Weld-Crete Concrete Bonding Agent – 1 Gallon

Weld-Crete Concrete Bonding Agent is a premium, latex-based adhesion promoter designed to maximize the bond strength of Portland cement mixes, mortars and repair overlays. Its white, high–viscosity formula penetrates and seals porous concrete surfaces, ensuring patching materials and new concrete layers adhere firmly and uniformly. Ideal for interior or exterior repair work, this one–gallon can delivers dependable performance on floors, walls, driveways and structural elements.

Whether you’re performing patch repairs, leveling a slab or installing a thin-set overlay, Weld-Crete reduces peeling, flaking and undercutting by creating a tough, flexible interface. Simply apply with a brush, roller or spray, allow to tack, then place your cementitious mixture for a professional-grade bond that stands up to freeze-thaw cycles and moisture exposure.
