Product DetailNorcros One Part Flexible Grey is a highly polymer fortified adhesive mortar for use on walls & floors in both internal and external locations. It requires only the addition of water as it is specially formulated with Rock-Tite™ polymeric binders to impart flexibility, water resistance and increased strength - usually only achieved by the addition of polymer admixtures.

Pointing PreparationAll surfaces should be dry, clean and strong enough to support the tiles to be fixed. Tiling substrates should be true and flat to permit fixing without visible lipping of tile edges. On floors, any gaps exceeding 3mm under a 2 metre straight edge should be corrected using a suitable Norcros Levelling Compound. This will be particularly appropriate where larger tiles or those with rectified edges are being installed. Porous or dusty surfaces must be sealed using Norcros Prime Bond diluted 1:4 with water.
MixingInto a clean pail add 1 part of cold water and gradually introduce approximately 3.5 parts of adhesive powder stirring to blend the mixed mortar to a smooth lump free consistency. The properly mixed mortar will be thick enough to hold the adhesive ribs without slumping. The product has an ease of use pot life of up to 4 hours, however this will be extended in cold conditions and reduced in hot weather/warm temperatures.
Application ProcessUsing a suitably notched trowel spread the adhesive onto the fixing surface to form parallel ribs into which the tiles should be applied with a firm twisting action. Spread only enough material that remains workable and as such fully wets out on the tile backing. Solid-bed void-free fixing will be necessary on floors and in wet areas. Tiles with deeply keyed back profiles may need to be back buttered. The adhesive is designed for thin bed fixing up to 6mm although in isolated areas it can be bedded out up to 12mm in thickness. Tiles may be grouted as soon as the adhesive bed is set. Do not use below 5°C. Refer to the product guide for further information.
