1. PROPER PREPARATION OF SURFACE
The wall must be firm, leveled, dry, and clean. Uneven surfaces greater than 2mm must be leveled with specific products. All cracks and imperfections should be repaired so that the wall is completely smooth. The moisture content of the surface must be under 2%.
2. INSTALLATION MATERIAL
For a correct installation, several factors must be taken into account: Material kind of the wall to be tiled (synthetic pannels, plaster, wood, etc.), wall stability, environmental conditions, kind of surface to be covered, speed of carrying the work, etc. All the above parameters determine the choice of the adhesive kind. All the adhesive materials recommended by DUNE have been previously tested in our facilities, in controlled environmental conditions, and on rigid brick and/or concrete walls. Under different conditions from the above mentioned, it is recommended to test first, and if in doubt, please contact DUNE or the adhesive distributor. White and Red body wall tile: C1 concrete glue. (Consult adhesives table). Stoneware and porcelain tile: C2 concrete glue. (Consult adhesives table). DUNE always recommends testing first the material with a minimum of two pieces before placing all the material.
