UltraTileFix ProRapid RS is a single-part, rapid setting, flexible adhesive for wall and floor tiles. It is specially formulated with enhanced adhesion and flexibility for use with ceramic, porcelain and natural stone tiles. UltraTileFix ProRapid RS is a polymer-modified adhesive suitable for use with the most common substrates. It is able to take light foot traffic within 3 hours of installation depending upon temperature and substrate.
All wall and floor substrates must be clean, dry, firm and stable, free of dust, dirt, oil and grease. Substrates should be strong enough to support the weight of the adhesive and tiles being fixed (see below for loadings). For plasterboard and plaster finishes that have been painted and are showing a weak or flaky surface finish then mechanical sanders or hand sanding blocks are generally used to remove the film. However, for the likes of floor screed surface contamination, adhesive residues and weak surface laitance or even smooth dense floors such as power floated concrete, these will require a more heavy-duty scarifying using specialist flooring equipment to remove the surface of the substrate to ensure the substrate is sound, stable and has a rough open texture. To encourage best adhesion to the substrate it is advisable that prior to applying adhesive that substrates are primed (please see priming section below). Remember - sanding or mechanical abrasion of any surface will leave powder deposits which require thorough removal by suitable vacuum equipment to provide a clean dust-free surface. Failing to remove fine powder deposits and weak surfaces is a common reason for the de-bonding of tile adhesive and primer from the substrate. Using a wet sponge to clean down a wall or floor of dust deposits only serves to spread it around, it is, therefore, advisable to vacuum thoroughly prior to use of wet sponge.
