Cold wall insulated the kitchen with penoplex*, and at the same time received beautiful decor in the form of red mountain sandstone.

Required: foam sheet (1x1.5 m, 2 cm thick), felt-tip pen (you can use a marker), knife, primer, finishing putty, acrylic paint, acrylic lacquer.

Sheet preparation

I measured the partition under the window and cut a blank from a sheet of foam insulation according to these measurements. I marked the outline of the stones on it with a felt-tip pen and numbered each element so that when gluing it to the wall I wouldn’t get confused in the order.

Carved texture

Holding the knife at a right angle, I cut the insulation sheet into pieces. In each resulting workpiece, I cut off the corners in the direction from the center to the edges, giving the details the texture of stone (photo 1). I laid them out on the table by number.

On a note
Penoplex cuts well with a regular knife, leaves virtually no debris and does not crumble. In places where the seams turned out to be narrow or the stones were longer and did not lay out evenly, I trimmed them with a knife directly on the wall.

Pasting the wall

I cleaned the wall of old wallpaper and primed it. I diluted the putty to the consistency of liquid sour cream. Starting with stone number 1 and further in order, I applied the resulting solution to the back side of the blanks and glued them to the wall. The seams were covered with the same putty.

Painting

After the putty had dried, I painted the stones with brown paint with the addition of white color. More light shade tinted the protruding texture and after about 5 minutes wiped it with a damp sponge to even out the color and give the stone a more natural look (photo 2). Dried it. I varnished it in two layers with intermediate drying.

I designed the corner under the ceiling in the same way. (photo3). After painting and varnishing this decorative rock has become very hard and is in no way inferior to gypsum analogues.

Final stage

Added given style rooms, decorating the opposite wall with a stone made from a mixture of tile adhesive and starting putty(1:1), diluted with water until smooth. Kneaded the mass well in small portions. The previously prepared area was covered with soil and dried. Wearing gloves, I applied a layer of mortar about 1 cm onto the wall with my hands.

I crumpled up a piece of paper and walked it over the area with the solution, imitating the texture of stone. After 20 minutes, I drew the outline of the stones with the handle of a teaspoon. Dried it. Primed. Painted by analogy with sandstone from penoplex (photo 4).

Preparing the base	In some cases it is not required , including for bases: wood, plasterboard, plywood, DSP, OSB, chipboard, MDF, polystyrene foam. Direct installation!			In most cases it is requiredpreliminary preparation of the base. The cost of preparation is 50 - 300 rubles/m2.
	Careful leveling of the surface is required.		For highly absorbent surfaces, preliminary priming is advisable.

FS- Glue . Highly elasticglue for flexible stone, after drying it becomes almost transparent. It has high adhesion, is resistant to deformation, water- and frost-resistant. Can be used on plasterboard, gypsum board, GSP, chipboard, OSB , DSP, FTP, polystyrene foam, metal, concrete, stone, wood. Suitable for indoor and outdoor use (at positive temperatures). Uneven surfaces If necessary, level with leveling mixture. The glue is applied with a brush or roller to the surface to be glued. Consumption 80 - 200 ml/m2 depending on the porosity of the surface to be glued. Ideal for creating a “glowing” stone, as well as for butt stickers. When gluing “with jointing”, moistened tinted sand is rubbed into the glue remaining on the surface between the tiles of flexible stone.

Universal facade adhesiveALLFIX http://www.allfix.ru/

Methanol-free, heavy-duty, all-weather, moisture-resistant. Used for both external and internal work. Operating temperature range from -10 to +30! If necessary, level uneven surfaces with a leveling mixture. The glue is applied to the surface to be glued with a roller or notched trowel in strips over the entire surface. After 1-2 minutes, a flexible stone is applied. Consumption: when applied with a roller 300 g/m2, when applied with a notched trowel 600 g/m2

Highly elastic cement adhesives are also used for gluing flexible stone, for exampleCeresit SM 17 http://www.ceresit.ru/products/glues_for_tiles/93/

