F Ball & Co and Dumfries & Galloway hospital pharmacy

F BALL & CO’s high performance smoothing underlayment, Stopgap 1200 Pro, provided the solution during the refurbishment of Dumfries and Galloway hospital pharmacy.

The smoothing underlayment was specified to provide a professional flooring solution for a residue-contaminated subfloor creating a durable, high quality floor finish, without the need for priming or mechanical removal of the residue.

On removal of the old floorcovering and the results of a moisture measurement test concluding the subfloor was suitably dry to proceed, contractors at A&H Floorcovering Specialists discovered the surface was contaminated with asbestos tile adhesive (ATA). This restricted their ability to mechanically prepare the subfloor.

Proving an ideal solution to the challenge, contractors could completely cover the firmly bonded adhesive with an application of Stopgap 1200 Pro.

The smoothing underlayment from F Ball has been formulated for direct application over waterproof surface membranes and old adhesive residues, without the need for priming, and offers a cost effective, time-saving solution for the flooring contractor.

A 3-4mm layer of Stopgap 1200 Pro was applied over the 160sq m area. Utilising the latest cement technology, the latex-free smoothing underlayment is said to achieve fast-setting and drying times for preparing sound internal subfloors.

With a working time of 20 minutes, and a walk-on time of just 60 minutes, the pharmacy was ready to receive its new vinyl floorcovering after only four hours.

Suitable for various flooring installations, Stopgap 1200 Pro can be used over a range of subfloor types, such as sand/cement screeds, concrete, terrazzo, asphalt and ceramic tiles.
It’s also suitable for patch filling timber floors prior to overlaying with plywood.

Following installation of the underlayment, Styccobond F46 was used to adhere the vinyl floorcovering. This solvent free, pressure sensitive adhesive has a high-bond strength and minimises the effect of trowel serrations shadowing through the vinyl floorcovering for an aesthetically pleasing finish.

Commenting on Stopgap 1200 Pro, Roy Henderson of A&H Floorcovering Specialists, said: ‘Stopgap 1200 Pro was an excellent product to work with, and provided us with the speed and ease we were looking for with this challenging installation.

‘The product had excellent self-smoothing properties and produced a professional finish, which was particularly impressive considering the little work it needed – I’d thoroughly recommend it.’
