strips of wood, foam plastic, special caulking cords, etc. are used. Effective and practical, but in some cases requires additional adjustment and subsequent varnishing or painting.

The last method, the most expensive and costly, is to replace the floorboard with cracks and other damage with a new one that is suitable in size and tone.

The exact method for eliminating defects is selected based on the width of the seams, the nature of the damage, etc. Let's take a closer look.

Semi-liquid filling compounds for sealing cracks

In any series of construction chemicals from Russian or foreign manufacturer Tools for woodworking are available. They are great for eliminating minor defects. Including:

Pigmented silicone sealants

Used for gaps up to 1 cm wide, they have good adhesion to wood. After application, the composition must be leveled with a plastic or rubber spatula. As a result of polymerization, an elastic, non-shrinking seam is formed, resistant to water and household chemicals. A particular advantage is the durability of the plastic composition, which does not crumble or fall out due to seasonal expansion and drying of the floorboards.

The color indicated on the label may not match the real one, so ask the store for a display stand of colors. These are samples of finished products made by the manufacturer.

Acrylic sealants, paintable

A good analogue of the previous product, but with a slight difference. After application, the white paste polymerizes for 1 hour, then it can be painted. A very convenient way to repair floors coated with alkyd or oil enamel.

Tinted gypsum putties

Water- or oil-based compositions familiar to customers for gaps up to 1-2 cm wide. Apply with a spatula and compact thoroughly. The material shrinks, so re-application and subsequent leveling may be required. The putty dry surface must be sanded with sandpaper.

After drying, the finished putty becomes lighter by 1-2 tones, so when purchasing you need to choose a darker composition.

The downside of this product is its fragility. After a year, maximum two, the seam begins to crack, crumble, and absorb dirt. The material is in steady demand mainly due to price. The cost of a small package from VGT or Novbytkhim is only 50-60 rubles.

Epoxy putties

Semi-liquid, quick-hardening compositions based on polymer resin. As a rule, these are two-component compounds that, after drying, form a very strong (non-elastic) seam. The adhesion coefficient of this material to wood is unusually high, and, unlike conventional putties, the hardened mass does not crumble. Accordingly, already at next year You won’t have to look for something to cover up the floor defect again.

Epoxy grouts are used for narrow gaps no more than 3-7 mm wide, applied with a spatula. The shrinkage rate is low, so there is no need for re-processing.

Polyester pastes, colorless or white

Quick-hardening polymer grouts, one- or two-component, for filling gaps between boards no more than 5 mm wide. The mixture is suitable for old floor coverings, as it forms a strong, rigid seam. After application, the surface is leveled with a flexible spatula; painting in the same color as the main floor is allowed.

We have listed ready-made compositions. In search of how to fill cracks in a wooden floor, craftsmen often use such means as;

• polyurethane foam (pieces of polystyrene foam, fiberboard scraps, etc. are inserted into the gap as a frame);
• mixture of small sawdust and PVA or oil enamel;
• composition of cement and epoxy glue, etc.

Options homemade putties There are many options for filling gaps; they are formed according to the “what’s at hand” principle. The most reliable and proven, according to experienced craftsmen, is a mixture of wood flour and PVA. A thick paste is prepared from these components, which is applied with a spatula and carefully leveled. After drying and sanding, the surface can be coated with a protective varnish.

Sealing cracks using compaction method

If the boards “play” and the width of the gaps exceeds 1-2 cm, it is recommended to use inserts. They will help firmly fix the floorboards and remove squeaks. The first and long-proven remedy in this case is thin wedge slats.

How the compaction is carried out:

1. The gap must be cleared of debris and slightly expanded. Remove skirting boards and others decorative moldings no need.
2. Measure the width and make a wedge of appropriate dimensions from the slats.
3. Apply PVA or wood glue to the floorboards and insert.
4. Drive the lath tightly into the seam with a mallet or a regular hammer using a tamping block.
5. Remove the protruding surface with sandpaper or a plane.
6. Sand the sealed floor with a fine-grained sanding belt and cover it with varnish or paint.

As a temporary remedy before major repairs You can use a sealing cord on the floor. It is designed to seal cracks in log houses up to 3-5 cm wide. It is a kind of rope made of foamed polyethylene, rubber or tow. Working with this type of material is not difficult: the product must be carefully compacted into the gap using a chisel and hammer. And so that the seam does not stand out too much from the rest of the floor, a thin layer of tinted sealant, putty or a mixture of sawdust and PVA is applied to the surface.

Local replacement of the damaged area

What to do if mice have gnawed through the floor, and the gap in the wall-floor area exceeds 5-10 cm in width. Neither putties, nor sealants, nor even sealing ropes will help in this case. You can cover the top with a piece of plywood or chipboard, but such a blotch will simply get in the way and stand out too much. The best option– replacement of a board or a small section of the floor.

