Consistency of the surface to cover
Before installation, 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 an 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 an 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 stone wall cladding. 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.
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 application.
Laying of the wall claddings
Prepare the necessary material.
Prepare the adhesive by following the indications of the producer.
Spread the adhesive on the wall.
Level the wall with the spatula with tooth.
Prepare the starting by using e level and wedges
Go on with the bonding of the wall cladding, by using the level for checking the exact positioning of the piece.
If necessary cut the piece with a water-blade saw with a blade for stones and marbles.
Realization of a 45 degree angle
Shape the pieces by cutting it with a water-blade saw with a blade for stones and marbles.
Realization of a 90 degree angle
Compose the angle by alternating the borders
Advises for the laying of line Tekna
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.
