Rust-Oleum CombiColor Orginal is the ultimate one coat system for metal protection.

Rust-Oleum CombiColor Metal coating is a primer and topcoat in one, based on a urethane modified alkyd, providing good drying properties at low temperatures. The product contains rust-inhibitive pigments and is lead and chromate free.

Ideal for interior and exterior use on bare metal, manually de-rusted metal or previously painted surfaces. Rust-Oleum CombiColor has excellent coverage and sag resistance, leaving no brush or roller strokes, and provides good drying properties even at low temperatures. Rust-Oleum CombiColor is a one coat maintenance system for metal, providing superior metal protection, even when applied direct to rust. It remains flexible and does not become brittle or flake with movement. Rust-Oleum CombiColor is intended for brush and roller application and can also be applied by air spray.

Over 400 RAL, BS & NCS colours are available to order, please call us for information.

Remove rust scale, loose mill scale, loose rust and loose coatings by scraping and wire brushing to St 3 (ISO 8501-1 : 1988), light blast cleaning or sanding. Sand intact coatings to roughen the surface slightly. The surface must be clean and dry during application. Galvanised, Zinc and Aluminium surfaces have to be primed first with CombiPrimer Tack Coat 3302.


Mix thoroughly using a wide bladed stirrer.


Temperature of air, substrate and coating material between 5° and 35°C and relative humidity below 85%. The substrate temperature must be at least 3°C above dew point.
