SBR LATEX is an admixture that is designed as an integral adhesive for cement bond coats, mortars and concrete to improve bond strength, flexibility, waterproofing and chemical resistance.

In stock and available for next day delivery, Strucsol's SBR Latex contains neat ingredients with no watering down, making sure you get the best performance possible. 

SBR (Styrene-Butadiene Rubber) latex is highly valued in the construction industry for its ability to enhance the performance of building materials. Here’s how it’s specifically used:

Applications and uses of SBR Latex

1. Concrete Modification

• Improved Flexibility: SBR latex is added to concrete mixes to increase flexibility, reducing the risk of cracking under stress or temperature changes.
• Enhanced Adhesion: It improves the bond between new and old concrete, making it ideal for repair work.
• Waterproofing: Reduces permeability, making concrete more resistant to water ingress and corrosion.

2. Mortar and Grout Additive

• Strength and Durability: Used in mortars and grouts to improve tensile strength and resistance to abrasion.
• Crack Resistance: Helps prevent shrinkage cracks in tile adhesives and rendering.

3. Waterproofing Membranes

• Roofing and Basements: SBR latex is a key component in liquid-applied waterproofing membranes for roofs, balconies, and basements, providing a seamless, durable barrier against water.

4. Repair and Restoration

• Structural Repairs: Used in repair mortars for damaged concrete structures, bridges, and tunnels to restore integrity and extend lifespan.
• Surface Coatings: Applied as a protective coating to concrete surfaces to guard against chemical attack and weathering.

5. Bonding Agent

• Multi-Layer Applications: Acts as a bonding agent between layers of screeds, renders, and concrete overlays, ensuring strong adhesion.

SBR latex is favored in construction for its ability to improve durability, flexibility, and water resistance, making it a go-to solution for both new builds and repairs.

Features & Benefits

• Reduces cracking through increased mortar flexural strength
• Increases wear resistance under rubber wheeled traffic
• Improves bond strengths to hardened concrete
• Increases durability during freeze/thaw cycles
• Increases mortar tensile strength
• Increases water resistance ( for tanking )
• Increases resistance to salt attack in cement based renders.

Applications

• Waterproofer for cement based renders
• Salt inhibitor for renovation renders
• Toppings, repairs, and levelling concrete surfaces
• Thin sets, terrazzo, stucco, and bonding coats
• General reconstruction work/latex modified overlays
• Bridge decks, highways, and parking decks

Specifications / Compliances

• Complies with ASTM C1059-86, Type II
• Canadian MTQ
• SBR LATEX is classified by The American Concrete Institute as a non-re-emulsifiable bonding admixture
