LIFTING old tiles or flooring to lay a new floor can be time-consuming and difficult depending on the adhesive used, and it isn’t always necessary.
Says Tilemaster Adhesives: ‘Where the previous floor consists of sound ceramic or vinyl tiles, it’s a relatively simple task to ensure they’re all firmly stuck down and not cracked or broken, prime them with Tilemaster Prime+ Grip and use a suitable smoothing compound to cover them and level and smooth the floor.’
Tilemaster Adhesives recommends Tilemaster Super Flow 30, which it describes as a double component, ultra-rapid setting smoothing compound that’s ready for laying impervious flooring such as LVT and vinyl after 90 minutes.
‘This has excellent flow and adhesion properties, is moisture-tolerant and can be used to smooth the floor prior to the installation of a damp-proof membrane.’
The company continues: ‘An excellent alternative, where speed is still important but less critical, is Tilemaster Pro Flow. This has many of the same properties as Tilemaster Super Flow 30 with a longer working time. It has a waiting time before laying of four hours for decorative floorcoverings. Both of these smoothing compounds can be used without priming on most substrates, although priming will minimise the risk of pinholes forming, allow for the best flow properties and prolong the working time of the product.
‘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. Again Tilemaster Super Flow 30 and Pro Flow are the products to turn to, as they work well over these residues, providing a smooth surface on which to lay the floor.’
Once the floor is smoothed, Tilemaster Eco-3000HT should be used to install the floorcovering, says the company. ‘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’s ideal for use in conservatories, as well as other buildings with large expanses of glass where direct sunlight may heat the floor. Tilemaster Eco-3000HT 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.’
