Surface Preparation

The substrate must be free of all dirt, oil grease and loosely adhering particles and dry. Concrete floors must be dry in accordance with A.S. 1884-1985 Appendix A 70% Relative humidity maximum or Industry Standard (NZ=75%RH). Honeycomb and spalled concrete is to be repaired and any protrusions must be removed. Non porous concrete should have the surface removed by mechanical means such as diamond grinding.

Timber floors should have all coatings removed back to solid wood. It should be free from dust and any contaminant that may hinder adhesion. T&G flooring should be well fixed and demonstrating minimal movement. If required, Tile and Slate underlayment should be installed as per the manufacturer’s instructions to isolate the excessively moving T&G flooring prior to AKU-Tile® 4 being installed. Particleboard flooring should be dry, solid and firmly fixed in place.
