The main difference is the "Pot Life" (working time). A standard rapid set goes off in about 40 minutes. BritFlex S1 Semi-Rapid gives you a 2-hour pot life, making it ideal for large format tiles or complicated cuts where you need more time.
Yes, BritFlex S1 is frost-resistant and suitable for both interior and exterior locations. For external patio slabs, we recommend using a solid bed method (100% coverage) to prevent water gathering under the tile.
Yes, it is suitable for pre-strengthened wooden floors. The "S1" classification means it is deformable, allowing it to absorb the slight vibrations and movement inherent in timber substrates.
It is designed for a bed thickness of 3mm to 12mm, which helps in accommodating slight unevenness in walls or floors while maintaining a strong bond.
Absolutely. It is compatible with both matted and piped underfloor heating systems. The polymer-modified formula allows the adhesive to expand and contract with the thermal changes without cracking.
A 20kg bag will cover approximately 5 sq.m at a 3mm bed depth. However, for large format tiles or uneven floors where a thicker bed is needed (e.g., 6-10mm), the coverage will be reduced.
