Description
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.
3. INSTALLATION
We recommend starting the installation from the floor to the ceiling, continue in phase to allow the adhesive the necessary time to get dry. Extend a thin layer of adhesive onto the surface where the piece will be installed (3mm approx.) Then, use a notched trowel no. 3 to make incisions into the adhesive layer. Place the piece while the adhesive is still soft and before a dry layer of film forms on the adhesive surface. To install 30×60 pieces or similar, extend a thin layer of adhesive on the surface where the piece will be installed (vertically) and another layer on the back of the piece itself, in the opposite sense (horizontally). Then, use also a notched trowel no. 3 and make the incisions into both the adhesive layer of the wall and in the opposite sense in the piece. Do not use dot setting or dab the adhesive during installation. Once the piece is placed, press carefully to obtain correct adhesion and cover possible areas without adhesive.
