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.
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 Slip Resistant Chemi-Coat 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 wide bladed tool until an even colour is obtained. Do not mix the aggregate into the epoxy resin.
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. The mixed components have a pot life of one hour at 15°C, which reduces at higher ambient temperatures. To extend pot life in higher temperatures the mixed components should be decanted into a shallow tray.
Application
Best results are obtained in warm conditions, (minimum 15°C). Apply by medium, pile type roller (not foam) in one coat. Whilst the coating is still wet, sprinkle the grit sparingly over the surface at a rate of 1 pack of grit per 18m². For maximum chemical resistance, apply a coat of Chemi-Coat as a sealer and allow to cure overnight before applying the anti-slip coat.