Flexible stone sticker FS- Stoneat internal works simple and sufficient general recommendations. The surface must be durable, clean and dry. "Old plasters" check for peeling, if necessary, replace loose layers of plaster, the rest treat with primer. Uneven surfaces when using adhesives FS- GlueAnd ALLFIX If necessary, level with leveling mixture. When using glue Ceresit SM 17 perform preliminary leveling of the surface if unevenness exceeds 1-2 cm. When sticking to drywall, gypsum board, chipboard, OSB, the seams between the boards should be reinforced with sickle tape, and the corners should be reinforced with a painting profile. The tape and profile can be applied to the tile adhesive used. When gluing to unprepared walls, follow the recommendations for outdoor work given below.

Sticker on load-bearing bases (brick, concrete, cellular concrete)

Installation of flexible stone on brick and concrete.

This group of materials includes all other materials with similar characteristics (smooth, non-absorbent and non-deformable surface), except plastic. Plastic has significant thermal expansion, so for external work it is not advisable to use plastic as a base; in extreme cases, it is possible to use glue FS- Glue.

Insulation. If there is a need to insulate a wall made of such material, you can use EPS polystyrene foam or mineral wool. Optimal material for insulation systems with flexible stone on smooth, non-absorbent surfaces - EPS polystyrene foam. Before installing insulation, the wall should be prepared in the same way as for installing tiles. (See below for the sticker on the insulation).

Preparing the base . For non-adhering flexible stone using glue FS- GluePre-level the surface with Ceresit CT 29 putty. For glue ALLFIXSuch preparation is carried out when the surface is significantly uneven. For cement-based adhesives brick surface must be treated with Ceresit CT 16 adhesive primer, and concrete with Ceresit CT 17 penetrating primer.

Tiles can be glued directly to a primed surface using any quality tile adhesive for exterior use. To form seams gray use gray glue Ceresit CM 17. For white seams - white glue for outdoor use Ceresit CM 115.

Installation of flexible stone on cellular concrete, aerated concrete differs from that described above in that to prepare the surface for adhesives FS- GlueAnd ALLFIX Ceresit CT 24 putty is used. And for cement-based adhesives, it is double-treated with Ceresit CT 17 penetrating primer.

Sticker on frame walls (OSB, TsSP, FTP).

Installation of flexible stone on OSB, DSP.

OSB(oriented strand board) is a board made from several layers of pressed wood chips. Moreover, these layers are located at an angle of 90 0 to each other. The surface of the plate is treated with paraffin. OSB board is not the easiest base for “wet” work; this is due to significant deformation of the board when humidity increases. OSB boards There are different qualities, despite the same declared brand OSB-3. Plates that are supplied to Russian market USA and Canada (Arbec, Norboard, LP, etc.) are of lower quality than European ones. They have low density and are practically unprocessed. The densest board made in Germany (ie Glunz). For external walls frame house OSB board with a thickness of at least 12 mm should be used high density. A cheap Canadian stove is not suitable for this. The best option use of OSB boards with flexible stone cladding FS- StoneThese are SIP panels. They are quite rigidly connected to each other and provide acceptable geometry.

DSPthese are gray concrete slabs with a light filler of sawdust. Inexpensive and practical construction material. For the external walls of a frame house, a slab should be used DSP thickness not less than 12 mm. DSP plate-1 is superior to the TsSP-2 brand in terms of strength and geometry accuracy. The DSP board has two disadvantages: deformation due to fluctuations in humidity and high absorbency.

Surface preparation . The seams between the slabs should be reinforced with sickle tape, the corners and slopes of the windows should be reinforced with a painting profile. The tape and profile can be applied to the tile adhesive used. For adhesives FS- GlueAnd ALLFIX such preparation is sufficient. For cement-based adhesives, the surface must be treated with a penetrating primer. Ceresit CT 17. It will eliminate the absorption of moisture from the tile adhesive. And for the base from OSB additionally treat the surface with an adhesive primer Ceresit CT 16. It will provide a rough surface and protect against coloring pigments.

