Subfloor preparation products and adhesives from F. Ball

and Co. Ltd. have helped deliver style and performance at the world's largest museum of design, the V&A in London.

As part of a refurbishment ahead of the V&A museum’s reopening following the lifting of lockdown restrictions, contractors from Coyden-based Olivers Contracts Ltd were subcontracted by MCD Heritage to install a range of floorcoverings in employee welfare areas, including changing rooms and a canteen, as well as offices and connecting corridors,

Upon arrival on site, contractors found that old floorcoverings had already been removed, meaning their first task was to prepare the exposed screed by removing loose materials and excess old adhesive residues by mechanical means.

A moisture test was then conducted to determine the requirement for a moisture management solution; the use of a hand-held protimeter indicated low levels of subfloor moisture everywhere apart from a corridor off which locker rooms are located. Further testing using a digital hygrometer indicated that subfloor relative humidity levels exceeded 90% in this area, meaning that a waterproof surface membrane would be required to prevent moisture attacking floorcoverings and adhesives, potentially causing floor failure. Contractors therefore applied F. Ball’s Stopgap F77 solvent- free two-part epoxy resin waterproof surface membrane, which isolates residual construction moisture or rising damp where subfloor relative humidity levels are up to 98%, with a single application.

When contractors returned to complete the subfloor preparation, the area where the waterproof surface membrane had been applied required priming to promote the adhesion of a levelling compound. For this purpose, F. Ball’s Stopgap P141 primer was chosen because it is designed to promote the adhesion of levelling compounds to non- absorbent surfaces, such as waterproof surface membranes.

F. Ball’s Stopgap 1200 Pro levelling compound was then applied at a thickness of 6mm in all areas to create a perfectly smooth base for floorcoverings. The product is a fast-setting, fast-drying levelling compound for preparing sound internal subfloors. It can also be applied over old adhesive residues, in which case there is no need to prime subfloors beforehand.

Different floorcoverings were then installed in different areas. Bolon woven vinyl tiles were installed in locker rooms

and changing rooms using F. Ball’s Styccobond F41 carpet tile tackifier, which can be used to secure a wide range of dimensionally stable ‘lay flat’ carpet tiles backed with bitumen/ felt, non-woven fabric, PVC and other polymer backings. The solvent-free acrylic polymer emulsion adhesive is designed to provide a permanently tacky film which prevents ‘loose-lay’ carpet tiles from moving under normal traffic but enables them to be lifted and replaced easily when required, such as when worn or stained. Styccobond F41 was also used to install carpet tiles in the offices as part of the project.

In the canteen dining area, endgrain wood blocks were adhered using Styccobond B95, a one-part, flexible, moisture- curing adhesive that is designed to accommodate the natural movement of wood over the lifetime of floorcoverings. It is solvent and isocyanate-free, quick to develop a high bond strength and provides good grab, an advantage for contractors creating the parquet design.

Contractors used F. Ball’s Styccobond F54 to install Forbo Marmoleum sheet in the corridors and canteen kitchen. A safer alternative to traditional gum spirits for installing linoleum floorcoverings, and offering greater moisture resistance, the solvent-free emulsion adhesive is non- flammable and protected against bio-degradation. It also provides instant grab, reducing sliding of the linoleum and facilitating the installation process.

In the bathrooms, Forbo Surestep safety flooring was installed using Styccobond F46, a pressure sensitive vinyl adhesive, which provides high initial grab to hold floorcoverings in place while working and during the initial stages of drying. This work was completed by fitting Gradus capping and coving at the intersections of floorcoverings and walls using F. Ball’s Styccobond F60 contact adhesive to produce a neat finish and allow for easy cleaning.

Commenting on the project, Steve Lampkin, Director of Olivers Contracts, said: “Everything went according to plan, and there were zero problems or snagging issues. Fast-track products meant that work could be completed quickly, in stages, allowing access to other trades when required, so the entire project could be completed on time.” FEATURE | 35
