How and how to glue gypsum decorative stone on the wall

How to properly glue a decorative stone on the wall + the choice of glue

Decorative stone is often used to decorate rooms inside as well as buildings outside.

Thanks to this building material, a beautiful imitation of all natural types of masonry (slate, brick, and also cobblestone) is created.

For the work to be carried out efficiently, the decorative stone must be glued to the wall correctly.

General information

Advantages and disadvantages of decorative stone

The popularity of decorative type panels is due to their excellent properties, the most important of which will be:

• A wide range of colors.
• Light weight.

• Easy to install.
• Ability to recreate the most accurate imitation of masonry material of natural origin.
• Flexural and compressive strength.
• Features of the components that are part of the decorative stones, and make it possible to adjust the indoor climate.
• Resistant to high temperature.

• Long operational life.
• Low cost compared to materials of natural origin.
• Almost any available adhesive will work.

• The factor that is pleasant with tactile contact.

The disadvantage of such a building material is fragility - if you hit it, it will begin to split.

Materials and tools

To independently cover the wall surface with decorative stones, you will need the following tools:

• Building level.
• Rope.
• Saw.
• Roulette.
• Hacksaw.

• Sandpaper or file.
• Drill.
• Long ruler (ideally one or two meters).
• Pencil.
• Spatula to apply the adhesive.

• Brush with metal bristles.
• Roller (or brush) for applying the primer.
• Trowel with a base width of 6 to 8 cm, made of wood, which is intended for grouting.

Next, let us consider which adhesives are best to "plant" a decorative stone.

Adhesives

The quality of adhesion of the surface, as well as the duration of use of the cladding, will depend on how correctly the adhesive is selected.

Installation of artificial stone can be made on the following types of compositions:

• Dry cement mixture.
• PVA glue.
• Acrylic adhesive.
• "Bustilat",
• "liquid nails",
• Adhesive composition for tiles.
• Thickened paint.

• Putty.
• Tile adhesive.
• Mastic.
• Assembly polymer sealant.
• CMC (we are talking about CarboxyMethylCellulose).

Good advice! When choosing a product, be sure to take into account the type of base, how convenient it will be to apply a certain adhesion material and the reputation of the manufacturer.

How to glue decorative gypsum stone on the wall? The most popular brands of adhesive formulations used for facing surfaces with decorative artificial boards:

• Cerisite.
• "Eunice +".
• "Kreps".
• Corian.

• "Acrylic".
• Confiad.
• Litokol.

So, let's look at how to prepare surfaces and materials.

Details

Preparation of materials and surfaces

You can attach plaster tiles to almost any type of surface - concrete, brick or wood walls, plaster, metal and glass.

The main requirement that ensures a quality installation will be dryness, strength and cleanliness of the base.

The surface preparation is as follows:

1. Remove the remnants of the old facing layer - all plaster and old adhesive will need to be removed.
2. Brush the surface of the base with a wire brush.
3. Apply a deep penetrating acrylic primer to the surface. After that, you should leave the walls to dry in accordance with the instructions for priming.

Good advice! If the walls are wooden, then a reinforcing fiberglass mesh should be installed.

Another step will be to prepare the material for facing. Initially, it is required to calculate the area of ​​the cladding. The standard material overrun will be 10%, which should be borne in mind when calculating the required amount of material.

Preparatory stage for the material:

1. Cut the artificial stone into pieces of the required shape and size using a hacksaw or saw.

2. Cut areas should be filed or emery paper to give a natural look.
3. The reverse side of stone slabs should be lubricated with the same primer that was used to treat the wall surfaces. Then leave to dry.
4. Apply paint to the veneer and let dry. Several shades will be required.

Next, consider the direct instructions for use.

Instructions for gluing

So, let's look at how to glue a decorative stone on the walls. For laying decorative stone, two technologies are used - seamless, and also with jointing. The ideal option should be selected even before the installation work begins, so that it is possible to correctly calculate the amount of material.

Please note that with a seamless installation method, the consumption of stone material will increase by 10-15%.

The principle of tiling work is very similar for both technologies:

1. Place on the floor near the cladding site, gypsum tiles (stone of artificial origin) in the sequence as they will be placed on the surface of the walls. This will make it possible to see the final finishing result and make the required adjustments.
2. Mark the surface of the walls to ensure the most accurate placement of materials.
3. Carefully study the instructions for the composition of the glue and only after that you can begin to dilute the solution. This is extremely important because ready-made mixtures have a limited life.