The tiles can be glued with any of the above-recommended adhesives or using any high-quality elastic tile adhesive for external use. Attention! OSB and DSP boards are subject to deformation, so elastic adhesive is required (elasticity index S1 or S2). To form gray seams, use elastic gray glue (Ceresit CM 17 or Lugato Flexibel). For white seams - elastic white glue for exterior use (Ardal Best S2, Ardex X77W, Mapei Granirapid). You can also use white Ceresit CM 115 glue with an elasticizer Ceresit CC 83.

Installation of flexible stone on fiber cement.

Flat slate is sheets of concrete reinforced with asbestos fiber (asbestos cement) or polyester fiber (fiber cement). As a variation there is the so-called aquapanel, this concrete sheet, reinforced with fiberglass mesh. Aquapanel is available for interior and exterior use. Fiber cement panels are quite dense, so they do not absorb moisture and practically do not deform due to humidity fluctuations. Similar materials - perfect solution For outer skin frame house facing with flexible stone FS- Stone.

Surface preparation Federal Targeted Program and gluing flexible stone are similar to working with DSP except that there are no increased requirements for the elasticity of cement-based adhesives, for example, Ceresit CM 115 can be used without an additional elasticizer.

Sticker for insulation (expanded polystyrene, mineral wool).

Installation of flexible stone on EPS foam polystyrene foam

The optimal brand of foamed polystyrene for use in the facade insulation system PSB-S 25 (density 15-25 kg/m3). It is permissible to use denser brands. To the base ( façade wall) polystyrene foam is attached with glue ALLFIX or with special adhesive for polystyrene foam (for example Ceresit Thermo Universal or Ceresit CT 83). Foam boards are installed closely, without gaps or cross-shaped seams, similar to brickwork. No earlier than 48 hours later, the polystyrene foam slabs are additionally fixed with disc-shaped dowels (so-called parachutes). The dowel caps must be recessed flush with the surface of the insulation. The length of the dowel is selected so that it enters the base at least to the depth recommended by the dowel manufacturer for the specific wall material (more for aerated concrete than for reinforced concrete). The consumption of dowels is 5-7 pcs per m2.

Tiles can be glued directly to the surface of polystyrene foam using adhesives FS- GlueAnd ALLFIX or high-quality cement-based tile adhesive for exterior use. To form gray seams, use gray glue (Ceresit CM 17 or Lugato Flexibel). For white seams - white glue for external use (Ceresit CM 115).

Installation of flexible stone on extruded polystyrene XPS (appearance: very dense plates of fine-porous insulation orange color, brands Styrofoam, Penoplex, etc.) is similar to working with foamed polystyrene, except that when working with it It is not advisable to use adhesives on cement based due to the difficulty of surface preparation.

Installation of flexible stone on mineral wool

Dense plates of pressed thin stone fibers of gray-green color, packed in thermo-shrink film. Common trade marks- Paroc, Rockwool. For facade systems with flexible stone FS- StoneIt is permissible to use mineral wool with a density of at least 130 kg/m3. This is, for example, Rockwool Fasad Butts or Paroc FAB 3.

Mineral wool slabs are installed on the pre-prepared façade wall as follows. Glue is applied to the plane of the insulation board using a large comb. ALLFIX or adhesive composition for mineral wool Ceresit Thermo Universal or Ceresit CT 190. Mineral wool slabs are installed closely, without gaps or cross-shaped seams, similar to brickwork. Not earlier than 48 hours (for ALLFIX glue after 24 hours), the slabs are additionally fixed with disc-shaped dowels (so-called parachutes). The dowel caps must be recessed flush with the surface of the insulation. The length of the dowel is selected so that it enters the base at least to the depth recommended by the dowel manufacturer for the specific wall material (more for aerated concrete than for reinforced concrete). The consumption of dowels is 5-7 pcs per m2.

