Indigo Aqua Shield (Protect Plus) – Waterproofing

Indigo Aqua Shield: The Ultimate Waterproofing Exterior Primer

For exterior walls facing rain, humidity, and the damaging effects of alkali, Indigo Aqua Shield (Protect Plus) is a specialized, high-performance base coat designed to protect your walls from dampness, efflorescence, and peeling paint. This is an advanced, flexible acrylic-cementitious waterproofing barrier that seals the wall surface completely before any decorative paint is applied.

Positioned within the Indigo ‘Protect Plus’ range, Indigo Aqua Shield (Protect Plus) offers superior crack-bridging and excellent resistance to alkalinity. It is essential for areas subject to intermittent moisture or condensation, ensuring a solid, dry foundation that prevents fungal growth and maintains the aesthetic integrity of your final emulsion paint layer. Its primary function is to serve as a durable, alkali resistant primer base.

Why Choose Indigo Aqua Shield (Protect Plus)?

Indigo Aqua Shield (Protect Plus) is a specialized barrier, not just a paint, offering critical protection:

• High Flexibility: The coating remains flexible, allowing it to bridge hairline cracks (up to 0.5mm), preventing future water entry points.
• Anti-Alkalinity Barrier: It seals the wall against efflorescence (white salt patches) and alkalinity, which can degrade standard primers and paints. This is crucial for new plaster.
• Superior Adhesion: Provides an aggressive bond to concrete and plaster, acting as an impermeable base for wall putty and exterior topcoats.
• Fungal Protection: Creates an environment where fungi, mold, and mildew cannot grow, ensuring a hygienic surface, making it superior to standard exterior primers.

How to Apply Indigo Aqua Shield (Protect Plus)

This is a 2-step application system for maximum effectiveness:

1. Surface Preparation: Remove all loose paint, putty, and plaster. The surface must be clean and free of efflorescence. Pre-wet the surface with water before application.
2. Mixing: Mix the powder component with the liquid polymer component in the ratio specified on the packaging. Use a mechanical stirrer to ensure a smooth, lump-free paste.
3. First Coat: Apply the first coat using a brush or roller, working the material into the pores and cracks. Allow to dry for 6-8 hours.
4. Second Coat: Apply the second coat perpendicularly to the first coat (to ensure full coverage) and allow it to dry fully.
5. Finishing: The surface is now waterproofed. Apply wall putty (if needed), followed by a regular Primer coat, and finally, your decorative topcoat. Learn more about proper surface preparation techniques.
