Indigo ST Universal Primer: The Multi-Surface Solution for Metal, Wood, and Walls
Simplify your painting preparation with Indigo ST Universal Primer. This advanced single-pack, multi-surface primer is engineered to bond effectively with a wide variety of substrates, eliminating the need to stock separate primers for metal, wood, and masonry. Whether you are painting a metal gate, varnishing a wooden cabinet, or priming a plaster wall, Indigo ST Universal Primer delivers superior adhesion and creates a perfect, non-porous foundation for your topcoat.
Its powerful formulation saves time by acting as a single, durable base coat suitable for most household painting needs, providing excellent resistance to corrosion on metal and sealing on porous wood.
Why Choose Indigo ST Universal Primer?
The flexibility and adhesion of this universal primer make it a professional favorite:
- True Multi-Surface Adhesion: Bonds securely to iron, steel, aluminum, bare wood, plywood, MDF, and interior/exterior cement plaster.
- Corrosion Resistance: Contains active pigments that provide anti-rust protection on ferrous metal surfaces, though it is not a heavy-duty Zinc Chromate replacement.
- Excellent Sealing: Seals the pores of porous materials like wood and masonry, preventing the topcoat from sinking in unevenly.
- Universal Topcoat Compatibility: Serves as an ideal base for both alkyd-based enamels (oil paints) and water-based emulsion topcoats.

How to Apply Indigo ST Universal Primer
Proper surface preparation ensures optimal multi-surface adhesion:
- Surface Prep (CRITICAL): The surface must be dry and free of oil, grease, and loose particles. For metal, remove rust using a wire brush or sandpaper (80–120 grit) and wipe with thinner. For wood, sand lightly.
- Mixing: Stir the primer well. Dilute with MTO Thinner (10–25%) as required by the application method.
- Application: Apply one coat using a brush or spray gun. Ensure the film thickness is uniform.
- Drying: Allow 8 hours for drying.
- Finishing: If imperfections exist, apply Knifing Paste Filler (for small dents/scratches), sand, and then proceed with 2 coats of your chosen topcoat enamel or interior emulsion. Find expert tips on multi-surface priming here.
Frequently Asked Questions (FAQ)
Q: Can I use this primer on all exterior surfaces?
A: Yes, it is suitable for exterior metal, wood, and masonry, provided the surface is properly prepared and a durable exterior topcoat is applied.
Q: Does this replace my specialty primers?
A: For heavy-duty industrial metalwork or highly alkaline new plaster, a dedicated primer (like Zinc Chromate or specialized masonry primer) is recommended. This is best for general-purpose home maintenance.
Q: Is this water-based?
A: No, the Indigo ST Universal Primer is solvent-based (thinnable with MTO) for enhanced adhesion to difficult surfaces like metal and glossy wood.
