JSW iBlok WaterStop Damploc – Interior (Anti-Damp Undercoat)

JSW iBlok WaterStop Damploc Interior: Heavy-Duty Anti-Dampness Basecoat

JSW iBlok WaterStop Damploc Interior is a revolutionary, specialized primer and waterproofing coating designed to permanently solve interior dampness problems. Unlike regular primers that only provide superficial adhesion, this product forms an impermeable, flexible barrier that blocks water ingress and high pH levels (alkali) migrating through the interior walls.

Ideal for walls suffering from efflorescence (salt patches) or moisture due to external seepage, JSW iBlok WaterStop Damploc Interior seals the surface and provides a dry, stable base. This interior waterproofing primer ensures that your final topcoat of emulsion paint adheres flawlessly and remains free from damp patches, blisters, and peeling for years.

Why Choose JSW iBlok WaterStop Damploc Interior?

Dampness is often a sign of water pushing from the outside. This product is engineered to resist that pressure:

• Permanent Dampness Solution: Forms a dense, tough membrane that resists hydrostatic pressure, stopping water migration from behind the wall.
• Anti-Efflorescence: Effectively blocks the release of soluble salts from the plaster, which cause those unsightly white, flaky patches.
• Alkali Resistance: Highly resistant to high pH levels in new concrete or old plaster, protecting the topcoat color and finish.
• Breathable System: While blocking water, it allows water vapor to escape from the wall, reducing the risk of blistering and long-term damage.

Key Features of JSW iBlok WaterStop Damploc Interior

• High Film Thickness: Built to provide a substantial, dense layer for maximum protection in problem areas.
• Strong Adhesion: Bonds aggressively to concrete, plaster, brickwork, and masonry.
• Excellent Coverage: Despite its thickness, it spreads well for an anti-dampness coating.
• Ready-to-Use Formulation: Comes pre-mixed (though may require slight thinning with water) for consistent quality and easy application.

Recommended Application Areas

This specialized primer is crucial for:

• Ground Floor Walls: Where rising damp and capillary action are common issues.
• Bathrooms/Kitchen Walls: Interior walls that back onto wet areas or exterior leakage zones.
• Any Damp Spot: Localized application on walls showing signs of efflorescence or blistering paint.
• New Plaster: As a protective basecoat against residual cement alkalinity.

How to Apply JSW iBlok WaterStop Damploc Interior

Proper preparation is key to stopping dampness permanently:

1. Surface Preparation: Scrape off all existing loose paint, plaster, or efflorescence salts. Sand the wall with 180-grit sandpaper to achieve a clean, sound surface.
2. Cleaning: Wash the wall thoroughly. For heavy salt deposits, wipe down with a mild solution of vinegar or citric acid and rinse well. The wall must be allowed to dry completely before application.
3. Application: Apply the first coat of JSW iBlok WaterStop Damploc Interior using a brush or roller. Ensure a thick, uniform coating.
4. Recoating: Allow 6-8 hours for the first coat to dry. Apply a second coat to ensure complete sealing and maximum barrier formation.
5. Finish: After the second coat is fully dry, you may proceed with wall putty (if required for leveling) and then your chosen interior emulsion topcoat. Find expert advice on fixing persistent dampness issues.

Frequently Asked Questions (FAQ)

Q: Can this be used on the exterior side of the wall?
A: While highly effective, specialized exterior waterproofing products are recommended for surfaces exposed directly to rain.

Q: Can I use putty directly over Damploc?
A: Yes, you can use high-quality acrylic or cement-based putty directly over the dried Damploc coat. Ensure the Damploc has cured for 24 hours before applying putty.

Q: Does this product need thinning?
A: It is generally used as supplied, but if the consistency is too thick for application, you may dilute it sparingly (max 5%) with clean water.
