How to Apply Indigo ST Red Oxide Metal Primer (Gold)

Proper metal preparation is critical for anti-rust performance:

1. Surface Prep (CRITICAL): The metal must be free of all rust, scale, grease, and loose paint. Use a wire brush or coarse sandpaper (80–120 grit) or sandblast if necessary. Wipe down with MTO Thinner to degrease. Find expert tips on preparing metal surfaces here.
2. Mixing: Stir the primer well. Dilute with MTO Thinner (10–25%) as required by the application method.
3. Application: Apply one coat using a brush or spray gun. Ensure joints and edges are coated generously.
4. Drying: Allow 8 hours for drying.
5. Finishing: If imperfections remain, apply Knifing Paste Filler, sand smooth, and re-prime the repaired area. Apply 2 coats of your chosen enamel topcoat.

Frequently Asked Questions (FAQ)

Q: Can I use this primer on galvanized (shiny) metal?
A: No, Red Oxide primers typically struggle with highly smooth, galvanized surfaces. For galvanized metal, a specialized zinc or universal primer is recommended.

Q: Can I use a water-based topcoat over this?
A: No, this is a solvent-based primer. It must be followed by solvent-based synthetic enamels or oil-based topcoats.

Q: Does this replace the need for sanding?
A: No, proper sanding to remove existing rust is the single most important step for the primer to work effectively.