To prevent the repaired floor from becoming a victim of rodents again, some craftsmen recommend starting with creating a “barrier” for mice. In particular, under the coating in the area of ​​the mouse passage, you can pour cement mortar, mixed with broken glass or iron filings.

The next step is to remove all the baseboards and cut out the damaged area or strip using an appropriate power tool. New parts are glued or nailed to the base with hardware.

The last stage is sanding, or better yet, complete sanding of the floor, followed by varnishing or painting. If the shades of the floorboards differ by more than 2 tones, you can try to tint the planks with stain or protective and decorative glazes.

In case of severe damage to the entire floor area, some experts suggest sewing sheet materials over the wood - plywood, chipboard, OSB and others. This is a good option, but only if you intend to lay a new topcoat on top that is resistant to abrasion, dirt, and shock.

Eco-friendly, beautiful and durable wood floors have one drawback. Between wooden planks Due to changes in temperature and humidity in the house or for some other reason, cracks appear over time. They can be repaired even by someone who does not have special skills. There are several ways to extend the life of wooden floors, which you can learn about in our article.

Reasons for the formation of cracks in the floor

Gaps between boards bother homeowners for many reasons. If there is a ventilated foundation under the floor, then cold penetrates into the room through the cracks.

Due to the fact that various debris gets clogged into the gaps, the floors take on an unaesthetic appearance. In addition, the boards themselves may begin to rot.

The cause of cracks can be:

1. Drying of wood. This is the most common reason when using regular wooden boards. You don’t have to worry about drying out if the floor is made of factory boards treated with the “vacuum drying” method.
2. Installation error. Gaps may form immediately after construction is completed if the floor installation was performed incorrectly. In this case, the gaps arise due to the fact that the boards are “walking”.
3. Dry air. If the air in the room is dry, then there is no need to remove cracks on the wooden floor. After some time, boards pulled together tightly will go in “waves.” You can check air humidity using a hygrometer.
4. Small rodents. The cracks made by mice are not easy to repair. You must first get rid of the rodents themselves.

With timely care and careful operation of a wooden floor, you can only get by cosmetic repairs. The choice of method and means will depend on the size, location of the defects and the reasons for their appearance.

Traditional methods of sealing cracks

There are many “old-fashioned” methods of solving this issue that have been proven over the years. In some cases, they are more effective than the use of modern means.

Using the cord. Using a cord selected according to the width of the hole, you can seal cracks not only in the floor, but also on the walls. The cord will close the gap and eliminate the unpleasant creaking of the boards.

To carry out repairs, you will need to prepare a cord, rope or twine, putty, wood glue or PVA, and sawdust from any material. Work process:

• Cover the cord completely with glue.
• Make a mixture from sawdust, putty and glue.
• Deepen the cord into the gap so that there is from two to four millimeters from the floor surface to it.
• Fill the distance from the rope to the surface with the prepared mixture. The putty composition shrinks when it dries, so the gap is filled with the mixture with a small margin on top.

Frozen mixture coated with varnish or paint to match the wooden boards.

Glue with sawdust

Gaps and cracks can only be sealed with glue with sawdust, or mortar with the addition of cement. You should use fine sawdust and PVA glue:

If cement is added to sawdust and glue, then the following proportions must be observed to mix the mixture:

• glue – 2 parts;
• sawdust – 5 parts;
• cement - 5 parts;
• hot water– 15 parts.

First glue with water mixed until smooth, to which sawdust and cement are added. The resulting mixture should sit for about ten minutes. It can be given color wooden covering by adding pigment or thick oil paint.

The mass should be heated before use. This solution dries within two weeks. Only after this the surface leveled with abrasive materials.

Using slats

The slats coated with glue become very flexible and can be easily driven into the gap. Therefore, this method is considered very effective and is one of the most common. To perform the work you must:

Small defects can be eliminated a mixture of PVA and sawdust.

Chipboards and plywood

If between the floorboards there is a large number of various sizes cracks, it will take a very long time to seal them. It would be easier to use plywood or chipboards, on which the finishing coating is then laid.

Plywood can be fasten with dowels and self-tapping screws or with “liquid nails”, fixing them with ordinary nails. In places where screws are attached, the plywood may become deformed. To avoid this, holes should first be made in the sheets.

Paste, paper and copper sulfate

This is the most cheap way, with which you can get rid of cracks in a wooden floor. To complete it you will need:

It will be possible to paint the floor only after the composition has dried thoroughly.

Broken glass and cement

Glass and cement filled gaps putty on top. In stores you can buy a higher quality mixture, which consists of concrete mortar and aluminum chips.

Modern means

Today construction stores offer a huge selection of different products for sealing cracks in wooden floors.

Foam gun. By using polyurethane foam, you can seal the gaps and at the same time create additional thermal insulation. Work with the gun must be carried out quickly, since the foam freezes literally before your eyes. The gun is pre-adjusted for low feed.

A cocktail tube is placed on the spout of the tool for dispensing foam and flattened, which should be inserted between the boards. During operation, the foam should be pressed with a wet, soapy bar. If the tube does not fit into the slot, then you can simply lean it against the hole.

