SN-SBR Latex — Full Technical Details
Product Description Overview
⌄
SN-SBR Latex is a premium modified styrene-butadiene rubber (SBR) based binder formulated with advanced elastomeric latex technology. It is engineered as a high-performance bonding agent for concrete and mortar, especially in demanding repair applications—improving the interfacial bond between old and new concrete for durable repairs.
Characteristics Key Benefits
⌄
- Enhances wear resistance for rubber-wheeled and repetitive traffic conditions.
- Minimizes drying & aging shrinkage—reducing shrinkage-related cracking.
- Improves flexibility and flexural strength to help prevent cracking from movement and thermal variation.
- Delivers excellent bond strength to concrete, plaster, masonry, and cementitious surfaces.
- Supports low water–cement ratios for improved density and resistance to water penetration.
- Promotes surface hardening for durability and abrasion resistance.
- User-friendly: easy mixing and smooth application.

Scope of Use Applications
⌄
- Basement side walls for protection against moisture ingress and seepage.
- Small roof terraces for enhanced durability and water-penetration resistance.
- Sunken areas (toilets & bathrooms), kitchen sink zones, lift pits, balconies, and eaves/sun breakers.
- Foundations and foundation walls for defense against dampness and groundwater pressure.
- Bonding new concrete to old concrete for overlays, patch repairs, and rehabilitation works.
Surface Preparation Before Use
⌄
- Clean the concrete surface where breaking/spalling is an issue. Roughen the surface and remove loose dust & particles.
- Saturate thoroughly with potable water prior to priming; remove any excess standing water.
Coverage Consumption
⌄
- As a bonding agent: 7–10 sqm/kg per coat
Application Procedure Method
⌄
