Everything you need to know about Larsen Fibreflex Rapid Set+ tile adhesive

Larsen Fibreflex Rapid Set+ is a fully flexible, fibre-reinforced tile adhesive classified to BS EN 12004 as C2FS1 — an improved, fast-setting, S1-deformable cementitious adhesive. It's formulated for high performance on demanding substrates, with a bed thickness range of 3–20mm for both wall and floor applications.

It's suitable for fixing a wide range of tiles including ceramic, porcelain, fully vitrified, marble, natural stone, glass and mosaic tiles, and is especially recommended for use over underfloor heating systems, overboarded timber floors and in wet environments such as swimming pools.

With a fast setting time, tiles can be grouted after just 3 hours, helping to speed up installation on fast-track jobs without compromising on bond strength or flexibility.

Supplied in 20kg bags in grey or white, Larsen Fibreflex Rapid Set+ is the quicker-turnaround counterpart to Larsen Fibreflex Standard Set+, giving tilers a fast-track option from the same range when project timelines are tight.
