Slate is considered one of the most durable materials for roofing buildings. It is for this reason that it has not lost its popularity for several centuries. However, over the years, its appearance ceases to please, as the material loses its presentability. Don't be upset if your roof has become pale and unattractive. There is an exit. Enough to paint slate roof, and it will sparkle with colors again. There are some rules and guidelines regarding this process. In this article we will find out how to paint slate so that it is not inferior in beauty to modern roofing materials.

Before painting your slate roof, you need to prepare for the process. Firstly, we need to think about what tools and materials will be useful to us. So, to complete the task you should arm yourself with the following tools:

• Prepare a special brush for working with metal;
• Keep a drill and grinder handy;
• You will need glasses, respirators and paint brushes;
• High pressure jet washer;
• Antiseptic for construction purposes;
• Protective gloves;
• Paint (the best option is acrylic or enamel paint);
• Primer.

After necessary materials purchased, you can start next stage, namely to prepare the working surface.

Methods for cleaning a slate roof

Before painting flat slate, you should clean it of dirt and moss that appear during use. To accomplish this task, you can use several effective options:

• Cleaning with a wire brush. This method requires enormous physical effort and large quantity time, and the result of the work is not characterized by excellent quality indicators. If you choose this cleaning option, then make sure that the flat slate on the roof is dry, otherwise the paint will not adhere well;
• Using a drill or grinder. To carry out cleaning, a special nozzle is used, with which the old roof can get rid of moss and dirt. Thanks to electronic devices it is possible to achieve high quality and not lose speed of work;
• For the third option, high pressure water pressure will be useful. Perhaps this is the most effective method. To perform the work, it is not recommended to exceed the pressure value of 250 atmospheres. If you violate this rule, you can cause damage to the coating. This cleaning can be carried out in any weather conditions.

Attention! The third cleaning option demonstrates very high efficiency. So, working with an area of ​​100 square meters, you can spend a maximum of two working days.

Slate processing process

For your information! There is nothing better than a damp environment for fungal growth, so it is also necessary to apply a waterproofing coating to the work surface.

The slate surface becomes porous over time due to increased humidity, which leads to early damage and destruction. In order to improve the quality of the cover, hydrophobation should be carried out. These measures have a positive effect on the service life of the roof. Painting flat slate or any other type will help restore a neat appearance. It is best to carry out the procedure immediately after laying the material, but many developers do not think about this right away. They consider this option only in situations where the products have already lost their aesthetics. In the next section we will consider in detail this important and final stage of work.

Paint selection criteria

What is the best way to coat the surface of slate to restore both its quality and beautiful appearance? The modern range of paints forces developers to do Difficult choice. But how to figure out what exactly is suitable for a particular surface? We will answer this question in this section. Slate painting products are produced by both foreign and domestic manufacturers. Basically, they are made on the basis of acrylic or silicone. Let's take a look at the most popular types of paints:

• Acrylic or water-dispersed. This paint is applied to the slate surface after it has been treated with a primer. Thanks to this coating, protection against moisture and deformation is increased, the sliding characteristics of the products are improved, which promotes optimal drainage of precipitation from the roof. Painted slate will dry very quickly, thanks to the peculiarities of the composition. It should be noted that the product range is represented by a huge number various colors and shades.
• Enamel. The peculiarity of the coloring consistency lies in special binders and the possession good indicator moisture-proof properties and resistance to precipitation. After painting, the coating becomes stronger and better quality. Dyed material is less susceptible to fading, so it will retain the brightness of the color for many years.
• Paint in the form of liquid plastic. This synthetic material, which is based on bitumen, polystyrene or polyvinyl chloride. Despite the low cost, it should be noted that this paint is characterized by low moisture-proof properties and most of its types contain components that can cause negative impact on human body. Therefore, before you paint slate, think twice about the choice of paint material.
• Rubber. Today it is considered one of the most popular paints. Its composition is absolutely safe for humans and all living beings. With its help, you can improve resistance to wear, external corrosion and fungal infections, provide high protection against slipping of products, and the elasticity of the paint ensures stretching when small cracks form. The use of this particular paint increases the service life by several decades. But it is best to create two layers of coating, which will prevent deformation and destruction of roofing sheets.

Important! As you can see, each type of paint has special characteristics. Can they cover slate? The answer is simple: even necessary. However, not all of them are safe for health, so do not forget about it.

