Safety flooring - F Ball
PRODUCTS from F Ball & Co, the UK's manufacturer of flooring adhesives and floor preparation products, have been used to install vinyl safety flooring at the Great Western Railway train depot in Penzance.
A combination of Stopgap F77 waterproof surface membrane, Stopgap F78 waterproof surface membrane, Stopgap 1200 Pro levelling compound and Styccobond F46 vinyl adhesive were used to create what’s being described as an aesthetically-pleasing floor finish.
Contractors from Contract Flooring in Cornwall were subcontracted to install 400sq m of flooring in the newly built depot, which is being used to house sleeper trains, which will run from Penzance to London.
Contractors conducted a moisture test on the flooring and found the moisture levels to be higher than 75% relative humidity, and therefore, the application of a waterproof surface membrane (WSM) was required.
In order to combat the excess subfloor moisture, which can cause extensive damage to floorcoverings and lead to costly remedial work, contractors used a combination of Stopgap F77 and Stopgap F78 WSMs, in areas of varying moisture levels.
When dealing with serious cases of subfloor moisture, with RH levels of up to 98%, F Ball recommends the use of Stopgap F77, a solvent-free two-part, one coat, WSM. Stopgap F77 impedes the passage of residual construction moisture and rising damp from affecting subsequent floorcovering installations, allowing early installation of floorcoverings in fast-track building programmes.
When facing time pressure, water-based moisture management systems, such as Stopgap F78, can be used to isolate residual construction moisture where RH values are up to 95%. Stopgap F78 is a solvent-free, one component, ready-to-use system which dries rapidly to provide a WSM.
Stopgap 1200 Pro levelling compound was then applied over the area. Stopgap 1200 Pro is described as a fast-setting, minimal preparation two-component levelling compound, designed for use over a wide range of subfloor types. It’s suitable for use over old adhesive residue, including bitumen and carpet tile tackifiers, without the need for priming, and can also be used in clinical and biologically sensitive areas such as hospitals, making it the obvious choice for this installation.
In as little as four hours, Stopgap 1200 Pro is ready to receive floorcoverings, so contractors were able to return a short time later to install the new flooring in the depot. Using Styccobond F46, a solvent-free pressure sensitive acrylic adhesive, contractors installed Altro Reliance 25 safety flooring.
John Hudson, managing director of Contract Flooring, commented: ‘We always use F Ball products and often work very closely with our local F Ball representative. We’re very pleased to say, as expected, the range of F Ball products we used on at the Great Western Railway depot enabled us to create an aesthetically pleasing, durable floor finish of vinyl safety flooring.’