Excess foam can be cut with a knife only after it has completely dried. Otherwise, it will smear everything around, and the foam is very difficult to wash off. Polyurethane foam is destroyed by direct sunlight, so it must be painted over in several layers.

Silicone and acrylic sealant

Elastic material is suitable for floors that “play”. If it is not possible to fix them firmly, it is recommended to use silicone sealant.

It is very simple to use: the surface is cleaned and dried; the composition is drawn into a mounting syringe, the tip of which is lowered into the slot; The sealant is carefully squeezed out and spread with a spatula.

Silicone will remain elastic even after drying, so will last a long time. Available for sale silicone sealants different color.

Resistant to high humidity and temperature fluctuations acrylic sealants. They are easy to sand and can be coated with varnish and paint. Acrylic-based sealants are clear and do not have the vinegar smell that comes from silicone compounds. Created on water based acrylic sealant is easily washed off your hands.

In addition to the fact that they spoil the appearance of the apartment, dampness and drafts penetrate into the house through the cracks. The presence of voids can contribute to the appearance of cockroaches. They penetrate through all sorts of cracks. How and with what can you eliminate the gap in the space between the wall and the floor? More on this later.

Stages of work

Sealing cracks will not require much time and effort from residents. There are several stages of work:

1. The size of the space, its depth and length are determined.
2. The material for work is selected. It all depends on the size of the gap.

What materials can be used?

To seal a small gap, the size of which is no more than one centimeter, it is permissible to use such Construction Materials, like putty and cement. Mounting plaster is also suitable for use.

If the gap is from two to five centimeters, then it is better to seal it with polyurethane foam. If it is more than five centimeters, then the work will become more difficult. You'll have to buy other materials.

What needs to be done at the preparatory stage?

The filling of the resulting voids can be attributed to cosmetic repairs. How to seal the gaps between the floor and the wall depends on the type of damage, as well as interior decoration rooms. All preparation will depend on whether the walls and floors in the apartment are decorated. The plinth is removed, as well as the wallpaper. If the baseboard for the floor is high, it is worth attaching it back, then the seam will be completely invisible. When there is a layer of paint, it must be removed by stripping. Whitewash is washed away by water. Before starting work, the wall must be completely dry.

All accumulated dirt should be removed from around the work area. When a gap is sealed in an already renovated room, the wallpaper must be partially removed. If the coating allows, only the strip above the floor is removed. You need to buy a film and cover all places where dirt from work can get in. Protective coatings“save” floors from contact with polyurethane foam. The paint is difficult to wipe off the surface; precautions should be taken when painting. When planning work using water, it makes no sense to cover the area around with newspapers or papers.

What should I do to remove a large gap?

If it is necessary to seal the gaps between the floor and the wall and the voids are very large, then you can use foam or plastic. When you have unnecessary pieces of brick on hand, they are ideal for repair work. Large parts should be broken down into small components. The smaller the parts, the more evenly they will “settle” inside the gap. The entire cavity will be filled as a result. An important point there will be neat filling of voids. The task is to prevent further expansion of the resulting void.

Some people use alabaster in their work. This material is cheap and economical to use. Beginners in the repair business ask about how to dilute alabaster.

It is necessary to fill the void by one third, to a maximum of 50 percent. It is allowed to apply foam only in a thin layer; it is possible to apply several layers. It's worth waiting for the last one to dry before applying the next one. With this pouring method, there will be no excess foam and no flakes will fall out. Material consumption is significantly reduced.

How to fill a small or medium void between the floor and the wall?

The question often arises about how to seal the gaps between the floor and the wall if the space is small. To fill a small gap, you need to have precision movements and dexterity. Suitable for work soft materials. They must be plastic. It is important that the cavity filler has a high density. Such materials include construction felt. Tow is more often used. To prevent insects from settling in the cracks, they are treated with insect repellent sprays.

The material at hand should be rolled into rolls of small diameter, which is not very larger size cracks. The required filler is driven into the gap using a hammer. It is better to take a rubber construction hammer. It will help to smoothly fill the resulting void. It is necessary that the material is solid and there are no small parts. Usually cracks form in them.

If the cavity is very small and the tow will not fit into it, then a gypsum solution helps in this matter. It quickly fills all the cracks. The solution fills the space as much as possible. You can also treat the surface of walls with it.

2. We should not forget that foam tends to expand after filling the space. The moisturizing effect enhances expansion. It is necessary to carefully apply the foam in small portions.
3. Most favorable conditions for sealing cracks with foam - this is a temperature from plus five to plus twenty-five degrees Celsius. You must first warm up the balloon in water at the desired temperature.
4. Before starting work, the foam package must be shaken.
5. You can only work with specialized glasses and gloves. It is important to remember that the composition of the foam is quite caustic. It settles firmly on the surface and on clothes. If contact with open areas cannot be avoided, then you should wait until the material dries, after which it will be easier to remove.
