Step by step solution
weber solution

Substrate preparation
Substrate should be dry and free from dust or any traces of old materials that could impede a good adhesion with the stones.
In case of tiling over existing tiles or coatings, check their adherence and repair any hollow areas or replace de-bonded tiles.
In case of a very porous substrate (a water drop absorbed in less than a minute) or very smooth surface, apply the primer webercol prime using a brush or a roll.

Tile adhesive
Apply a white adhesive webercol flex, webercol max, webercol F1 or webercol fast using a suitable notched trowel, adapted to the size of the stones and the flatness of the substrate.
For large size stones and on substrates presenting defects in flatness, back-buttering is recommended (tile adhesive on the substrate and on the back of the stone).
Exert a strong pressure on the stones or use a rubber hammer to remove air and ensure a good transfer.
During application, carefully eliminate all traces of adhesive on the face of the stones with a wet sponge.

Stone grouting
Before grouting, wait at least 3 hours after application of webercol fast or webercol F1 (fast-setting adhesives) or at least 24 hours when using a normal setting adhesive.
We recommend weberepox easy for joint from 1.5 to 10mm and weberjoint perfect or weberjoint deco for joints between 1,5 and 20 mm.
The fineness of the grout particles reduces the risk of surface scratching the tile. weberjoint perfect is the right product to grout polished marble and any tiles with a soft surface.
