Instructions for use

Surface preparation

Substrate must be structurally sound and free from loose tiles and debris, existing setting material or any foreign matters.

Product preparation

Mix the two components of webercol flex FS by pouring the powder in the liquid progressively while stirring the liquid.
An electric mixer with low rotation speed (< 300 rpm) can be used. Mix until a uniform lump free paste is obtained.

Product application

Apply webercol flex FS evenly on the substrate. Use a notched trowel to have the required thickness. Apply the tiles on the substrate and press them firmly, while making sure that the paste does not slip from the tile sides. webercol flex FS can also be applied on the back of tiles to ensure full adhesion on the entire surface.


Clean the tools with water after use. Cured materials can only be removed mechanically.


The mixed webercol flex FS should be used within 15 minutes from mixing time at 20°C.
It is recommended to determine the suitability of all materials before proceeding with the installation
