Vetobond AB432 is an acrylic, polymer-based bonding agent and cement modifier designed to be used as a bonding aid, curing agent, and to gauge liquid for cementitious systems. The product is resistant to hydrolysis and can therefore be used for external applications. Vetobond AB432 is a milky liquid that first turns purple when applied on concrete then becomes clear once it dries. It can be applied directly from the bottle or pail onto concrete substrates using a brush, roller, or spray
