Step by step solution
Tiling on terraces over a sand bed
Apply 2 layers of weberdry 210 AFC or weberdry gum, an acrylic waterproof membrane, between the substrate and the sand bed. After 24 hours minimum, fix the tiles with webercol floor, a thick adhesive mortar applied above the sand bed.
Concrete substrates - Tile adhesive
webercol flex, webercol max, webercol fast, webercol F1, webercol plus are particularly adapted to this kind of application. In case of large white tiles or stones, webercol fast or webercol F1 can be used.
The back-buttering method is mandatory (adhesive applied to the substrate and on the back of the tile) to ensure full adhesion between the tiles and the substrate and to avoid voids in the adhesive layer. Apply the tiles and press them firmly ensuring a good adhesion between the tiles and the substrate.
It is recommended to have a minimum joint width of 2 mm around the tiles.
Grouting should be done at least after 24 hours of fixing tiles (after 3 hours only when using webercol fast or webercol F1).
Use weberjoint perfect, a low water-absorption grout with Hydro Repell® and Mould Stop® technologies, should be used or weberepox easy, an epoxy based tile grout.
