Large Format Tiles and Panels
4 With the increasing popularity of large format tiles, it is important to make sure the background is flat,
Straight
Allows air to escape and good compression of tile
plumb and true before tiling begins. It is also worth bearing in mind that the manufacturing tolerances for the tile are based on a proportion of the size of the tile. Please ensure that the back of the tiles are free of dust or contamination prior to adhesive application. When fixing large format tiles or panels, it is essential to use the correct adhesive (i.e. Class 2 plus F, T, E, S1 or S2 where applicable). Always consult the adhesive
✘ manufacturer and ensure as near as possible 100% coverage of tile adhesive.
Swirl
Traps air which can hinder compression
For large format tiles and panels, and tiles with ribbed or deep keyed back profiles, the tile adhesive should
be applied using the floating and buttering method,
i.e. a thin coat of adhesive buttered over the tile backs and should fill any deep keys before placing the tiles in position on the combed adhesive bed. Large format tiles may not be suitable for fixing in a brick bond pattern.
For further advice, consult TTA’s Technical ✘ Publication ‘Large Format Tiles in Internal Tiling’.
Dot and Dab
Creates weak points in tile
Thin Tiles
Advances in technology in the tile industry have allowed for the introduction of thin tiles, which can vary from 3mm to 5.5mm in thickness. It is important that you seek advice from the tile manufacturer and the tile adhesive manufacturer before fixing thin tiles.
