Concrete Ensure surface is clean and free of all loose material. Watco Tack Coat may be applied over existing paint but all poorly bonded paint must be removed and well bonded paint roughened to provide a key. Check that there is no ice in the substrate.
Metal Remove any loose or flaking material and rust by wire brushing or disc grinding. Oil or grease should be removed with Watco Bio D and the metal allowed to dry. Watco Tack Coat should be applied immediately after cleaning and drying.
Pour the contents of the smaller tin into the larger tin and mix thoroughly with a wide bladed tool. When using the 6m² pack decant into a shallow tray. Do not leave mixed components in the tin - the product will quickly become unusable and the tin become hot. Use immediately, the pot life of the mixed components is 20 minutes maximum at 20ºC, less at higher temperatures.
Apply sparingly by roller or brush and allow to become ‘tacky’. Overlaying must be completed while the Watco Tack Coat is still tacky. This product should be applied above 10ºC to ensure proper curing.
