Indications and advises for the laying of coverings in Natural Stone

Consistency of the surface, which has to be covered
Before installation of the decorative stones for the realization of a wall in stone, check the consistency of the surface to cover that must be suitable for the mounting of the stones (see the instructions on the product used for bonding).

PAINTING: The painting has always to be taken off by roughening the wall or by passing a plastering trowel with notches. For taking off the dust, clean the wall once again very much with water. Apply a consolidation and proceed with the sticking. In case that you have difficulty in taking off the painting (for ex. Marmorino) apply on it a net, like in the procedure “INSULATION” and stick later.

CONCRETE: With a high-pressure cleaner take off all traces of oil, form release agents, dusts, soil, dirt or others. At the beginning of the laying, moisten the surface based on the season and the temperature at the moment of the application.

PLASTER: Check that the surface doesn’t show any phenomenon of “crumbling away“, eventually moisten and then apply the adhesive.

BRICK: Plaster the wall before laying.

INSULATION: You have to check that the insulation is perfectly tied to the wall and at the same time, it has to be suitable to sustain the weight of the wall cladding in stone. In case it is suitable to be covered, a galvanized electro-welded mesh has to be fixed with some dowels with a distance among themselves of maximum 40 cm. Level the surface till the mesh is completely covered. When it is perfectly dry proceed with sticking.

DETERIORATED WALLS: Apply a mesh as indicated in the system „INSULATION“and fix it with dowels, with a maximal distance among themselves of approximately 30 cm.

PLASTERBOARD: You have to check that the structure and the tile are suitable to bear the materials‘weight. Afterwards apply an insulating primer and when it is completely dry you can proceed with the sticking.

Advices for the laying of natural stones for the realization of a wall in stone
In case that the material is dirtied with mortars or plasters, the stones have to be cleaned immediately with a sponge and water. Do not treat the stone with any chemical or acid product.
Use an adhesive suitable for stone materials, which doesn’t stain the stones.
We advise the use of a white adhesive for the clearer wall claddings.