The most popular paint brands

The market for paints for construction purposes is replete with brand names from the most famous manufacturers. However, which one is best for staining slate? Today, the following manufacturers are in high demand:

• Dahbeshikhtund. Paint from a German campaign, characterized by excellent performance properties. Of course, its cost is much higher than its domestic counterparts, but its quality makes it a leader. It has high adhesive properties, good strength, and long-term operation. It is recommended to use it for tiles natural type and slate.
• Polyfarb. A Polish-made product made on a dispersion basis. One of the features is the ability to dry quickly, which significantly speeds up workflow. Also, thanks to coloring, resistance to moisture and ultraviolet radiation increases.
• Aqua. The creators of the paint are joint work Finland and Sweden. It dissolves easily in water. A distinctive feature is its resistance to alkaline environment. In practice, Aqua is used not only for painting slate surface, but also for concrete foundations.

Attention! These are not all paint manufacturers that offer a quality product. We have presented you with three of the most famous brands for working with slate. The choice is always yours!

Not so long ago, painting slate on a roof was an extremely rare occurrence, and it was done oil paint, which was associated with the fragility of the coating. Nowadays, painting this roofing material is commonplace, since the durability of modern painting compositions is disproportionately higher.

Of course, in order for the painting to turn out to be of really high quality, it is necessary to follow a certain technology and choose the right paint coating. Next we will look at all these nuances.

How to paint slate

First of all, let’s figure out how to paint the slate on the roof. You can often hear that painting slate and other asbestos-cement materials is extremely short-lived. Skeptics argue that the paint layer begins to crumble after the first winter, so it is better not to mess with this procedure at all.

In fact, everything depends on the choice of paintwork and compliance with technological requirements. Even in a year it will lose its attractiveness.

Today, deciding what to paint a slate roof with is not difficult. Special coloring compositions for coating asbestos-cement materials are produced both foreign and domestic producers. They are made on silicone or acrylic base, which ensures high reliability of the coating.

Among the most common paint coatings on the market for these purposes, the following brands can be distinguished:

• Triora- this is domestic slate paint made on acrylic base. This composition has excellent performance properties, including moisture resistance and light fastness. The paint is applied to the primed surface in two layers.

Initially, the composition is white, however, with the help of tints, you can give the coating almost any color and shade. Another advantage of this paint is its low price.

• KO-slate– this composition includes a mixture of silicone-based dyes and fillers. Has good adhesion, excellent decorative properties and resistance to mechanical stress.
• Kilpi from Tikkurila– paint for slate roofs, made with a modified acrylate dispersion. This is quite an expensive coating, but the high cost is justified high quality. The coating does not lose its elasticity even at very low temperatures environment.

When choosing paint, keep in mind that they differ not only in properties and composition, but also in consumption. Therefore, low cost does not mean savings.

It must be said that all these types of paints are intended for application exclusively to asbestos-cement surfaces.

However, on the roof there are often all kinds of metal constructions, This:

• Roof ridges;
• Visors;
• Chimneys;
• Fencing, etc.

Therefore, in addition to paint for slate, you should prepare compositions for metal surfaces in advance. For example, fire-retardant metal paints Polistil are suitable for chimneys.

Paint for metal surfaces – Zinga

Zinga electrically conductive paint can protect skates and other metal elements from corrosion. Moreover, it provides not only passive (barrier) protection, like ordinary paint, but also active (cathodic).

Painting a slate roof

Of course, you can involve specialists in performing this operation. However, before you make a decision, you should ask how much does it cost to paint a slate roof? It is quite possible that after receiving the answer, you will decide to do it yourself, besides, this process is not particularly labor-intensive and does not require experience.

Preparation

Like any other surface, before painting a slate roof, it must be carefully prepared for this. If the slate has been in use for several years, then work should begin by cleaning the surface from dirt. To do this, you can use ordinary metal brushes or a grinder with an appropriate attachment.

Advice! Special attention Pay attention to the northern slopes, where moss may form. All this vegetation also needs to be removed.

In the photo - preparing slate for painting

After cleaning, the roof should be checked for integrity.

If small cracks or breaks are found, they must be sealed with a special mixture, which you can prepare yourself from the following components:

• PVA glue;
• Fluffed asbestos;
• Cement.

