High strength flexible tile adhesive.
For dishing-prone resin-bonded tiles, cast stone and terrazzo tiles, earthenware, stoneware and fully vitrified stoneware tiles, mosaic, terracotta, discoloration-resistant natural stone units in marble, granite, etc. Also suitable as bonding and contact layer in conjunction with thick-bed method, e.g. for rapid-set mortars incorporating Sopro Rapidur® B1 turbo binder. Suitable for commercial and industrial facilities, hospitals, public buildings, airports and railway stations.
Sopro VF HF 420 ensures full rear-face wetting of tiles, exceptionally high frost resistance for covering system and uniform load transmission to substrate. Suitable for trouble-free laying of large-format fully vitrified stoneware tiles up to 1 m² in size on calcium sulfate screeds pre-treated with undiluted Sopro GD 749 primer. For larger formats, calcium sulfate screeds should be pre-treated with Sopro MGR 637 multi-purpose primer or Sopro EPG 522 epoxy primer.
An extra-rapid-set, early-high-strength, flexible, cementitious floating-bed tile adhesive allowing early loading, for efficient tile laying and is particularly suitable for dishing-prone resin-bonded tiles using a thin-bed method. Low-chromate to Regulation (EC) No 1907/2006, Annex XVII. Tested to C2 EF, DIN EN 12004.
