Surface preparation
All surfaces should be clean, dry, and free from oil and grease. Old stone surfaces may be extremely hard and shiny. The performance of Watco Stepmarker in these situations will be improved if the surface can be scarified first. If nothing else is available, vigorous use of a wire brush will assist.
Concrete should be sound and free from laitance and dust. Timber should be hard, dry and free from oils. Abrasion is recommended. Not suitable for use on inherently oily timbers unless they are abraded thoroughly. Abrade steel to a bright surface before coating. Do not use a primer. Other metals should be clean and dry. Mask the area to be painted with masking tape.
Ensure any interiors are well ventilated before application.
Mixing
Add the entire contents of the curing agent (smaller tin) to the contents of the resin (larger tin) and mix thoroughly with a flat bladed tool until thoroughly blended and of a uniform consistency. Pay particular attention to the sides and bottom of the can. Pour into a paint kettle or tray before application. The mixed product has a working life of approx. 6 hours at 20°C.
Application
Do not apply at temperatures below 5°C. At surface temperatures below 10°C the coating may stiffen during application, but this will not affect performance. Apply by brush or roller to the prepared surface. Brush application usually reduces coverage but allows a thicker coating to be used. One good coat is usually sufficient.
