TRUBUILD WSL 334 is a single-component, ready-to-use Styrene Butadiene Rubber (SBR) latex additive developed for high-performance waterproofing, concrete repair, and bonding applications. It is specially designed to improve the durability and adhesion of cement-based systems while enhancing resistance against water ingress, cracking, and surface deterioration. It performs effectively on both new and old construction surfaces, making it suitable for repair and renovation projects.

The product acts as a waterproofing enhancer, bond coat, and polymer modifier that improves the physical properties of mortar and cement slurry. When mixed correctly, it increases bond strength, hardness, flexural performance, and crack resistance, while helping reduce future leakage and dampness issues. Since it is chloride-free, it also supports reinforcement protection by reducing corrosion risk.
