Application Guide
- Check conditions. Surface and air must be at least 7.2 °C, and not within 5 °F of the dew point. Deep colours, humidity and cool weather slow drying.
- Prep. Remove wax, oil, grease, dust, loose rust and peeling paint. Dull glossy surfaces. Dull new, shiny non-ferrous metal with fine sandpaper.
- Prime where needed. Steel and iron can be coated directly. Use a rust-inhibitive metal primer for extra protection, and an acrylic metal primer on galvanized steel and aluminum.
- Stir well with a lifting motion. Do not thin.
- Apply a full coat, keeping a wet edge to avoid lap marks.
- Recoat after 12 hours. Clean tools with mineral spirits.
FAQ
1How much Rust-A-Void do I need?
A 3.79 L can covers 350–450 sq ft per coat. A 4 ft × 30 ft metal fence painted both sides is about 240 sq ft, so a 3.79 L can is enough for one coat.
2Do I need a primer?
On steel and iron you can apply it directly, though a rust-inhibitive metal primer is recommended for extra protection. Galvanized steel and aluminum need an acrylic metal primer.
3Can I paint over rust?
Remove loose rust and peeling paint first. The data sheet requires a surface free of loose rust, wax, oil, grease and dust.
4Is it for interior or exterior?
Both. It is listed for interior and exterior metal. It is not for immersion service, and it is for metal only.
5Which finish should I choose?
Satin for a low-sheen look, Semi-Gloss for a middle sheen and Gloss for the shiniest finish. Satin and Semi-Gloss come in fewer colours than Gloss.
6How long before I can recoat?
Touch dry in 2 hours and recoat in 12 hours at 25 °C and 50% humidity. Dark colours, humidity and cool weather make it longer.
7What is the best season to paint outdoors in Canada?
Any dry day at 7.2 °C or warmer, with no rain expected and the metal well above the dew point. Late spring to early fall is the easiest window.
8How do I clean up and dispose of rags?
Clean tools with mineral spirits right after use. Benjamin Moore warns that soaked rags can ignite on their own, so put them in a sealed, water-filled metal container.
