ARDEX Grout Booster is a specially formulated, water-based, synthetic polymer grout additive. When mixed with ARDEX cement-based grouts, ARDEX Grout Booster improves adhesion, flexibility to reduce cracking and abrasion strength to avoid powdery grout. It can also be used to assist with reducing staining and for enhancing grout color. ARDEX Grout Booster has been developed in an easy to clean formula; it can be used for internal or external, commercial and residential applications on both the floor and wall. ARDEX Grout Booster is recommended for use when grouting tiles on timber floors or in kitchens, showers and swimming pools. It can also be used in general tiling applications to provide water repellent joints on balconies and external cladding; improved flexibility when fixing to backings subject to movement such as plasterboard, chipboard, plywood; increased elastic properties when fixing to heated sub-floors and to substrates subject to limited moisture movement.
