STOPGAP P141 is an acrylic primer designed to promote adhesion and application characteristics of STOPGAP levelling compounds to non-absorbent subfloors. STOPGAP P141 contains recycled uPVC pulver that dries to a hard, textured surface to enhance bond performance.
STOPGAP P141 is recommended for use over non-absorbent surfaces such as ceramic tiles, treated power floated concrete and STOPGAP waterproof surface membranes.
STOPGAP P141 is recommended when applying STOPGAP 600 over non-absorbent surfaces at thicknesses over 20mm.
It is suitable for use over normal underfloor heating and is pigmented yellow for visual control of coverage uniformity
