Specweld A Ready-To-Use, Rewettable Polyvinyl Acetate (Pva)

SpecWeld is a ready-to-use, re-wettable PVA emulsion bonding agent that bonds new concrete, underlayments, masonry, stucco, and terrazzo to concrete surfaces

SpecWeld works as both a primer/bonding agent and a bonding admixture for cement-based mortars and stucco, recommended for interior and/or exterior use where the surface won't see constant moisture, hydrostatic pressure, or continuous water saturation.
