Ark Tiles Overview
Larsen Professional Fiberflex Semi-Rapid Set+ is a fully flexible, S1-rated, microfibre-reinforced, non-slip, cement-based tile adhesive, classified BS EN 12004 Type C2TES1. This listing is a full pallet of 48 × 20kg bags in grey.
Its semi-rapid setting binder gives a long pot life and open time, followed by rapid strength development, and Larsen's GEL technology makes it a soft, easy-to-use thixotropic adhesive for modern large-format tiles. Larsen recommends it for more demanding areas, including very large-format tiles and external use.
