Indigo Sealer Primer – Platinum Series (Water Based Sealer)

Indigo Sealer Primer (Platinum): The Ultimate Multi-Surface Sealing Foundation

For demanding surfaces that require a tough, multi-functional base coat, Indigo Sealer Primer (Platinum) delivers the highest level of performance. This premium single-pack, solvent-based sealer primer is formulated with advanced resins to penetrate, stabilize, and seal surfaces, making it an ideal foundational coat for both challenging interior and exterior environments.

The **Indigo Sealer Primer (Platinum)** acts as a superior binding agent, effectively consolidating old, porous, or chalky substrates. Its sealing power prevents paint from sinking unevenly into the plaster and provides exceptional resistance to efflorescence and alkali attack, ensuring your final premium emulsions or exterior paints look flawless and last longer.

Why Choose Indigo Sealer Primer (Platinum)?

The Platinum Series designation signifies maximum protection and durability:

• Extreme Sealing Power: It stabilizes highly porous or chalky surfaces (like aged plaster or exposed brick), bonding loose particles together for a solid base.
• Alkali and Efflorescence Blocking: Creates an impenetrable barrier that stops salts and chemicals from migrating to the surface, protecting expensive topcoats from damage.
• Multi-Surface Compatibility: Highly versatile, offering excellent adhesion on interior walls, exterior masonry, and even specific wooden or metal surfaces (when properly prepared).
• Prevents “Flashing”: Ensures uniform absorption, leading to a consistent sheen and colour across the entire finished wall.

Key Features of Indigo Sealer Primer (Platinum)

• Type: High-Performance Solvent-Based Resin Sealer.
• Usage: Interior and Exterior Cement, Masonry, and Plaster (Ideal for problematic surfaces).
• Finish: Transparent Matt.
• Thinner: Mineral Turpentine Oil (MTO) or General Purpose Thinner.

Recommended Application Areas

This premium sealer primer is indispensable for:

• Chalky & Powdery Walls: Consolidating weak, old plaster both indoors and outdoors.
• New Construction: Blocking high alkalinity from freshly cured cement before putty application.
• Waterproofing Systems: Providing the essential first coat before applying flexible coatings or waterproofing membranes.
• Transition Areas: Ideal when moving from plaster to cornice or other dissimilar porous materials.

How to Apply Indigo Sealer Primer (Platinum)

Due to the solvent content, proper ventilation and safety are paramount:

1. Surface Prep: Ensure the wall is clean, dry, and free of all loose paint, dust, and grease. Use a wire brush or sandpaper to remove chalkiness.
2. Mixing: Dilute Indigo Sealer Primer (Platinum) with 5-15% MTO Thinner. Stir well. Minimal dilution is recommended for maximum penetration on very chalky walls.
3. Application: Apply one liberal coat using a brush or roller. Ensure the entire surface is saturated so the primer penetrates deeply.
4. Drying & Next Step: Allow 8–10 hours to dry completely. Do not proceed until the primer is fully cured. You can then apply wall putty (if needed) or the final emulsion coat.

Frequently Asked Questions (FAQ)

Q: Can I apply water-based putty over this solvent-based primer?
A: It is generally best practice to avoid applying water-based putty over solvent-based primers, as it can compromise adhesion. If leveling is needed, wait until the primer is fully cured (24 hours) or use a solvent-compatible product.

Q: Is this primer essential for new walls?
A: While a standard water-based primer is sufficient for non-problematic new plaster, this sealer is essential if the plaster is highly porous or if you need absolute confidence that the wall’s alkalinity is blocked before using a high-end luxury paint.