The next step before painting the slate roof is to remove dust and debris that may have formed during previous manipulations. To do this, you can use water, the only thing is that the roof must dry thoroughly afterwards.

Advice! Before painting, it is advisable to treat the slate with antifungal agents, which will extend the life of the paint and the slate itself.

Primer

An important stage of work is the application of a primer recommended by the manufacturer of the coloring agent. It is this that ensures good adhesion of paint and slate, which means the durability of the coating. In addition, priming will reduce the consumption of the coloring composition.

You can coat the roof with primer using a roller or a brush. During this procedure, it is extremely important to ensure that there are no untreated areas left.

Painting

The final stage of work is the painting itself. For these purposes, you can use a roller and a brush, however, it is much easier and faster to apply the composition using a sprayer.

Advice! It is advisable to start painting the slate after they are finished. Otherwise, you risk staining the painted surface with paint.

The service life of asbestos-cement slate reaches 50 years. However, with proper care, the service life of roofing material can be significantly increased. One of mandatory conditions The durability of slate is its painting. As a result of painting, a protective layer is formed on the surface, and the roof itself acquires an attractive appearance.

Do I need to paint slate?

Asbestos-cement slate has long been considered the most popular roofing option due to its good performance characteristics and affordability. And today many people prefer this material when constructing buildings for various purposes.

Easy to install and inexpensive slate has some disadvantages:

• not attractive appearance;
• tendency to become overgrown with lichen and moss;
• gradual decrease in strength characteristics under the influence of weather conditions and external factors.

Slate is a porous material prone to microcracks. The moisture accumulated in the pores turns into ice during the first frosts and gradually “tears” the material from the inside. The same deformations are inevitable when lichens and mosses grow on the surface.

Painting asbestos slate will help solve these problems. After painting, a durable film is formed on the roof surface, covering access to water and microorganisms. As a result, the destruction processes are suspended, and the service life of the slate is extended by several years.

Thanks to the protective layer, the slate becomes smooth, atmospheric moisture is not retained on it, and snow and fallen leaves quickly disappear. Accumulated dirt can easily be washed off with a mini car wash or with water under pressure from a country hose.

In addition, painting solves another issue - the theoretical harmfulness of slate. This version is mainly distributed by manufacturers of advanced and expensive roofing materials. The essence of the problem is that the slate covering emits asbestos dust, which has a negative impact on the environment and human health. There are numerous refutations of this version. However, for those who doubt it there is optimal solution- painting the slate, which will completely prevent the release of asbestos dust.

So, painting a slate roof allows you to:

• improve the appearance of the roof and give it the desired color;
• smooth out the roughness of slate;
• prevent the formation of cracks;
• protect the material from the growth of vegetation on it;
• prevent dusting;
• increase the service life of roofing material by 1.5 times.

Slate paint must meet many requirements. Main selection criteria: resistance to temperature fluctuations, burnout and precipitation. An important indicator is the level of adhesion with asbestos cement.

The following groups of paints and varnishes are used for painting slate:

• acrylic enamels;
• alkyd;
• organosilicon;
• "liquid plastic"

Most popular acrylic compositions. They have rich tones various levels dullness. Types of acrylic enamels: water-soluble or organic solvent-based.

Water-dispersed acrylic paint for slate has a number of advantages:

• no pungent odor;
• fire and explosion proof thanks to water based;
• does not emit toxic substances;
• does not require a special solvent during the application process;
• drying speed - about 2 hours;
• formation of a waterproof film;
• The service life of the coating is 5 years.

• Alpina Dachfarbe (Caparol) - green, brown or red enamel, resistant to frost and weather conditions.
• “Roofing paint on slate” (Novbytkhim) - forms a matte coating that is resistant to the development of microorganisms. Produced in five colors.
• “Aquagel AK-1Sh” (Styrene) - paintwork material creates a smooth film on slate, from which water quickly drains. Distinctive feature- ease of roof maintenance.

Latex paint- a type of acrylic paint and varnish materials water based. It looks like thick mastic, and after drying it turns into a flexible, elastic film. This “rubber” coating does not crack, does not allow water to pass through and has excellent adhesion to slate. Among the colors, the most popular acrylic slate paints are 6005 (matte green), 5005 (matte blue) and 3009 (red-brown matte). Color range according to RAL.

