Product benefits

  • Internal and external use
  • To fix tiles over existing tiles
  • High performance
  • Low Dust version (UAE, Leb., Qatar, Oman)
  • Excellent Workability

High performance cementitious tile adhesive (latex modified)

webercol plus is a ready mix cement-based high performance polymer (latex) modified tile adhesive for internal and external use. webercol plus has a strong bonding effect, used for adhering large tiles, or in cases of permanent exposure to high degrees of humidity. It can be used in a damp environment, and is water resistant. The addition of the new Low Dust feature allows a dust reduction by 90% during pouring and mixing of the product! (Feature available in Lebanon, UAE, Oman and Qatar)
The Low Dust effect will lead to:
€- Cleaner working sites
€- Easier and quicker renovation

Instructions for use

Surface preparation

Surface must be clean and free from greasy matters or dust. Substrate 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 plus in the proportion of 5 to 6 liters of clean cool water per 25 kg bag (4 to 4.8 liters for 20 kg). 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 plus evenly on the substrate. Use a notched trowel to have a uniform thickness of 2 to 3 mm minimum.Apply the tiles on the substrate and press them firmly, while making sure that the paste does not slip from the tile sides. webercol plus can also be applied on the back of tiles to ensure full adhesion with all the surface. In case exceptional performance is required, each bag of 25 kg webercol plus should be mixed with 1 liter weberad 225 MB (styrene butadiene latex bonding agent) + 4.75 liters clean water.


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


Apply webercol plus on the substrate by areas of around 1 m² 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 webercol plus. Adjustments to the tiles should only be made duringweber.col plus 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 deco
