DARAWELD® BA3 Concrete Bonding Agent

DARAWELD® BA3 is a high-performance, liquid, water-based dispersion formulated on a styrene-acrylic polymer system. Designed specifically for the construction industry, it acts as a powerful admixture to modify cementitious mixes, significantly improving their mechanical and physical properties. By integrating this polymer into mortar, concrete, or grout, contractors achieve superior adhesion to existing substrates and enhanced structural integrity.

The primary benefit of DARAWELD® BA3 is its ability to dramatically increase bond strength, tensile strength, and flexural strength. This makes it an ideal solution for repair works, where new cementitious materials must bond securely to old, often rough or contaminated, concrete surfaces. Additionally, the polymer system provides excellent resistance to abrasion, aggressive chemical attacks, and water or vapor transmission, ensuring long-term durability in harsh environments.

• Enhanced Bonding: Creates a strong mechanical and chemical bond between new and old concrete or masonry.
• Improved Strength: Increases tensile and flexural resistance, reducing the risk of cracking under stress.
• Chemical & Water Resistance: Protects against abrasion, chemical exposure, and moisture ingress.
• Easy Application: Available as a ready-to-use liquid that mixes easily with water or cement.
• Versatile Use: Suitable for floor screeds, wall plastering, tile adhesives, and structural repairs.
