JSW iBlok Crack Fix (Flexible Paste): Permanent Repair for Wall Cracks
JSW iBlok Crack Fix is a specialized, ready-to-use, flexible acrylic paste designed for sealing and repairing surface cracks in plaster and masonry walls. Unlike brittle cement fillers that crack again when the wall moves, JSW iBlok Crack Fix forms an elastic seal that accommodates structural movement, providing a long-lasting, durable repair for internal and external hairline cracks.
This flexible crack filler is a vital step in surface preparation, ensuring that the cracks do not reappear under the finished coat of exterior emulsion. Its smooth consistency makes application easy and ensures the repaired area blends seamlessly with the surrounding wall.
Why Choose JSW iBlok Crack Fix?
Cracks are not just aesthetic issues; they are entry points for water. This product solves both problems:
- High Flexibility: Contains specialized acrylic polymers that allow the paste to stretch and move with the substrate, preventing the re-emergence of cracks.
- Ready-to-Use Paste: Saves time and effort as it requires no mixing. It has a non-sag consistency ideal for horizontal and vertical applications.
- Water Resistance: Once cured, it forms a waterproof barrier within the crack, protecting the underlying structure from water damage.
- Paint Compatibility: It adheres strongly to plaster and concrete and is fully compatible with JSW primers and water-based paints.
Key Features of JSW iBlok Crack Fix
- Crack Bridging: Ideal for cracks up to 5mm wide.
- Excellent Adhesion: Bonds aggressively to masonry surfaces without the need for additional binders.
- Fast Drying: Allows faster project completion than traditional cement-based crack repair products.
- Smooth Finish: Dries to a smooth, sandable texture that integrates perfectly with the wall surface.

- Internal Walls: Repairing hairline cracks in living rooms, bedrooms, and common areas before painting.

How to Apply JSW iBlok Crack Fix (Flexible Paste)
For durable, invisible crack repair, follow these steps:
- Prepare the Crack: Open the crack into a ‘V’ groove shape (approx. 5mm wide and 5mm deep). Remove all loose material, dust, and oil. The crack must be clean and dry.
- Application: Press the JSW iBlok Crack Fix paste firmly into the crack using a putty knife or trowel. Ensure the paste completely fills the cavity and is slightly overfilled.
- Curing: Allow 24 hours for the paste to dry completely. For deeper cracks, wait longer before sanding.
- Sanding & Priming: Lightly sand the repaired area flush with the wall surface using fine sandpaper. Apply the recommended primer over the repaired area before applying wall putty or topcoat paint. Find detailed guidance on professional crack repair.
