Stopgap 1100 Gypsum, a calcium sulphate based smoothing underlayment, Styccobond F46 pressure sensitive acrylic adhesive and Styccobond F41 carpet tile tackifier, from F. Ball have been used for the installation of vinyl sheet safety flooring and carpet tiles as part of the refurbishment of Kingussie Courthouse in Scotland.
Flooring contractors were called to install flooring over an anhydrite subfloor which contained underfloor heating. Before applying Stopgap 1100 Gypsum smoothing underlayment, they primed the subfloor with Stopgap P121 acrylic primer.
Stopgap 1100 Gypsum smoothing underlayment was then applied throughout the area. Applying a cement-based smoothing underlayment over an anhydrite subfloor can cause an adverse chemical reaction which can cause the floor to fail. However, Stopgap 1100 is a specially formulated calcium sulphate based smoothing underlayment which offers excellent compatibility with anhydrite screeds. In addition its self-levelling and can also be used over a wide range of other subfloor types.
Contractors then used Styccobond F46 pressure sensitive acrylic adhesive to install the vinyl sheet flooring, as it is suitable for use over normal underfloor heating systems. Styccobond F46 is a solvent free pressure sensitive acrylic adhesive that dries to a permanent tacky film.
Styccobond F41, a solvent free acrylic polymer emulsion adhesive was then used to fit the carpet tiles. Styccobond F41 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.
Roy Henderson, of A&H Floor Covering Specialists, said: “We always use F. Ball products; we’ve never experienced an issue with them and we know that they will help us to successfully install flooring. We are really pleased that our F. Ball representative recommended that we use Stopgap 1100 Gypsum, Styccobond F46 and Styccobond F41 for the refurbishment of Kingussie Courthouse. It provided the perfect solution for the installation of vinyl tiles over an anhydrite subfloor and underfloor heating.”
