Application Instructions
Surface Preparation
Ensure substrate is clean, dust and stain free prior to application. Clean surface to remove any dirt, laitance, previous coatings or curing agents that may prevent penetration of the material.
The surface must be dry prior to application.
Confirm absorbency of surface with a light water spray, ensuring penetration into the surface is achieved.
It is recommended to undertake a test sample to confirm the suitability of the product for specific substrates and ensure desired results are achieved.
Application Method
Slowly stir the material until thoroughly mixed; Using a low-pressure sprayer fitted with an adjustable spray tip, surface must be flooded at a sufficient rate ensuring to achieve full saturation.
Substrates of greater porosity will benefit from a second application, wet on wet, to ensure penetration is achieved. The properties of the substrate such as porosity and profile will greatly influence the amount of material required.
