JSW iBlok Multi Repair Polymer (MRP) – SBR Latex for Waterproofing & Repairs

JSW iBlok Multi Repair Polymer: Multipurpose SBR Polymer for Repair & Bonding

JSW iBlok Multi Repair Polymer is a high-performance, multipurpose SBR (Styrene Butadiene Rubber) latex-based additive designed to enhance the strength, durability, and waterproofing properties of cement mortar and concrete. It is the professional’s choice for modifying standard cement mixes to achieve superior adhesion, flexibility, and crack resistance.

Whether you are repairing a leaking roof, bonding old concrete to new, or creating a flexible waterproof mortar for bathrooms, JSW iBlok Multi Repair Polymer is essential. It acts as a bonding agent, an admixture, and a protective coating, making it the most versatile product in the iBlok waterproofing range.

Why Choose JSW iBlok Multi Repair Polymer?

Unlike using plain water in cement mixes, adding this polymer creates an entirely new material with enhanced properties:

• Superior Bonding: Creates an extremely strong bond between old and new concrete/plaster, preventing cold joints and delamination.
• Waterproofing: When mixed with cement, it creates a flexible, impermeable slurry ideal for internal waterproofing applications like sunken slabs and masonry repairs.
• Crack Reduction: The polymer reduces shrinkage and provides flexural strength, minimizing the chance of new cracks forming in the repair mortar.
• Durability: Increases the abrasion resistance and chemical stability of the repair layer.

Key Features of JSW iBlok Multi Repair Polymer

• Versatile Use: Functions as a binder, additive, and primer coat.
• High Solid Content: Ensures maximum performance and effectiveness with minimal mixing quantity.
• Non-Re-emulsifiable: The polymer does not dissolve back into water once cured, guaranteeing permanent water resistance.
• Excellent Adhesion: Bonds to a wide variety of substrates including masonry, wood, and concrete.

Recommended Application Areas

This multipurpose polymer is critical for:

• Damp Patch Repair: Mixed with cement to create a mortar for patching damp spots and minor leakages.
• Bonding Coat: Applying a slurry of polymer and cement to old concrete before pouring new screed or plastering.
• Sunken Slab Waterproofing: Creating a dense, flexible mortar layer in bathrooms and balconies.
• Grout Filling: Repairing non-moving joints in masonry and tiles.

How to Use JSW iBlok Multi Repair Polymer

The application method depends on the required function:

1. Bonding Coat (For plaster/screed repair): Mix 1 part polymer with 1 to 1.5 parts cement until a thin slurry consistency is achieved. Apply this slurry with a brush to the prepared substrate. Apply the repair mortar or new plaster while the bonding coat is still tacky (wet-on-wet).
2. Repair Mortar (For patching cracks/holes): Mix cement and fine sand (3:1 or 2:1 ratio). Replace 10-20% of the water required for the mix with **JSW iBlok Multi Repair Polymer**. Use the modified mortar for structural and waterproofing repairs.
3. Surface Preparation: Ensure the surface is clean, sound, and free from loose material. Chip away unsound concrete or plaster before applying the polymer-modified mix. Get detailed guidance on using polymer additives for concrete repairs.

Frequently Asked Questions (FAQ)

Q: Is this product ready to use?
A: The polymer liquid itself is ready to use, but it must be mixed with cement and/or sand to perform its repair function.

Q: Does this replace the plaster/sand?
A: No, it is a polymer additive that replaces part of the mixing water. It enhances the properties of the plaster, cement, or mortar mix.

Q: Can I use this with ready-mix wall putty?
A: It is generally used with cement-based products (like cement putty or mortar) to improve their strength and waterproofing. Consult the technical sheet for specific ready-mix compatibility.
