REDIFIX Tile Adhesive Additive is an acrylic based polymer additive to ABC Tile Adhesive Original. It makes indoor & outdoor non-concrete tile installations possible such as tile-over-tile, tiling on wood, metal, gypsum & fiber cement board and marble & granolithic flooring. Redifix adds flexibility without compromising the adhesive’s bonding strength. How to use Surface Preparation The surface must be fully cured, structurally stable, level, even, clean and free of paint & contaminants such as dirt, dust, loose material, oils and chemicals. The use of a level bar is essential to ensure levelness and / or plumbness of the surface. For painted surfaces, acid etch or abrade paint to ensure proper bonding. How to use Redifix Caution: Use only non-absorptive materials as mixing base (plastic pail or G.I. sheets). If absorptive materials such as plywood, wooden box, gypsum board, fiber cement board or cardboard is used, it will affect the chemical properties of the product, which can result in bonding failure and poor product performance. REDIFIX as Slurry The slurry provides a rough surface enabling tile adhesive to adhere to non-concrete surfaces.
