1. How to glue the stone on the concrete walls

Stone - hard type of cladding. Weight 1m² large format artificial stone may exceed 50 kg. Therefore, on the walls, foundation and subgrade house will fall an additional burden.

Conclusion: The reload option stone cladding in the construction home on the stage of its design, the choice of the type of foundation and walls.

The most rational approach - Lift a stone facing "box" of solid brick or concrete. This will provide a margin of safety. That's what the user entered the portal with the nickname swin1983.

I have built a modern house with a flat roof on monolithic technology. Fundam - FBS blocks stacked below the freezing depth. Wall thickness - 140 mm. "Box" is insulated with extruded polystyrene foam and 100 mm thick. Facade artificial stone. Some of the stones weigh 25 kg. Long thought how to stick a stone, so it does not fall off.

House area 315 m².

The main stages of construction:

• Construction of the foundation.

• Construction of walls and ceilings.

• Installation of insulation.

• Sticker stone.

And as you stuck to the stone facade?

My technique of attaching a stone step by step:

• If the foam has turned yellow from the sun, clean it with a brush.
• Mechanically attach the foam reinforced with glass cloth mesh.
• Using a spatula prime the surface of the same glue, how kleite stone. The layer thickness of 5-6 mm.
• Moisten the surface.
• Glue the stone simulating random masonry. The gap between the stones in thick finger. Lower stone should be supported.
• Powertrowel seams.

The user advises stick stone at the outside temperature of +10 degrees Celsius and low humidity. Pointing joints better in the morning. Stones hung on the facade of a few seasons and have not fallen. The strength of masonry is shown in the video.

on 1 m² It took 5-6 heater plug-fungi and 10h140 10h160 mm. If you warm up you walls Epps MUST Sand it with a hacksaw on wood with two sides. This will remove the plates with a smooth top layer and to improve adhesion of the adhesive mixture.

2. Why is it dangerous to trim gas and foam concrete stone

I have built a house of aerated concreteD400. Region of residence - Rostov region. I want to decorate the walls with natural stone, sandstone or shell. Have questions:

• How to glue the stone right?
• What use mesh and glue?
• Like a stone on the facade will affect the microclimate in the house, and durability of the walls?
• What will happen to the vapor permeable layers?

Expert opinion FORUMHOUSE

The walls of the house are made of a material with high vapor permeability. Therefore it is impossible to use such an external finish. Otherwise, you get vlagonakoplenie block!

Dimskiy Don

I will be glued to the glue sandstone. Stone has a large vapor permeability than the aerated concrete. The question is not water vapor permeability, and in masonry technology. I need a durable facade. How to do it?

Expert opinion FORUMHOUSE

Water vapor permeability sandstone is lower than that of aerated concrete. If you paste a stone on the gas silicate, the condensation zone is in aerated concrete, stone and will not give moisture to the outside. Moisture will meet on the inner surface of the sandstone. In winter it freezes and starts to tear the block. Therefore, the technology that is not aerated outside trim conventional cement plaster, and special structures for cellular concretes having high water vapor permeability. As an option - make Ventfasad.

Dimskiy Don

Strange. In the SNIP states that water vapor permeability of the sandstone over aerocrete. Or I'm wrong?

You have something to confuse. Sandstone has a lower water vapor permeability than the foam-and aerocrete. If you originally wanted to decorate the house with sandstone, it was necessary at the design stage to think of something better to put under this type of wall finish. In your case, help is only a vapor barrier, mounted on the inside of the house. Or think of an alternative finish.

An important point that many lose sight! When decorating the walls of the stone you mount it on a special adhesive composition, and glue in the system of aerated concrete wall, stonework, works as an additional vapor barrier. This leads to vlagonakopleniyu in cellular concrete.

Summary sums Dmitry Galayuda - Advisor section on ventilation FORUMHOUSE. Nick portal Gaser.

The problem is this. Water vapor from the house goes through the concrete, but can not pass through the stone facing, which is virtually impermeable to him. At low temperatures, the steam condenses, and a frozen moisture tear boundary wall layers of cake. I believe that you can not glue the stone directly on the gas silicate. Or make a vapor barrier on the inside of the house. But then why build the house of aerated concrete?

3.How to stick on the stone walls of gas and foam concrete

Is there a way out of the situation described above? After all, in the south of Russia, often veneer stone house without ventfasadov and do not fall off. In addition, there is a positive experience, and in regions where severe winter.

