Weld-Crete 200® – High-Performance Concrete Bonding Agent
Weld-Crete 200® is a high-performance concrete bonding agent formulated with polyvinyl acetate (PVA) homopolymer, designed to provide powerful, long-lasting adhesion between new concrete, plaster, or cementitious mixes and existing substrates. It creates a continuous green bonding film that ensures a durable, non-deteriorating bond with excellent flexibility and strength.
Engineered for professional construction and repair works, Weld-Crete 200® offers an extended open time, allowing greater flexibility when installing reinforcement steel, formwork, or placing concrete. It is non-toxic, freeze-thaw stable, and suitable for a wide range of structural and architectural bonding applications.
