Indigo Exterior Wall Primer – Gold Series (Solvent Based)

Indigo Exterior Wall Primer (Gold, Solvent Based): Heavy-Duty Sealing and Protection

For walls requiring maximum penetration and sealing, Indigo Exterior Wall Primer (Gold, Solvent Based) is the professional-grade solution. This primer is engineered with specialized resins to penetrate deep into porous or chalky exterior masonry, binding the surface particles together to create an exceptionally strong and stable base. It is the crucial first step for long-lasting exterior paint systems.

The **Indigo Exterior Wall Primer (Gold, Solvent Based)** is particularly effective on old, weathered surfaces where a water-based primer might simply sit on the surface. Its solvent carrier ensures the primer liquid is absorbed deep into the plaster, locking it down and preventing premature paint failure. This is why professionals choose the gold standard for challenging exterior projects.

Why Choose Indigo Exterior Wall Primer (Gold, Solvent Based)?

The Solvent-Based Gold Series offers unmatched bonding power for difficult surfaces:

• Superior Penetration: The solvent medium allows the resin to penetrate far deeper into dusty, chalky, or porous plaster, achieving a stronger bond than any water-based primer.
• Alkali Blocking: Creates a heavy-duty chemical barrier against the efflorescence and alkalinity present in masonry, protecting the final paint colour and sheen.
• Excellent Sealing: It completely seals the wall, stopping water and moisture ingress from the outside and preventing paint from sinking unevenly into the substrate.
• Strong Adhesion: Provides the perfect, chemically locked-down surface for high-end exterior emulsions and coatings.

Key Features of Indigo Exterior Wall Primer (Gold, Solvent Based)

• Type: Single-Pack Alkyd/Oil-Based Resin.
• Usage: Exterior Cement and Masonry Surfaces (especially old/chalky walls).
• Finish: Matt.
• Thinner: Mineral Turpentine Oil (MTO) or General Purpose Thinner.

Recommended Application Areas

This premium solvent primer is highly recommended for:

• Chalky Walls: Binding and consolidating old, chalky exterior paint or plaster surfaces.
• Porous Plaster: Heavily porous cement that absorbs paint quickly.
• Exterior Facades: As a robust base coat for high-durability waterproofing and premium exterior emulsions.
• Problem Walls: Any exterior wall where a standard water-based primer has failed to bind properly.

How to Apply Indigo Exterior Wall Primer (Gold, Solvent Based)

Due to the solvent content, proper ventilation and technique are crucial:

1. Surface Prep: Clean the surface thoroughly. Remove all loose paint and repair cracks. Ensure the wall is completely dry—do not apply over wet plaster.
2. Sanding/Wire Brush: Use a wire brush or 180-grit sandpaper to remove all chalk and dust. Wipe clean before priming.
3. Mixing: Dilute Indigo Exterior Wall Primer (Gold, Solvent Based) with 5-15% MTO Thinner. Stir well.
4. Application: Apply one liberal coat using a brush or roller. Ensure the primer soaks well into the substrate.
5. Drying & Next Step: Allow 8–10 hours to dry completely. Do not apply water-based putty over solvent primer; if leveling is needed, use a solvent-based putty or apply the topcoat directly.

Frequently Asked Questions (FAQ)

Q: Can I apply water-based paint over this primer?
A: Yes, once the primer is fully dry (10-12 hours), you can apply water-based exterior emulsions. The primer provides the necessary stable interface.

Q: Why is the drying time so long compared to a water primer?
A: The solvent needs time to evaporate completely, which is essential for the resin to penetrate deeply and bind the surface effectively. This slower process is key to its superior durability.