Acrylic enamels based on organic solvents differ:

• higher durability than water-soluble paints;
• elasticity;
• high water-repellent characteristics;
• light fastness;
• longer drying time - about ten hours;
• acrid odor;
• moderate toxicity and fire hazard.

Important! If solvent-soluble acrylic paint is too thick, then it must be diluted with the solvent included in the enamel. Painting work should be carried out away from open sources of flame, using personal protection.

Alkyd slate paints dry quickly and form an elastic film on the roofing material that is not prone to cracking. Among the additional advantages alkyd enamel can be attributed:

• high coupling with slate;
• good moisture resistance;
• resistance to natural phenomena;
• It is not necessary to prime the surface before painting;
• service life - at least 5 years.

Examples of high quality alkyd paint:

• “Quick-drying enamel” (Impulse) - quick drying (within 1 hour at an ambient temperature of 20°C), no pungent odor.
• “Roof enamel” (Empils) - the strength of the protective layer, 10 colors.

Silicone paints- the most durable and reliable option for painting the roof. Silicone makes enamel elastic. Some types of silicone paints can fill microcracks up to 2 mm thick.

Important! Silicone enamels - best option for processing old roofing.

Qualitative characteristics of silicone paints:

• high elasticity;
• the ability to perform roof restoration and repair of cracks;
• fungicidal properties block the proliferation of microorganisms;
• excellent dirt- and water-repellent characteristics;
• silicones are fireproof and non-toxic;
• durability - service life up to 15 years.

Examples of high-quality silicone enamels:

• “KO-slate” (Silicon polymer) - forms a deep color and durable coating, produced in two primary colors with the possibility of tinting;
• "OS-5103K" (Silicon polymer) - used for decorative and protective painting of various building materials. It is characterized by increased resistance to chemical gases, alkaline and acidic environment. Thanks to these characteristics, the paint can be used in industrial enterprises.

Polymer paints a plastic film of matte or glossy texture is formed on the surface of the material.

Qualitative indicators of “liquid plastic”:

• 100% moisture resistance - the polymer film does not allow moisture to seep into the slate;
• quick drying;
• environmentally friendly and no fire hazard;
• resistance to UV rays;
• possibility of applying silicone enamel without using a deep penetration primer;
• it is permissible to apply enamel in frosty weather (down to -10°C);
• durability - service life is about 15 years.

Options for good polymer paint:

• Liquid Plastic (Denalt) is produced on a polyurethane-alkyd base, which gives the coating sufficient strength;
• PPG-1 (Comoil) contains polystyrene. During the drying process, a durable moisture-protecting layer is formed.

Important! Polymer paints dry very quickly. Therefore, it is advisable to paint with a spray gun.

Step-by-step painting of slate with your own hands

Most often, slate is painted with acrylic paints. Therefore, we will analyze the procedure for using this type of enamel.

Calculation of paint volume

The consumption of paints and varnishes depends on the area covered and the absorbency of the material. As a rule, for painting 1 sq.m. About 300 grams of slate will be used. paints. To determine the total volume of enamel, it is necessary to calculate the area of ​​the roof.

The procedure for calculating the area of ​​a gable roof:

1. Measure the length and width of the building. The data is taken taking into account allowances for the cornices (about 50 cm).
2. Perform the calculation using the formula: S=2*(a*b), where S is the required roof area, a is the length of the roof slope, b is the length of the roof.

The resulting value should be multiplied by the average enamel consumption. When determining the total volume of paint, it is necessary to take into account that for high-quality painting you will have to apply two layers.

Surface preparation

The longest and most labor-intensive stage is preparing the surface for painting works. The set of activities includes:

Important! You should start applying paint to the slate only after the primer layer has dried - no less than 12 hours later.

Slate painting technology

It is advisable to prepare the brushes in advance different sizes, in order to efficiently process the ends, corners and hard to reach places roofs. The paint is applied in two layers - main and finishing.

Important! It is permissible to paint flat slate using a sprayer. When processing wavy material, it is better to avoid it - there is a risk of uneven coloring.

The base layer is applied with special care, covering all areas from top to bottom. After this, the base coat must be left to dry completely and the paint must be reapplied.

The finishing layer “evens out” sharp paint transitions and creates a uniform, rich color of the roof.