Preparing the insulation surface . A base layer of plaster reinforced with Ceresit Thermo Universal or Ceresit CT 190 fiberglass mesh should be applied to the surface of the mini-slab. There is no need to prime the mini-slab. It is recommended to level and reinforce external corners and wall openings with a corner painting profile. The profile can be secured using a base layer of plaster.

The tiles can be glued to the surface of the base layer after 24 hours using adhesives FS- GlueAnd ALLFIX or high-quality cement-based tile adhesive for exterior use. To form gray seams, use gray glue Ceresit CM 17 or Lugato Flexibel. For white seams - white glue for exterior use Ceresit CM 115.

Sticker on permanent formwork (Durisol, Velox, IZODOM).

Installation of flexible stone on Durisol, Velox formwork similar to working with DSP except that above the surface permanent formwork VELOX are embedded parts made of thick steel wire. Over time, they will be able to stain the seams of flexible stone cladding with rust. Therefore, before installation, they need to be painted over with nitro enamel or other suitable paint and varnish composition. In addition, in order to hide the irregularities formed by the embedded parts, when working with cement-based glue, you should use a comb with a large tooth (6-8 mm). This will increase glue consumption. And when working with adhesives FS- GlueAnd ALLFIX During the construction stage, the embeds should be “buried” into the VELOX slab so that they do not protrude above the surface.

Installation of flexible stone on IZODOM formwork completely similar to working with expanded polystyrene EPS.

Insulation of premises is a very relevant topic nowadays, because energy resources are not getting cheaper. One of the most popular insulation materials is penoplex, and we want to talk about the scope of its application. Especially actual question– this is a penoplex finishing, and we will talk about this in detail.

Penoplex insulation and finishing

Interior work

Everyone knows that the insulation should be located with outside walls. However, such an arrangement is not always possible: the facade has architectural value, access to outer surface it is difficult or there is no way to pay for the work of high-altitude workers. Then they resort to indoor installation thermal insulation, and the most convenient material for this is penoplex ().

From a chemical point of view, penoplex is extruded polystyrene foam High Quality, the thermal conductivity of which is reduced by 30% as a result of special treatment compared to conventional foam, although the price is slightly higher.

Also worth noting:

• more durable and resistant material structure;
• improved sheet forming;
• increased surface adhesion to adhesives and finishing solutions.

Important! A significant advantage of expanded polystyrene is its absolute hydrophobicity; the material is not afraid of moisture, does not react with water and does not dissolve in it, practically does not absorb vapors and particles of water into its structure, and does not rot. All this allows us to recommend this type insulation for various types works on thermal insulation of building structures.

To install the material on the walls from the inside of the room, you can use two methods:

• dry,
• wet.

The dry method involves installing a heat-insulating layer under a hard covering - lining, gypsum-fiber sheets or panels.

In this case, the material is placed between the covering and the wall after the frame is built, which is then covered with sheets of drywall, boards, plywood or other finishing material. Obviously in this case, since it is covered with other material.

Another thing is the wet method:

• here the sheets are mounted on the wall;
• then they are puttied or plastered.

In this case, finishing is carried out directly on the surface of the insulation, and only then this layer is covered with paint or wallpaper.

The work is not particularly difficult; it can be done alone with your own hands; only minimal skills in using a spatula and a drill are required:

• The wall is cleared of old decoration up to brick or concrete base, then repair cracks and other defects, after which the surface is primed;

• Starting from the upper left (or right - whichever is more convenient) corner, they begin to mount the sheets on the wall. To do this, glue is applied to them, pressed and fixed with disc-shaped dowels. The seams between the sheets are shifted in each row by half a sheet like brickwork;

• After the wall is completely covered with penoplex, you should carefully apply glue or fill the seams with sealant. You can also use polyurethane foam. In addition to the seams, the entry points of the dowels are filled with glue;

