Protect your terrace from leaks and extreme summer heat with the elastomeric JSW iBlok WaterStop Roof Coat.
Why Choose JSW iBlok WaterStop Roof Coat?
Standard exterior paints fail on horizontal terraces because they cannot handle standing water or the extreme expansion and contraction of the roof slab. Here is why this specialized roof coat is the superior choice:
- High Elasticity (Crack Bridging): The advanced elastomeric property allows the dry film to stretch and contract significantly with severe temperature changes, effectively bridging static hairline cracks (up to 2mm) without tearing or snapping.
- Seamless Membrane Protection: It cures to create a monolithic, unbroken waterproof layer across the entire roof surface, completely eliminating the cold joints or seams where sheet-based leaks typically start.
- Heat Reduction (Cool Roof Technology): Formulated in brilliant white, the coating actively reflects harmful UV rays and solar heat. This acts as a thermal insulator, keeping the roof slab cooler and noticeably reducing the internal temperature of your top-floor rooms.
- Superior Water Resistance: Provides a robust, impermeable barrier that resists standing water (ponding) far better than standard exterior emulsions, preventing seepage into your ceilings.
Heat Reflective & Crack Bridging Guarantee
When you coat your terrace with the jsw iblok waterstop roof coat system, you are securing a professional-grade weather shield for your property.
Guaranteed to bridge structural hairline cracks up to 2mm and drastically reduce surface temperatures through high solar reflectance. Its thick, elastomeric acrylic film ensures long-lasting defense against standing water, algae growth, and heavy monsoon rains, keeping your interiors safe from ceiling dampness.
Durable and Flexible Terrace Waterproofing
The JSW iBlok WaterStop Roof Coat is an indispensable protective layer for flat concrete roofs, parapet walls, and sloped terraces.

How to Apply JSW iBlok WaterStop Roof Coat Correctly
Proper preparation is the most critical step to successful roof waterproofing. Follow these strict professional guidelines:
- Surface Preparation (Crucial): Thoroughly clean the entire roof surface. Vigorously wire-brush and power-wash to remove all loose material, old flaky paint, moss, algae, and grease. Repair deep structural cracks (wider than 2mm) with a polymer-modified cement mortar mix or dedicated crack filler. The surface must be completely dry before starting.
- Priming Coat: Create a self-priming coat by diluting the JSW iBlok WaterStop Roof Coat with 25-30% clean municipal water. Apply this thin, penetrative coat evenly across the slab with a roller or brush. Allow it to dry for 6-8 hours.
- First Waterproofing Coat (Undiluted): Apply the first full coat of the coating undiluted (straight from the bucket). Roll it out evenly, ensuring you extend the coating up the vertical parapet walls (at least 6 inches) to prevent sideways water seepage.
- Second Waterproofing Coat (Undiluted): After 6-8 hours, apply the second undiluted coat perpendicular to the first coat (in a cross-hatch pattern). This woven application technique ensures absolutely zero pinholes. A minimum of two full coats is mandatory for the warranty.
- Curing & Testing: Allow the completed elastomeric membrane to fully cure for 7 days before testing it with standing water (ponding test). Find detailed expert guidance on applying elastomeric cool roof coatings here.
Frequently Asked Questions (FAQ)
Q: Can I use this on vertical exterior walls?
A: Yes, absolutely. It provides excellent weather protection, crack-bridging, and significant heat reduction when applied to vertical exterior walls, especially those facing direct, harsh sunlight (like South or West-facing walls).
Q: Do I need to remove old terrace tiles before applying this coating?
A: For a guaranteed, permanent waterproofing solution, it is highly recommended to remove old, broken tiles and failing waterproofing layers to treat the base concrete slab directly. If the existing tiles are perfectly sound but leaking from the joints, you must consult the technical data sheet regarding the use of a specialized non-porous adhesion promoter (tile primer) before applying this coat.
Q: Can I use this over Asian Paints Damp Proof?
A: This product is designed to be used as a standalone waterproofing membrane system. While acrylic coatings are generally compatible, mixing brands (like applying JSW Roof Coat over Asian Paints Damp Proof) will void the manufacturer warranties of both products.
