What is SBR Bonding Agent?

SBR (Styrene-Butadiene Rubber) is a liquid polymer used as a bonding agent, waterproofing additive, and strength enhancer in cementitious applications. It improves adhesion, flexibility, and resistance to water and chemicals.

Key Features:

• Enhances bonding strength between old and new concrete
• Improves waterproofing properties
• Increases flexibility and crack resistance
• Reduces shrinkage and permeability
• Ideal for repair, plastering, and flooring applications

How to Use SBR Bonding Agent?

1. Mix SBR with water and cement to form a slurry.
2. Apply the slurry as a bonding coat on the prepared surface.
3. For repairs, mix SBR with mortar and apply over the slurry.
4. For waterproofing, mix SBR with cement and apply in multiple coats.
5. Allow proper curing before subjecting to heavy loads.
