Weber webercol WP – Waterproof Cementitious Tile Adhesive White (25 kg)

Weber webercol WP is a high-performance, ready-mix cement-based tile adhesive reinforced with redispersible polymer. It is engineered for both internal and external use on walls and floors—ideal for demanding wet and humid environments such as bathrooms, kitchens, staircases, and balconies.

Key Features & Benefits

• Latex/Portland-cement mortar formulation, compliant with ANSI A118.4 and EN 12004 C1T specifications.

• Excellent bonding strength and water-resistance for tile fixtures in challenging conditions.

• “Low Dust” technology version (in UAE, Oman, Lebanon) reduces dust by up to 90% during pouring/mixing—helping with cleaner job sites and faster renovations.

• Thixotropic and non-slip: suited for use on walls and floors, even when tiles are heavy or large-format.

• Suitable for a wide range of tiles—ceramic, porcelain, natural stone (subject to substrate & tile type) and on substrates including concrete, lightweight block work, stone walls, gypsum board, cementitious renders.

Applications & Usage Areas

• Internal walls and floors in residential or commercial settings

• External floor applications (e.g., terraces, balconies) when properly prepared

• Wet areas and high-humidity zones: bathrooms, kitchens, stairwells, parking areas

• Designed for professional tiling installations where durability and performance matter

Technical Highlights

• Mix ratio for 25 kg bag: approx. 5 – 6 litres of clean water. For 20 kg bag (if used) approx. 4 – 4.8 litres.

• Open time: ~25 minutes at 20 °C.

• Service temperature range: –20 °C to +70 °C

• Shelf life: 12 months when stored in original unopened packaging, in a dry condition.

Important Considerations

• Substrate must be clean, sound, free of dust, oil, or loose material; any curing shrinkage should be completed.

• Gypsum plaster substrate is not advised unless properly primed/prepared.

• When using large or heavy tiles, apply adhesive to both substrate and tile back (back-buttering) to ensure full contact and adhesion.

• Grouting should typically be done at least 24 hours after installation.