Features of painting new and old slate

It is better to paint the new slate “down below” - before laying the roof. There is an opinion that the base layer should be applied on the ground, and the finishing layer should be applied after installing the slate. Proponents of this method argue their opinion possible damage enamel when installing sheets. However, many experts believe that the risk of peeling off the paint layer is associated primarily with the unprofessionalism of workers and the complexity of the design of the roof itself. Painting over local scratches at the top is much easier than applying a full coat of paint.

Old slate is more difficult to process due to a number of factors:

1. Wear of the structure. The sheathing elements weaken and sag over time. Walking on the roof can cause cracks in the slate.
2. Partial destruction of roofing material. Before painting old slate, you need to check it for defects. Replace unusable sheets and repair minor breaks.
3. Changing the structure of slate coating. Under the influence of precipitation and temperature changes, the material becomes friable - this creates a danger for workers painting slate.
4. The need to clean the surface from accumulated dirt and various growths.

Thanks to modern painting materials, it will be possible to avoid the dullness and grayness of slate. The main thing is to choose the right paint and stick to it technological process, then the result will please you for many years.

DIY slate painting: video

As the years go by, the appearance of the roofs of Russian houses is gradually changing; among them, it is increasingly rare to find options covered with inexpressive gray slate. But one should not discount this durable and inexpensive material. So that it looks no worse than newfangled roofing coverings with spectacular appearance, his “appearance” can be made more presentable.

Is it possible and why to paint?

Our country has been accustomed to seeing slate in a boring gray color for a long time. Today, this color discourages people from purchasing such roofing, especially given the numerous alternatives available on the building materials market. But this does not mean that slate cannot be painted, giving it the missing shine. There are varieties of paints that can be used on flat or wavy slate. The flat painted version will look beautiful and expensive on the facade of the house, and the wavy version will look great on the roof.

The use of paint is justified from the point of view of not only aesthetics, but also banal savings. This kind of roof improvement is possible, for example, if overhaul. If you approach the situation in this way, the cost of updating will be low. This approach can also be used as a temporary measure to postpone the issue of radical reconstruction of the roof for several years.

Coloring also solves many other problems.

• The paint binds asbestos dust, which is harmful to human health. Facades and roofs “dressed” in painted slate will be safe.
• Thanks to the applied paint, the waterproofing of the slate coating will improve, since the decorative layer fills microcracks and pores on the surface of the material.
• Moss will not grow on a painted roof, which is a common problem with slate. Fungus and various pests that find refuge on porous slate will also not be able to settle on a painted roof. As a result, the service life of the roof will increase.

• You can paint slate to any shade and achieve harmonious combination with the color of the walls of the house.
• A coat of paint on the slate makes it look smooth. Water drains more easily from such a roof. There is no snow on it. Such a roof is easy to clean by spraying it thoroughly with a hose.

The only problem you may encounter is that the staining will have to be repeated periodically. And this is not a matter of minutes. Although, on the other hand, without re-laying the entire roof, you can “rejuvenate” it from time to time.

LMB selection

To finish slate, the appropriate paint and varnish product must be selected very carefully. It must be resistant to strong temperature changes, precipitation, not fade for a long time, and have good adhesion to the surface of asbestos cement.

The following types of paints exist:

• acrylic;
• silicone;
• alkyd;
• liquid plastic.

Let's look at the advantages and disadvantages of each type.

Acrylic paint

Available in water-based and organic solvents. Has good waterproofing properties. When painting, it penetrates into the smallest depressions and cracks, preventing moss and fungus from multiplying in them. Does not burn, adheres well to the surface.

Does not have an unpleasant odor. But it may have an excessively liquid structure and leave streaks on the surface during painting. On the market you can find high-quality water-based acrylic paints made in Russia, Germany, Finland, and Poland.

Water-based acrylic types include so-called rubber paint. Unlike the usual composition, it is a mastic with a thick consistency. Once dry, this paint turns into a film with properties resembling rubber. She clings tightly to roof surface without leaking water or cracking.

This paint does not burn and dries within a couple of hours. However, with all its advantages, it cannot be called harmless. It is toxic, so when dealing with it, you need to properly protect your skin and respiratory tract. On sale it is called “Rubber Paint”.

The second group of acrylic paints contains resin and a solvent, which is usually white spirit. Depending on the percentage of resin, the degree of dullness of the composition changes. The more of it, the better the gloss of the dried paint.

