Heavy Red Oxide Primer (hematite oxide) | RO-350

Heavy Red Oxide Primer RO-350, Complete rust & anti-corrosion control with hematite oxide.

Our RO-350™ is formulated as a high performance, fast air-dry phenolic-modified alkyd resin primer. Developed to provide exceptional protection against rust on metal surfaces as a first step primer prior to top coating. RO-350 utilizes a pigment of heavy hematite oxide as a anti corrosive barrier to virtually block 99% of damaging ultra violet rays. No primer works better than our RO-350™ Heavy Red Oxide in holding back and reforming rust. RO-350™ is the first step in rust proofing any surface that has been compromised by rust.

Directions for use:

Prepare the rusted surface by first removing any loose rust with a wire brush, sanding, or blasting. Rinse surface with water and allow to dry before priming with RO-350. Apply RO-350 by hand with a rag, brush, roller, or sprayer. Allow to dry 15 minutes before application of topcoat. RO-350 is fully dry and cured after 24-48 hours.
