SUBSTRATE PREPARATION 1. All substrates must be structurally sound, dry, solid and stable. Any laitance, dust, grease, oil, paint or curing compounds present on the surface of the concrete substrate that may inhibit bond, shall be mechanically removed. The substrate should then be cleaned and prepared in accordance with the relevant standards and as per the MAPEI technical data sheets (TDS). 2. Substrates such as plasterboard, fibre cement boards, and plywood are generally not suitable in external environments. Some proprietary sheets may be suitable, but it is imperative that advice from the manufacturer is sought. There may be limits such as the height of installation, weight of tiling, degree of exposure to weather, and the need for mechanical fixing. 3. It is advisable to use mechanical fixings, such as metal angles or pin fixings, where the tile/stone is to be applied at a wall height exceeding 3 m above the ground with a stone/tile mass greater than 32 kg/m2 or a size of 600 x 600 mm or larger.
