Preparing the subfloor
Prior to the installation of a smoothing underlayment, the subfloor was mechanically cleaned to remove impurities and two coats of Stopgap F78 one component, rapid drying waterproof surface membrane were applied. Stopgap F78 impedes the passage of residual construction moisture from affecting subsequent floorcovering installations, allowing early installation of floorcoverings in fast track building programmes. Stopgap F78 must be applied in two coats and can be used to isolate residual construction moisture where relative humidity values are up to 95%. It is pigmented blue to allow the user to visually control coverage uniformity.
Smoothing things over
Stopgap 300 HD heavy-duty fast drying self-levelling smoothing underlayment was then applied to the hospital floor. Stopgap 300 HD was particularly suitable for this flooring installation as it is designed for use in areas subject to heavy loads and/or high levels of foot traffic, including hospital floors which commonly have to withstand heavy equipment and a large volume of patients each day.
Sticking to the task in hand
Finally, Styccobond F44 acrylic adhesive was used to secure the vinyl floorcoverings. Styccobond F44 is a solvent free acrylic emulsion adhesive, which is designed to have high initial tack, a long open time and deliver a high bond strength. It is protected against bio-degradation and is suitable for use over normal underfloor heating installations.
