ALPHA is a fast-setting, high-performance, polymer-reinforced sanded grout. This formula, exclusive to PROFIX, is a highly resistant grout which is ideal for most installations. This efflorescence-free grout provides clear colour as well as water and stain resistance that is superior to traditional grout. ALPHA can be used for joints from 1/16" to 1" (1.6 mm to 2.5 cm) wide. It is designed for grouting ceramic tile, porcelain, slate, granite, sandstone or clay tile, paving bricks and stones of various shapes or agglomerated stone. It meets and exceeds ANSI A118.7.