In Yekaterinburg, there are cold - 40 degrees. Houses, stone-built, a lot. Veneer after plastering. Stone stands and falls.

When you see the beautiful house, decorated with a stone, ask the owner, from which the walls are made. Is there insulation.

Expert opinion FORUMHOUSE

In the southern regions of the house is not insulated. The walls are built of brick. Then drive in the valve is welded to it a metal grid at a distance of 1.5-2 cm and at the same distance, on the "feathers", mounted stones. The gap between the stone and the wall of the mug, polymer solution was poured.

Joni777

Exactly! That is how do we do.

Under the stone facing, lift structurally strong walls with low water vapor permeability. For example, of solid bricks. Then ASSUME galvanized metal mesh. Mesh size - 25h25h1.6 mm or 50h50h2.5-3 mm. Attach it to the anchors driven into the wall. Dowels drive in under the upper bar. Since the grid, under the weight of the stone, not with the time shift down.

And what about the owners of the houses of aerated concrete and cold "boxes" that will be warmed? Make the insulation part of the system wall, stone facing.

I have a house of foam blocks. Willing to insulate its stone wool thickness of 10 cm, a density of 145 kg / m³. Further, through reinforcing mesh, beat dowels. Then glue the stone. So you can do?

Kaser

user FORUMHOUSE

I have a house of aerated concrete. The wall thickness of 375 mm. I want to make wet facade of mineral wool in thickness of 5 cm, and part of the walls to decorate the artificial stone. Stone is heavy. Weighs 64 kg per 1 m². Insulation withstand such weight or better to abandon it?

Recommendations FORUMHOUSE specialists

To answer these questions you need to know exactly what data on gas and foam concrete. In the first case - the thickness, brand, density, who the manufacturer. General recommendations:

• For Dmitry OO. In the foam does not stick mineral wool, polystyrene and the front 25F PSB-S, 15 cm thick. Maybe more, must be considered. Then kleite stone double-base reinforcing layer.

• For Kaser. If you have concrete, brand D500-D600, the plaster and the stone facade ASSUME polystyrene PSB-S 25F. foam thickness - 15-20 cm. Why such a thickness? Since the zone is possible condensation moisture in the insulation and not in the block. By attaching a stone to make sure double reinforcing base.

Blitz-questions and answers on the decoration of the facade stone

Below we have collected information by which you will understand how to glue the stone on the facade.

• How to make a double layer of base reinforcement?

Double reinforcing the base do so:

• Coat the insulation adhesive layer.
• Drown in enhanced adhesive fiberglass mesh, t. N. armored grid density of 320 g / m².
• Through the first base - armored mesh and glue, hammer in the foam plug-fungi with metal nail. Number of dowels - 10-12 pcs. 1 m².
• Dip in adhesive facade alkali resistant glass cloth mesh density of 145-160 g / m².
• Make glue constriction.
• Glue the stone.
• Powertrowel seams.
• To protect from moisture facade cover stone hydrophobizator.

In fact, the weight of the stone on the facade are holding anchors - anchors that are hammered through the mesh and foam in the wall of the house. Recommended stone weight for attaching to front - not more than 50 kg per 1 m². More at your own risk!

• How to combine plaster and stone facades?

Make between facing stone and "wet facade" of temperature and contraction joints, laying the bundle of polyethylene foam and sealant. Node is not necessary to plaster. Decorative frame of PSB-C, with the base layer with the reinforcing grid will close these seams and can not be seen on the facade.

• Why can not stick stone on stone wool?

Mineral wool insulation vapor permeability. Therefore glue the stone only to a thick layer of foam cladding. Otherwise, in the condensation of moisture, mineral wool gets wet under a rock that lead to emergency facade.

The thickness of the insulation layer is calculated according to vlagonakopleniya design.

• How to Lose karkasnik artificial stone?

In order not to lock the moisture in the walls of the frame and allow the couple to go outside, take a hinged facade. Cake design:

• kontrobreshotka;
• OSB-3;
• damping layer - facade 5 cm thick foam adhered to OSB than cement, and polymeric adhesive, ie,.. - adhesive foam;
• dual layer reinforcing base;
• a rock.

conclusions

Finishing with stone home - crucial process. Any mistake will lead to costly repairs. It should be taken into account in advance:

• bearing capacity of the soil;
• lay the foundation with a stock under heavy finish;
• choose the wall material;
• estimate the weight of the stone and the best "pie" of the walls;
• calculate the thickness of the thermal insulation layer.
• calculate the estimate.

The only way you will get the eternal stone facade.
