Surface Preparation: Concrete and BrickConcrete to be treated must be dry, at least four weeks old and free of any soft surface laitance, contaminants, and not subject to rising damp. All loose material should be removed. Very smooth bare concrete or concrete with soft surface laitance should be etched with
Watco Cemtetch and the area thoroughly hosed off and allowed to dry. Grease or oil should be removed with
Watco Bio D (or similar degreasant) and the area thoroughly hosed off and allowed to dry. Very smooth previously painted surfaces should preferably be abraded to improve adhesion.
Surface Preparation: SteelRemove loose or flaking material, rust and any previous coatings by wire brushing or disc grinding to achieve a bright surface. Oil or grease should be removed with Watco Bio D and the metal then washed with water and allowed to dry. Coating should be carried out immediately providing flash rusting has not occurred.
Mixing
Each pack consists of a container of curing agent and a container of resin. The curing agent and resin must be very thoroughly mixed together with a
Watco Paint Mixer or a wide bladed tool until an even colour is obtained.
Important Once the contents of the pack have been mixed a chemical reaction takes place which causes a rise in temperature and speeds up the curing of the product.
Application
Best results are obtained in warm conditions, (minimum 15°C). On horizontal surfaces apply by medium, pile type roller (not foam) in one coat. On vertical surfaces two thin coats are recommended. The second coat should be applied within 24 hours.
