• Anhydrite and Hemihydrite (Gypsum) screeds: These must be cured to the respective manufacturer's recommendations before tiling commences. Surfaces to be free of laitance and sealed with two coats of Norcros Prime Bond.
• Asphalt (internal only): Flooring grade asphalt can be tiled directly.
• Cement: Sand render: Must be at least 14 days old.
• Concrete and screeds: New concrete must be allowed to dry for a minimum of six weeks, residual traces of laitance and curing agents should be mechanically removed before tiling commences. Screeds should be a minimum 21 days old.
• Glazed surfaces: These must be well fixed and able to support additional tile weight. Old glazed surfaces must be thoroughly degreased. The addition of Norcros Adiflex will be required. Alternatively, a slurry bonding coat of one-part Prime Bond to two-parts Mosaic and Marble Fix can be brushed onto the surface and allowed to dry, providing a key for the adhesive.
• Gypsum plaster board: Seal with Norcros Prime Bond.
• Gypsum plaster: Seal with Norcros Prime Bond. In wet areas, moisture sensitive backgrounds should be sealed with Norcros Wet Seal.
• Heated floors (dense construction): The addition of Norcros Adiflex in the adhesive is necessary with under-floor and under-tile heating systems. Heating must not be switched on for a minimum 14 days after tiling. Norcros Universal Leveller can be used to provide protection to heating pipes.
• Plywood overlay (WBP): Tiling over plywood is achieved with the addition of Norcros Adiflex, sheets must be sealed on the back face and edges with Prime Bond.
• Thermoplastic Floor Tiles/ Vinyl sheet: If the existing flooring is in good condition, degrease and seal with neat Norcros Prime Bond.
