Stopgap Fast Track 30, Rapid Setting Smoothing Underlayment

Stopgap fast track 30 is a rapid setting and rapid drying, self-levelling smoothing underlayment that incorporates the latest advances in cement technology providing a truly fast-track solution. It is suitable for use in light to heavy-duty applications for preparing sound absorbent and non-absorbent subfloors prior to the installation of new floorcoverings, such as both textile and resilient floorcoverings to be installed from as little as 45 minutes at 20°C.

Stopgap fast track 30 is suitable for use over a wide range of subfloor types including stopgap waterproof surface membranes, sand/cement screed, concrete, calcium sulphate (e.g. anhydrite), granolithic, terrazzo, epoxy and polyurethane resins, ceramic and quarry tiles.

A 25kg bag of Stopgap fast track 30 powder mixed with 4 litres of clean water will cover approximately 5.6m² at a thickness of 2mm

Standard mix – Add 4 litres of clean water into a mixing bucket and gradually add all the powder whilst stirring with a power whisk fitted in an electric drill until a smooth creamy lump free consistency is achieved. The material should be mixed for a minimum of 2 minutes.

Area Coverage Per Unit

When mixed with 4 litres of clean water.

5.6m² at a thickness of 2mm

2.2m² at a thickness of 5mm

1.1m² at a thickness of 10mm

Note: Coverage rates will depend on the condition and
absorbency of the subfloor.


It is essential to prime all surfaces.

Absorbent surfaces – Prime with dilute Stopgap P131 to prevent rapid drying of the underlayment. For dry (<75% RH) and suitably prepared anhydrite screeds use neat Stopgap P121.

Non-absorbent surfaces – such as flat firmly bonded minimal adhesive residues, terrazzo, quarry tiles and waterproof surface membranes should be primed with neat Stopgap P131 to ensure that good adhesion is obtained between the underlayment and substrate.

    Exceptionally pleased with flooring. Exactly as expected – even better in fact! Downside packaging was damaged and corners/ ends of carpet exposed.

    Easy to order, customer service was 5*. Had difficulties with delivery due to the weight and driver (sub contracted) not being correctly equipped. This was resolved with re delivery two days later.
