REFURBISHMENT TOP FORM
The experts at Kerakoll explain how to achieve a perfect finish over an old floor.
on top of the surface. Proflow MVS is a highly flexible double component smoothing compound that has all the attributes of a high-performance smoothing compound, but with the added MVS capability that works to block the passage of moisture from the substrate. Proflow MVS is rapid setting and drying, allowing foot traffic after 90 minutes and floorcoverings to be applied after four hours.
Where the existing floor has had to be lifted, adhesive and flooring grade bitumen residues are often left behind, and many smoothing compounds cannot be used over these. Proflow MVS is an exception to this rule, working well over these residues.
It can also be used over asphalt, existing vinyl and ceramic tiles as well as calcium sulphate and sand/cement screeds, and concrete. The biggest advantage of Proflow MVS is due to its innovative new formula, which makes it an MVS (moisture vapour suppressant), allowing it to replace the use of a damp proof membrane or MVS liquid, and making installation smoother and more rapid by combining a potential three applications into one.
Lifting old tiles or flooring to lay a new floor can be time consuming and difficult depending on the adhesive that was originally used, and it is not always necessary. Where the previous floor consists of sound ceramic or vinyl tiles, it is a relatively simple task to ensure that they are all firmly stuck down and not cracked or broken, prime them with Active Prime Fix and use a suitable smoothing compound to cover them and level and smooth the floor.
Kerakoll UK recommends Proflow MVS which has been specifically developed to give a superb surface finish with a prolonged working time allowing resilient floorcoverings to be laid directly
Once the floor is smoothed, Eco-3000 HT should be used to install the floorcovering. This high temperature universal adhesive is suitable for installing LVT, PVC, vinyl flooring as well as carpet and textiles onto a wide variety of substrates. It is ideal for use in conservatories, as well as other buildings with large expanses of glass where a high degree of temperature changes could be expected. Eco-3000 HT has been formulated with a fast tacking-off time. Flooring can be installed after as little as 10 minutes, when the adhesive is semi-tacked off and has reached its ‘anti-slide’ state.
