Universal Primer is a rapid drying solvent-free low VOC water-based acrylic primer. For use over porous and non-porous substrates such as ceramic tiles, painted surfaces (water-based only) and sealed or burnished concrete floors. For extremely non-porous, hard and tight substrates, a light grind or sand should be conducted to enhance adhesion. Universal primer is compatible with cement-based ceramic tile adhesives and levelling compounds.
