High Flexibility

Applications & Uses

Markets: Building & Construction
Applications: Building & Construction — Flooring & Surfaces
Other Flooring & Surface Applications
Application Area: Masonry
Applications: Use for setting porcelain, glass, quarry, ceramic, all types of mosaic and most natural stone tiles.

Use over exterior concrete and masonry surfaces, as well as over common interior surfaces, including exterior grade plywood.

Extended open time of up to 60 minutes - double the ISO standard.

Especially suited for large format tile installations.

Very high bond strength, highly flexible for excellent shear resistance.

Unique, semi-pourable consistency makes it extremely easy to mix and apply.

Ideal for high traffic areas.

Special additives virtually eliminate the risk of efflorescence.

Use for interior and exterior floors and horizontal surfaces.

Outstanding coverage - 105 sq. ft. (9.75 sq. m) per bag with 1/4″ Sq. Notch trowel.

4 hour pot life.
Coverage: 1/4” x 1/4” (6 mm) sq. notch trowel = 105 ft² (9.75m²) per bag.

1/4” x 3/8” (6 mm x 9 mm) sq. notch trowel = 75 ft² (6.97 m²) per bag.

1/2” x 1/2” (12 mm) sq. notch trowel = 50 ft² (4.65 m²) per bag.

Coverage varies with texture of substrate surface.
Water Ratio: 6 3/4 - 7 1/2 quarts (6.25 - 7 L) of clean water per bag; or.

2 1/4 - 2 3/4 parts powder to 1 part water by volume (small batches).
