Gorsey Bank School, Cheshire

Stopgap 700 Superflex excels at school

Flooring contractors faced with timber beams infilled with insulation and overlaid with plywood, used Stopgap 700 Superflex smoothing underlayment to provide a surface suitable for the installation of carpet tiles. The project was a new wing for the Gorsey Bank Primary School in Wilmslow, Cheshire.

The timber joists overlaid with plywood were used over the structural floor slab, which was then brought to a smooth surface through the application of Stopgap 700, a flexible, fibre-reinforced smoothing underlayment.

Stopgap 700 is designed specifically for use over plywood subfloors, which have a potential for limited movement over time. Should cracking occur as a result of such movement, the fibres keep the underlayment integral. It also incorporates the latest Ultra Fast Drying Technology which means the underlayment is walk-on hard after just 60 minutes and allows new floorcoverings to be installed in as little as 3 hours.

The plywood was first treated with Stopgap P131 primer then Stopgap 700 was applied to a depth of 3 – 10 mm as required. Finally, Styccobond F41 carpet tackifier was used to secure Heckmondwike carpet tiles to four classrooms and corridors – some 500m² in all.
