Product Description
PALACE Super-Flex S2 Grey is a single-part, polymer-modified, cement-based tile adhesive designed for demanding installations where movement, vibration, or thermal change is expected.
Its rapid-setting formulation allows foot traffic and grouting to proceed just 4 hours after fixing, making it ideal for fast-track commercial and domestic projects. The advanced fibre-reinforced technology (RFT) provides excellent flexibility and adhesion strength, even on difficult substrates.
Suitable for fixing ceramic, porcelain, mosaics, and vitrified tiles, PALACE Super-Flex S2 performs exceptionally on heated subfloors, plywood overlaid with tile backer boards, tongue & groove floorboards, and stabilised floating floors.
Conforms fully to EN 12004 – C2FTE-S2 classification.
