Applications
- Installing large-format ceramic tiles, homogeneous tiles, natural stone, granite, etc.
- Tiles with extremely low water absorption or mesh-backed tiles — two-component application (with additive liquid or bonding slurry)
- Interior/exterior wall and floor tiling, suitable for water-retaining structures such as water tanks and swimming pools
- Direct tiling over cementitious waterproofing materials
Advantages
- Ultra-high bond strength — tensile bond strength after initial curing, water immersion, heat ageing and freeze-thaw cycles
- Extended open time — more relaxed installation
- Slip and sag resistant — slip ≤ 0.5 mm, deformability class S1 (with additive liquid), suitable for large-format tiles
- Efflorescence and mould resistant — prevents salt efflorescence, no mould growth, maintaining appearance
- Eco-friendly and safe — low VOC, non-toxic, complies with drinking water contact standard (BS 6920)
- System compatibility — recommended with Ardex Scoretech renders and grouts for best anti-efflorescence results
