How to glue and grout decorative wall cladding with gneiss stone

The cladding with gneiss stone Ivaylovgrad gives a natural radiance of beauty and style to each wall. This is a suitable choice for lining entire walls, as well as parts of them, to achieve original decorative solutions.

Ways of fastening gneiss plates

When facing with natural stone, such as gneiss from Valmarg Stone , two ways of fixing the slabs are used – with mechanical fastening and with gluing. The choice between the two methods depends on how large the tiles or other elements of the cladding are. It is very effective to line with bones – thin pieces of gneiss material, and for their attachment it is necessary to use glue. 

If you deem it appropriate, you can combine the two methods of fixing gneiss boards and other elements.

Requirements for the adhesive when gluing gneiss plates and bones

For natural materials, such as gneiss from Ivaylovgrad , the adhesive used must be flexible. This is important in order to be able to maintain the fastening of the cladding in case of thermal expansions, especially when cladding external walls. 

Adhesives designed for ceramic coatings are recommended for exterior cladding. They have the necessary flexibility and high resistance to sudden changes in weather conditions.

To make sure that the cladding will be firmly attached, choose a quality adhesive.

Preparation of the adhesive for gluing the cladding

The glue must be prepared in a suitable container. It must be mixed with water. You can more easily achieve even mixing by using an electric mixer. If you do not have one available, mix well so that the mixture is homogeneous and therefore good adhesion will be obtained.

Facing slabs or bones Ivaylovgrad gneiss , as well as the base – the wall to be lined, must be covered with a layer of glue and then begin gluing. Gradually line the wall, preparing small sections of the wall and several plates on which a layer of glue is applied. 


First, attach the tiles for which you will not use glue

If you are going to mechanically fasten some of the tiles, fasten them first, and then start gluing the other tiles. The mechanical fastening is suitable for niches.

Filling the joints between the tiles

You must first wait for the adhesive to dry completely before filling the joints.

The grout must be flexible in order to prevent water from penetrating deep into the joint.

Prepare the grout according to the instructions on the package. After mixing with water, it is usually waited for a few minutes, after which the mixture is stirred again.

The mixture is applied in the joints with a steel spatula. Choose a spatula that is slightly narrower than the width of the joints.

After smoothing the surface of the mixture in the joints, smooth completely using a wet sponge.

If desired, you can varnish the joints.

Both gluing the tiles and grouting must be done from top to bottom

An important rule for achieving quality gluing of gneiss boards and grouting is to glue and grout from top to bottom. This will not stain the bottom of the cladding.