This type of acrylic, compared to the water-based version, differs in that it forms a more durable film, repels water better, is also more elastic and is able to retain color longer. At the same time, this paint has a very sharp bad smell which creates discomfort at work. There is a large selection of such paint and varnish products on the market. Among famous names Russian-made Shikril is often mentioned.

Silicone paint

This variety is considered to be the most durable and reliable for slate. Silicone makes the paint coating elastic. When painting, the composition penetrates into cracks to a depth of two millimeters.

During repairs, they are used to repair quite large damage to the roof. This paint does not allow various microorganisms to multiply on the roofing material and does not allow water and dirt to pass through. Non-toxic, fire safe. With it, the “lifetime” of slate increases by about five years.

It adheres perfectly to the surface of the roofing material, but after ten to fifteen years it fades greatly, losing its visual appeal. It should be borne in mind that the price of such roofing paint is quite high.

"Liquid plastic"

This polymer paint, which, after hardening on the surface, turns, according to its name, into a layer of plastic on slate. Externally, it may look matte or glossy. "Liquid plastic" completely insulates roofing material from water, dries quickly after application.

The paint is environmentally friendly, does not burn, does not lose color, is resistant to severe frosts. You can work with it at temperatures down to -10 degrees. Will last ten to fifteen years. Flaw " Liquid plastic"is that it is toxic. Requires skin and respiratory protection during application to the surface.

Alkyd paints

They are created on the basis of alkyd resins and organic solvents. They dry quickly, creating an elastic film on the surface that does not crack. They adhere well to slate and reliably protect the roof from water.

This paint also does not require preliminary priming. The service life is short - only five years. There are good alkyd paints of foreign and domestic production on the market.

Usually green, red and brown colors , they are the most common, but sometimes you want something special. In such cases, tinting comes to the rescue - a process when the necessary shades are obtained by mixing pigments or paints. Tinting services are offered by paint production companies. You can also achieve the desired color yourself. To do this, add tinting paste to the existing paint and stir using a mixer.

The success of painting a slate roof largely depends on preliminary preparation to this process.

• To ensure that any chosen paint remains durable for many years, the slate plates must be thoroughly cleaned. All dirt can be removed wire brush. You will have to make a lot of effort to remove all the dust, stubborn moss, old leaves and branches from the roof. You need to start this kind of work on a fine day. Wet slate is a rather fragile material, so it is better not to clean it after rain.
• If you have skillful use of the tool, you can use a grinder with a grinding attachment. In this case, it is important not to overdo it with pressure, otherwise the roof can be damaged. Working with such a tool will not speed up the process, but the quality of cleaning will be much higher.
• The easiest and fastest way to remove all dirt from the roof is with water. It must be supplied under pressure from 200 to 250 atmospheres. If the stream is weaker, not all the dirt will come off, but if it is stronger, the slate will break.

• Treatment can be carried out using a brush, roller or spray. It would be a good idea to apply antiseptic to the roof several times.
• After completing the procedure, the composition should be absorbed into the slate and dry.
• The next stage is surface treatment water-repellent composition, since water is precisely what primarily negatively affects the porous structure of the slate covering.

• At the next stage of processing, a primer is applied. It makes the surface smooth, removing microcracks and roughness. In addition, if priming is not carried out, the binder contained in the paint will be absorbed into the porous slate, and decorative coating will not be able to hold on firmly. In addition, thanks to the application of primer, it will be easier to cover the slate with paint, its consumption will be less and it will lie more evenly.

There are special primers, among which acrylic ones are considered the most effective. They penetrate into the deep layers of slate, strengthen the surface and fill the pores.

You can also use the paint itself, which you plan to cover the roof surface with, as a primer.. It is diluted with a solvent. When treating the surface, such soil penetrates into the upper layers of slate, filling microcracks and pores. Thanks to this, the layer of ordinary paint adheres tightly to the base.

Priming can be carried out at +5 and +30 degrees. The primer takes about twelve hours to dry, after which paint can be applied.

Coloring: features

You can do such work without the involvement of a specialist, as they say, with your own hands. It is best to apply paint in two layers, as both craftsmen and professional finishers advise. One will be basic, and the second will be finishing. Base layer must thoroughly cover the entire roof or flat slate surface on the façade, including ends, corners and other structural details. This takes two-thirds of the total volume of paint.

