Weber Col Flex Tile Adhesive
Two components high performance cementitious flexible tile adhesive (Latex modified)
Webercol flex is a two-component cement-based polymer modified, flexible, waterproof tile adhesive for internal & external use. It is a ready mix powder containing cement, siliceous sand and additives. Webercol flex has outstanding qualities such as high bonding strength, high resistance to water and chemicals, water tightness and flexibility. It is used internally and externally with a wide range of small to large tiles, and in cases of permanent exposure to high degrees of humidity.

Apply Webercol flex on the substrate by areas of around 1m² each, which can be tiled within a maximum of 25 minutes from application time at 20°C. After that time, an outer skin may form thus preventing the tile from adhering properly to col flex. Adjustments to the tiles should only be made during weber.col flex’s open time. It is recommended to leave a minimum width of 2 mm around the tiles. Grouting the tile joints should only be done at least 24 hours after tiling, using Weberjoint perfect or Weberjoint (Carrojoint). For immersed areas, allow 21 days curing for Webercol flex before filling with water. Clean the tools with water after use.
Webercol flex can be stored for 6 months in dry conditions, away from extreme temperatures and protected against wind.
