Will Rubba-Roof Professional adhere to metal surfaces?
For ferrous metal substrates, remove any previously applied coatings, rust and scale by mechanical means, or wire brush if rust is only superficial. Apply Rubba-Roof Pro primer to dusty surfaces. Prepare the surface immediately prior to coating to prevent flash rusting. Apply one or two coats of Rubba-Roof Pro. Do not apply to deeply rusted surfaces without first treating with anti-corrosive primer. Non-ferrous surfaces such as lead, copper, brass, stainless steel and sound galvanizing should be cleaned and thoroughly degreased before application of Rubba-Rood Pro™. Damaged/rusted galvanised sheet should be treated as for ferrous substrates.
