PROBOND® PR220 Gritty Primer

a ready-to-use, fast-drying primer designed to improve adhesion on smooth, non-absorbent substrates, including flooring-grade asphalt, bitumen, existing vinyl tiles, and ceramic, porcelain, or natural stone finishes. PROBOND PR220 creates a textured, high-grab surface, providing a reliable base for tile adhesives and smoothing or levelling compounds when working over dense substrates. With rapid drying, tiling or levelling can typically begin after around 15 minutes, subject to site conditions. Suitable for internal and external use, Gritty Primer is primarily intended for non-porous substrates but can also be used on porous surfaces where improved surface stability is required.
