Rustex is normally used for treatment of rusted steel prior to application of paint or other coating systems.

It is ideal for situations where blast cleaning is not practical or desirable.

Remove all dirt, old paint and loose rust by wire brush, in accordance with St2 standard.
Wash with a water-based detergent solution to remove oil and dust, followed by thorough rinsing with clean water.
The surface may be damp BUT NOT WET when Rustex is applied.

Stir well before use.
Any rust particles picked up on the paintbrush will be liable to contaminate the paint in the container, reducing the shelf life.
This can be avoided by pouring a sufficient amount into a separate plastic container for each operation. DO NOT return unused material to the original container.

Brush application is recommended for the first coat to ensure thorough penetration into the rust.
Other application methods are:
Roller – a short nap roller may be used. Foam rollers are not recommended.
Air assisted spray – thin with up to 10% water. Use a 0.40mm, 40-60o tip and 40-80 psi air pressure.
Airless spray – typically a 28:1 airless spray unit at 70 psi would be used, with 0.25-0.40mm, 40-60o tip and 1400-2100 psi fluid pressure at tip.
