Rust-Oleum 769/780 Damp-Proof Rust Primer - Corrosive Protection Primer
Rust-Oleum 769 Damp-Proof Rust Primer is a single pack primer based on a fish oil containing alkyd. This unique formulation allows direct application on slightly moist or dry metal surfaces, making it ideal for rusted steel surfaces. The primer penetrates rust to expel moisture and air, encapsulating rust for superior protection.
Application & Surface Preparation
Before applying the primer, ensure surfaces are free from grease, oil, and other contaminants using a cleaner or high-pressure steam. Remove loose rust and coatings by scraping, wire brushing, or light sanding. The primer can be applied with a brush, roller, or spray, with recommended thinning using Rust-Oleum Thinner 633 for brush and roller, and Thinner 641 for spray applications.
- Brush: Dilute up to 10% with Thinner 633.
- Roller: Dilute up to 10% with Thinner 633, using medium pile rollers.
- Airless Spray: Dilute up to 5% with Thinner 641, using a tip size of 0.013-0.015 inches.
- Air-atomised Spray: Dilute 10-20% with Thinner 641, using a tip size of 1.2-1.8 mm and 2-4 bar pressure.
The primer is touch dry within 4 hours and can be recoated after 24 hours. Ensure all tools are cleaned with Rust-Oleum Thinner 160 or mineral spirits after use.
Why Choose Rust-Oleum 769?
