Product TypeAdhesive
Product DetailNorcros Thick Bed Stone & Porcelain Grey Floor Tile Adhesive is a grey cement based thick bed floor adhesive designed for fixing fully vitrified porcelain, ceramic and natural stone tiles to a variety of floor surfaces. Its shrinkage compensating deep bed formulation makes it ideal for the installation of large format tiles and slabs affording excellent area contact without the need to back butter. It is water and weather resistant and is suitable for both internal and external locations. Containing unique Rock-Tite™ polymeric binders, the enhanced flexibility of the adhesive allows a greater range of fixing possibilities normally only achieved by the addition of separate admixtures. The adhesive has excellent thermal ageing properties and is particularly suitable for heated floors and timber floors when overlaid with WBP/Marine grade plywood.

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 to 4 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. Mix only enough material that can be used within the pot life of the product which will be around 30 minutes - this will be extended in cold conditions and reduced in hot weather/ warm temperatures.
Cleaning ToolsWash all tools frequently to avoid material bonding to them
Cleaning During ApplicationAlways keep a clean sponge and water available for wiping off any excess or spillages from paving
