Surfaces with an existing coating must be assessed for suitability before overcoating. If the surface shows any signs of delamination or contamination, it must be removed by grinding. If the surface is found to be be in sound condition, ensure it is clean and free of grease and oil. Stiff broom and general purpose cleaner recommended. Any oil stains should be treated & cleaned with an industrial degreaser. Pressure clean at minimum 2000 psi to clean and remove all contaminants. Once dry, surface must be abraded using 60-80 grit sand paper to ensure physical key. Vacuum surface & mop with damp cloth to remove all dust before overcoating. Removal of previous coatings by grinding is always preferred. Overcoating of previous surfaces is undertaken at applicators own risk. Note: If grinding is required, surface must be assessed once grinding has been completed to ensure the concrete has not become powdery or dusty, as this can cause delamination. If surface has become powdery, a hardener densifier may be required. 

Ensure concrete is sufficiently cured (recommended minimum 14 days). Concrete is to be clean and free of grease, oil, paint or any curing agent. Stiff broom and general purpose cleaner recommended. Any oil stains should be treated & cleaned with an industrial degreaser. Pressure clean surface at minimum 2000 psi and allow to dry. Acid etch with hydrochloric acid. Dilute approximately 20 parts water to 1 part acid (depending on porosity) to remove any loosely bound cement and laitance. Note: smooth concrete will require a higher acid content. Maximum strength - 10 parts water to 1 part acid. Apply diluted acid to surface using a large head watering can, applying in a criss cross motion (approximately 5-10m² sections). Acid will start to fizz on the surface once it starts to react with the laitance in the concrete. Pressure clean immediately to clean and remove all remnants of acid (do not allow acid to dry on surface). Pressure clean at minimum 2000 psi. If surface is uneven or in poor condition, grinding may be required. 

If applying by roller, it is recommended to use multiple trays to ensure product isn't sitting in mixed can. Large quantities of mixed epoxy will result in an exothermic reaction that will shorten pot life considerably
