The large variety of tiles in many different types of materials now available has, inevitably, created a demand for their presence on the walls and floors in both domestic and commercial applications and the ability of a tiler to be fully competent to install wherever required.It is crucial that a professional tiler would have gained all-round training on approved tiling courses at an established training centre like AbleSkills with fully equipped teaching facilities, which provide accredited NVQ tiling course qualifications by an industry-recognised body such as City & Guilds.Following its application in numerous leisure facilities, office and workplace premises there has been a growing trend within the residential sector towards installing porcelain and vitrified tiles to walls, rather than the ceramic type. However, porcelain and vitrified tiles, unlike porous bodied tiles, shrink in the firing process and consequently, specified allowances have to be made to dimensional accuracy in the manufacturing process. As a result of the differing methods of manufacturing processes and materials, larger, thicker format tiles, complying with BS6431 are being produced.Current British & European Standards for ceramic tiles define tolerances for dimensions and for centre curvature of tiles, depending on tile type and size. The tolerances for tile fixing set down within British Standard BS5385 for tile fixing are demanding and, as a result of the differences in manufacturing and fixing tolerances, special consideration has to be given to fixing tiles, which are either fully vitrified or semi-vitrified, glazed or unglazed, to walls.It's important to be aware that any tile installation process requires meticulous preparation and assessment of an area to be tiled. Very often, both the underlying wall and floor structure will not be uniform, waterproof, or otherwise suitable for laying of particular types of tiles and will need to be brought up to regulatory standard. Similarly, wall and floor surfaces must be closely examined, and if necessary completely replaced, before tiling work can commence.Candidates enrolled on a professional tiling course obtain vital units of knowledge, practical skills and experience in order to be thoroughly versed in site preparation issues such as tanking / screed laying, sand / cement rendering, plaster and plasterboard weight restrictions, curing and drying, etc. Tiling students on particular tiling course units will also learn to deal with a variety of installation challenges presented by, for example?