4. Prepare the adhesive composition - it should be free of lumps, not very fluid, thick, but definitely not sticky.
5. If a cement-based mixture is used, then it should be applied to the walls in a layer with a maximum thickness of 0.6 cm. Do not cover more than 1 square meter with glue at a time - to prevent the glue from drying out.
6. Apply a spot mortar to the back of the tiles (8 dots each) or in wave strips if the selected adhesive is a polymeric installation sealant.

7. Begin glueing the decorative stone from the bottom of each corner where it is more convenient.
8. Press each tile into the mortar applied to the walls so that it protrudes around the edges of the part. Press the material to the surface as tightly as possible.
9. If the method of laying with seams is chosen, then it is not necessary to make the gaps between the tiles more than 1 cm. With the technique without seams, the edges of the fragments should be as tight as possible to each other.

10. Fill the joints between the tiles with the special grout or adhesive used for the installation. In certain cases, the adhesive squeezed out along the edges is sufficient to level the surface and seal the seams.
11. Trowel the seams after the adhesives or grout have started to set, but wait until the final hardening of the composition is unacceptable. It should be borne in mind that the approximate curing time for different products can vary from 10 to 30 minutes.
12. The tiled surface by means of panels should be treated with polyurethane or acrylic varnish.

    This will provide reliable protection against moisture, as well as long-term operation. For the same purposes, you can use any product that has water-repellent properties.

13. Complete drying of the surface, which is covered with gypsum tiles, is achieved within 3-4 days.

Good advice! Gypsum decorative stone, which is easy to glue on walls, is a lightweight material, and it is perfectly attached to vertical surfaces. But still, it is better to start gluing the tiles from the very bottom row.

This will make it possible to make the lines as straight as possible with a seamless installation method and prevent individual fragments from slipping.

How to glue on the wallpaper

Despite the relatively low weight, decorative stones are a bit heavy wall covering. For this reason, it is not recommended to glue it over wallpaper. Otherwise, there is a great risk that the gypsum panels will lag behind the walls and collapse. If the design will involve a combination of decorative stones and wallpaper, you will need to leave bare areas under the panels.

It is recommended to mark the surfaces of the walls in advance so as not to glue the places where the decorative type stone will be attached when installing the wallpaper. The surface must be prepared for wallpapering and installing a stone - level it, and also treat it with a primer.

Fastening of a stone of artificial origin is carried out only after the wallpaper has been glued, and not on top of it, but on the left free wall sections.

If you want to mount decorative slabs on walls, the surface of which will be ideally pasted over with wallpaper, follow the instructions:

1. Mark with a pencil on the surface of the walls where you plan to glue the stone, step back 2 cm each and outline the boundaries. The indent is required so that the wallpaper canvases slightly go under the gypsum panels and there are no ugly gaps between the two types of cladding.

2. Use a sharp knife or blade to cut out the outlined fragments and remove the wallpaper in such areas.
3. Prepare a glue solution and attach the boards to the walls according to the instructions.
4. Treat the surface covered with panels with a special varnish.

If, for some reason, you should first mount a decorative stone, and only after the wallpaper, you should use one of two methods:

• Attach to the wall surface all slabs, except for the last, top row. Next, glue the wallpaper, you need to make a spade on the area under the stone.

  Finally, attach the last row of plaster boards.

• Install all the boards, without exception, and the wallpaper should be glued with a margin of 6 cm (depending on the type of wallpaper). After perfect drying with a sharp knife, you need to cut off the excess by running along the joints. The resulting seam should be closed with decorative skirting boards (baguette).

Good advice! If you are using not paper wallpaper, but liquid wallpaper, then a spade under the plates is not required - the joint will already be neat.

Useful tips

A decorative stone looks great without any tricks. But there are several secrets on how to give the final finish a design-like look:

1. The lined surface will look harmonious if the sequence of stacked elements of different sizes and shades is correctly selected. When using slabs of the same size, you must accurately maintain the evenness of the lines vertically, diagonally and horizontally.
2. The maximum level of beauty for finishing is given by trimming corners in individual fragments.
3. Seams should be sealed with care and a special bag or syringe should be used to fill the voids.

   The thing is that the solution that got on the front surface of decorative artificial plates is extremely difficult to clean.

Installation of a stone of artificial origin is simple and does not require significant costs, but the work at each stage should be carried out as carefully as possible. Moreover, you should pay close attention to the compatibility of shades of colors and sizes, and only in this case the finish will please the eye.
