Instructions for use

Surface preparation

Substrate must be clean and free from greasy matters or dust. It should have been sufficiently cured in a way that any shrinkage has already occurred. Moisten slightly the substrate if it is dry at the time of application, never moisten the tiles.

Product preparation

Mix webercol fix in the proportion of 5 to 6 liters of clean cool water per 25 kg bag (or 20 kg with 4 to 4.8 liters of water). An electric mixer with low rotation speed (< 300 rpm) can be used.
Mix until a uniform lump free paste is obtained. Let the paste rest for a few minutes before starting the application.

Product application

Apply webercol fix evenly on the substrate. Use a notched trowel to have a uniform thickness according to the size of the tile.
Apply the tiles on the substrate and press them firmly,while making sure that the paste does not slip from the tile sides. webercol fix can also be applied on the back of tiles to ensure full adhesion on the entire surface. In case exceptional performance is required, each bag of 25 kg of webercol fix should be mixed with 1 liter weberad 225 MB (styrene butadiene latex bonding agent) + 4 liters clean water. For 20 Kg bag webercol fix, use 1 liter weberad 225 MB +3 liters of clean water.


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


Apply weber.col fix on the substrate by areas of around 1m² each, which can be tiled within a maximum of 15 minutes from application time at 20°C. After that time, an outer skin may form thus preventing the tile from adhering properly to weber.col fix. Adjustments to the tiles should only be made during its open time.
It is recommended to leave a minimum width of 2 mm around the tiles (or as designed). Grouting the tile joints should only be done at least 24 hours after tiling, using weber.joint perfect or weber.joint (Carrojoint).

The product contains cement powders which, when mixed with water, release alkalis that could be harmful to the skin. It is preferable that the application be done in a ventilated area, and to wear protective gear for hands, eyes and respiratory system and to avoid breathing of the dust. Splashes on the skin should be washed away by cleaning thoroughly with soap and water. In case of contact with eyes, wash thoroughly with clean water and seek medical attention. If swallowed, do not induce vomiting and seek medical attention. The product is non-flammable.
