Tilemaster Rapid Setaflex – Rapid Setting Floor & Wall Tile Adhesive
Tilemaster Rapid Setaflex – Rapid Setting Floor & Wall Tile Adhesive is a polymer modified, flexible rapid setting cement based floor and wall tile adhesive with increased adhesion and non-slip properties. Tilemaster Rapid Setaflex has been specially formulated for fixing a large variety of tiles including ceramic, porcelain and natural stone tiles to substrates subject to limited movement and/or vibration such as plywood overlay and underfloor heating systems as well as for fixing to solid substrates such as concrete and sand/cement screed. Its rapid setting capability allows for light foot traffic and grouting after 3 hours. Tilemaster Rapid Setaflex is ideal for areas subject to prolonged or permanent wet conditions such as swimming pools. Tilemaster Rapid Setaflex can be used internally and externally and it is unaffected by frost after setting.
Preparation of the substrate:
Before starting, all substrates must be clean, dry and strong enough to support the weight of the tiles, tile adhesive and grout. Remove all dust, dirt, oil, grease and other contaminants that may affect adhesion.
Mixing and Application of the product:
Only mix small quantities at a time until you have become accustomed to the fast setting nature of the product. Always mix powder to water and mix to a smooth and lump free consistency. As a guide for powder to water ratio, 20kg of powder requires approximately 4.4 – 4.6 litres of water. Never add water after initial mixing, as this will impair the strength of the adhesive. Product that has started to set must be discarded.
NB. When fixing large format tiles, natural stone tiles and tiles that have deep studs on the back, you must skim the back of the tile with a thin 1 –
2mm layer of adhesive, this is referred to as back buttering. This will significantly improve the bond strength.
On a flat, even substrate where dry conditions exist, apply adhesive to the substrate as a thin floated coat at a uniform thickness of 3mm – 6mm and then rib / comb out using a suitable notched trowel. Where substrate conditions do not allow thin bed fixing, Tilemaster Rapid Setaflex can be applied to a maximum bed thickness of 12mm. Ensuring the adhesive is still moist, bed tiles into adhesive using a twisting action ensuring full coverage of adhesive between tile and substrate. Regular checks should be made to make sure that there are no voids in the adhesive bed.
