TOPGAP 500 is a rapid drying floor finishing compound providing a smooth surface to plywood, existing floor smoothing underlayments, sand / cement screeds, calcium sulphate screeds and other rigid dry absorbent surfaces, prior to the installation of floorcoverings.
STOPGAP 500 is dimensionally stable and is supplied as a pre-blended dry powder, which is designed for Micro-Coat application to a feathered edge. It is protein-free which allows it to be used in biologically sensitive areas.
Subfloors of plywood / hardboard construction must be securely screw fixed in accordance with local standards.
An 8kg unit of STOPGAP 500 mixed with 4.5 litres of clean water will cover approximately 8m2 at a thickness of 1mm.