The second layer is applied after the first has dried. Thanks to it, the roof and walls receive a uniform color. To work, you can use a brush or spray. Experienced people do not recommend using a roller, as in this case it is inconvenient. It is best to paint with a spray gun, but in corners and joints you will not be able to do without a brush.

For such work, it is advisable to choose a warm and cloudy day with no signs of precipitation. It is important that the next one be the same. If it is humid or too hot outside, painting is impossible. On average, one hundred to two hundred grams of paint are consumed per square meter of area, provided that two layers of coating are applied. But you should purchase the material with a reserve in case of additional costs.

Now let’s look at the nuances associated with coloring different slates.

New

Obviously, when installing a new slate covering, it is better to carry out all the work associated with creating beauty on the ground. Experienced people advise dividing this process: finishing layer Apply paint already on the roof, because during installation of the roof, pre-painted sheets of material can be scratched.

Although, again, everything will depend on the specific situation. If the roof area is small, the slope is not strong and real professionals get down to business, the risk of damaging the surface of the painted slate sheet is significantly reduced. Sometimes it’s easier to do all the stages of paint processing on the ground, and then correct the damage in selected places on the roof surface.

Old

With old slate there will be much more hassle. Often, when it comes to painting a roof that has been in use for many years, the structure itself has already weakened. By stepping on it, you can break the slate or, at least, provoke the appearance of new cracks in it. Over the years, such roofing material becomes loose. So being on it can be dangerous.

Before work directly related to painting, you will have to carefully examine the roof surface. Longitudinal and transverse cracks and breaks appear on old slate. Sometimes damaged roofing sheets are easier to replace, although they can also be restored.

Many roofs of buildings and structures are covered with slate. Currently, this roofing material has many competitors, but slate has its niche in construction market. New materials intended for roofing look much more attractive, primarily due to their bright colors. However, this advantage can be easily offset by painting a slate roof. At the same time, it is possible to extend the life of the roofing material. But not every paint is suitable for this procedure. So what is the best way to paint slate? What paint and varnish products are intended for these purposes, and how to apply it correctly to the slate surface?

• profiled sheets;
• roofing panels;
• flat slabs.

Slate sheets with a wavy shape are painted with acrylic paints designed specifically for this roofing material. At the same time, the decorative qualities of the roof are increased, and its service life is significantly increased. Weather-resistant acrylic paint forms a durable protective layer that improves performance characteristics material, namely:

• protects sheets from destruction;
• increases their frost resistance;
• reduces the degree of water absorption;
• reduces the amount of asbestos released into the environment;
• increases the service life of slate sheets by 1.5-2 times;
• prevents the growth of mosses and lichens.

If for any reason the paint layer is damaged on a separate section of the roof, then restoration work is carried out immediately, without waiting for the next general repainting of the roof. After all, slate, being a porous material, quickly becomes dirty under the influence of precipitation and takes on a very unsightly appearance.

Paint and primer for slate: Shicryl

Among the special paints and varnishes produced to protect slate is Shicryl acrylic paint, which is based on organic solvents. This paint is used for finishing not only asbestos-cement slate, but also concrete plinths, cement-sand tiles and others. external surfaces, requiring alkali-resistant painting.

Using Shikril paint, they renew damaged areas of previously painted surfaces that require urgent repairs. The basic range of colors includes:

• white;
• gray RAL 7040;
• burgundy RAL 3011;
• brown RAL 3009;
• green RAL 6032.

It is possible to order a different shade of paint.

Shikril - paint for slate

Shicryl paint can be used to paint both old and new roofs. The paintwork has:

• water-repellent properties, otherwise called hydrophobic;
• high levels of coverage and light fastness;
• special elasticity when exposed to low temperatures.

Application of Shikril paint

1. The surface of the slate roof is cleaned of dirt, dust, and remnants of previously applied paint.

2. Apply the preparatory layer with the primer of the same name Shikril-Grunt, which is also intended for work on slate. For application use a brush, roller or spray gun. The roof is primed in one or two layers, with the next layer applied after completely dry previous one. Usually an hour and a half is enough for this. Work is carried out at positive temperatures of 15°C and above. The roof surface must be dry before starting treatment.

Important! Using a primer allows you to reduce the cost of painting slate by saving paint.

Paint the slate roof sequentially from top to bottom, thoroughly mixing the painting composition

4. Shikril paint is applied in two layers using the same tools used for priming the surface.