• Before finishing the penoplex, it is covered with a fiberglass reinforcing mesh. It serves for better adhesion of putty or plaster to the surface. vertical wall. The mesh is stretched and applied to the insulation layer with glue; for convenience, you can pre-fix it with a construction stapler;

• When the mesh and glue have dried, the entire wall is primed with a deep penetration compound;
• When the primer has dried, you can begin applying the putty. To do this, pour the dry gypsum mixture into a bucket of water (about half) and mix the solution with a drill with a mixer attachment. The material is brought to the consistency of thick, fatty sour cream;

• Using a wide metal spatula, apply the putty evenly thin layer over the entire surface of the wall. After the layer has dried, it is rubbed with a polyurethane or emery grater to a smooth, uniform surface;

• Before painting, a leveling agent is applied to the first layer of putty. finishing layer, which is then also polished with a grater. It is convenient to use an electric grater with replaceable abrasive inserts;

• The sanded putty is painted or wallpapered.

Important! During the installation process, do not forget to cut holes in the polystyrene foam for sockets and switches.

Exterior works

For exterior work, polystyrene foam is also used, which is mounted:

• or wet method followed by plastering or other cladding;
• or placed under a ventilated façade.

When laying wet, the work procedure does not differ from a similar coating interior walls. The only difference is the use facade plasters and putties at the finishing stage.

In addition, after gluing the reinforcing mesh, installation is possible façade views cladding:

• stone,
• tiles,
• porcelain tiles and others.

At frame structure façade insulation is laid between the frame slats, fixed with glue and dowels (sometimes a gap is left between the wall and the foam plate, fixing the sheets between the slats polyurethane foam) and fill all cracks and joints with sealant or foam.

• block house,
• linings,
• panels made of metal or plastic,
• porcelain tiles, etc.

Important! When using expanded polystyrene as external insulation, it is important to choose a non-flammable material, since otherwise the facade may catch fire and release toxic smoke.

Conclusion

Penoplex can be used for internal and exterior finishing walls for the purpose of their insulation. Working with this material is easy; our instructions are suitable even for a novice builder ().

The unclear points are clarified by the video in this article.

The question of how to decorate a wall with a foam stone look with your own hands is quite relevant today. Such decorative panels they finish all kinds of surfaces, from edging on mirrors or windows to the entire wall area.

The popularity of the material is explained by the light weight of the structure and ease of installation, which is especially important in apartments located in multi-story buildings where the use of heavy bricks is impossible.

Making your own decor

To make imitation brickwork from foam plastic with your own hands, it is recommended to use fine-grained polyurethane panels, which have good heat resistance and do not crumble.

If it is not possible to purchase such material, you can replace it with ordinary ceiling tiles.

In addition, you need to prepare in advance following materials and tools:

• stationery knife;
• electric soldering iron;
• glue, putty;
• primer, varnish.

In addition, you can use sheets of construction extruded polystyrene foam, since it has characteristics that are ideal for this purpose.

View comparisons physical properties materials can be found in the table below.

Work order

Finishing a wall or a separate element of a room under brick or a natural stone beneficially transforms the surface, making it more aesthetically pleasing and attractive. In addition, the material is a good heat insulator, so it will act as insulation.

Photo instructions for making foam decor

Procedure self-made tiles looks like this:

In addition to the described method, there is another option for making imitation brickwork from foam plastic. It differs from the first in that it uses not only a lightweight heat insulator, but also cement with quartz sand. Detailed instructions for imitation brick, watch this video:

Based on the fact that other components are used, the order of work for their manufacture will also differ. However, it should be noted that there is nothing complicated in it, and even a person who has never been involved in similar work can cope with it:

The procedure for both manufacturing methods is not complicated. The result will not keep you waiting, but will delight you with the transformed appearance of the room immediately after application.

To emphasize the effect of a natural equivalent, and to make the surface imitating stone more like the real thing, it is recommended to use paint of several shades. In this case, the main color is pre-coated, and the secondary shades are painted with a dry brush.
