F. Ball helps infection control at London hospital

Products such as Stopgap 300 HD levelling compound and Styccobond F46 pressure sensitive adhesive, have been used to create a high-quality flooring finish as part of the transformation of a former car showroom into a sterile and decontamination unit for the Royal Free London NHS Foundation Trust.

Flooring contractors were called to install a combination of vinyl sheet and safety flooring over a total area of 3000m2.

The subfloor preparation process commenced with the scabbling of the subfloor to remove layers of paint that were present. A moisture test was then carried out to ascertain moisture levels within the building’s concrete substrate, and it was determined that subfloor relative humidity (RH) levels were greater than 75%. Therefore, Stopgap F78 a one-component waterproof surface membrane was applied in two coats, to provide a barrier against moisture attacking adhesives and floorcoverings, potentially causing floor failure.

Stopgap 300 HD levelling compound was then applied to provide a smooth, hard-wearing base for the receipt of new floorcoverings. Possessing the property of being protein-free, the product is ideal for use in biologically sensitive settings, such as hospitals.

Having completed the subfloor preparation, contractors installed Polyflor safety vinyl sheet and Polyflor Mystique PUR vinyl sheet using Styccobond F46.

As part of the installation, floorcoverings were capped and coved at all wall junctions, helping to create both a neat and practical finish. The welding of seams up to the wall junction ensures a watertight seal, preventing ingress of water, an essential requirement in a healthcare setting which will be subject to extensive cleaning.

Patrick Fay, Contracts Manager at Fay Flooring Ltd. commented on the project: “The project initially appeared to be quite a challenge but with advice from the local F. Ball tech rep and their products, the job was straightforward and completed to a high standard. We use F. Ball products exclusively as they’re reliable, easy to use, and the manufacturer guarantees them.”
