BENERFLEX +S1 Extra White High Yield is a powder adhesive consisting of cements, graded particle size aggregates, synthetic resins and special additives. It has been formulated and developed for a rapid, reliable installation of ceramic, porcelain & natural stone tiles, even on non-absorbent substrates and onto substrates subject to slight dimensional variation. Thanks to its particular composition, Benerflex +S1 can be mixed with a higher percentage of water to allow for complete "wetting" of the back of tiles, even on large format tiles, with no need for back buttering.

Laying of porcelain tiles, thin ceramic slabs, non-absorbent single-fired tiles, double-fired tiles, and natural stones (water-stable), even large size, and glass mosaic in:
- Interior and exterior walls and floors
