When under time pressure, it is essential to use a system that will allow rapid completion without cutting corners, safe in the knowledge that the installation will not fail. Fortunately, the Tilemaster Rapid System allows project completion, including grouting, in around 4 hours which is advantageous when time is of the essence. The stresses on a tiling installation caused by underfloor heating should not be underestimated and adhering to correct installation methods is very important.
Rapid Level 30 should be used to smooth and level the substrate before tiling. This water-based, ultra-rapid setting, flexible self-levelling compound is ready for tiling after 45 minutes. It can be used on plywood overlay and has sufficient flexibility to cope with the expansion and shrinkage caused by underfloor heating. For screeds with UFH, allow the screed to fully cool after commissioning. For electric underfloor heating systems, fully encase the wires in a layer of Tilemaster Rapid Level 30 and allow to dry.
Once the Rapid Level 30 has dried, Rapid Setaflex should be used to fix the tiles over the screed making sure the tiles are laid on a solid bed of adhesive with no voids. Rapid Setaflex is ready for grouting after 3 hours with a 30 minute pot life and has genuine S1 flexibility making it ideal for use on timber substrates and with UFH systems.
After fixing, tiles should be grouted with Tilemaster Grout 3000, a flexible, fast-setting wall and floor grout which can be used for joints between 1mm and 20mm. It is available in a range of 18 colours allowing you to colour match to the tile, or to use a contrasting colour as desired.
Lastly, when fixing over underfloor heating, wait at least one week after tiling completion before turning the heating system back on, and do so gradually to commission the tile installation. Once complete, the heating can be used as normal.
