Water based construction adhesive having improved moisture resistance useful for binding two substrates

A method for adhering two substrates together comprising the step of applying to at least one substrate, a construction adhesive comprising a polymer made by emulsion polymerizing a mixture of monomers consisting essentially of:

• (a) 20 to 60%, based on the total weight of monomers, soft acrylic ester monomers
• (b) 20 to 60%, based on the total weight of monomer, hard monomers
• c) 1 to 4%, based on tie total weight of monomers, ureido containing polymerizable monomers
• (d) 1 to 4%, based on the total weight of monomers, vinyl base monomers
• (e) 1 to 8%, based on the total weight of monomer, polymerize functional acids,
• and compounds selected from the group consisting of catalyst, chain transfer agents, and optionally, compounds selected from the group consisting of dispersants, defoamers, tackifiers, freeze-thaw inibitors, fillers, thickeners and mixtures thereof,
• to form a water-based adhesive having a water-based adhesive having a viscosity of between 5,000 and 1,000,000 cps,
• and subsequent to application of the adhesive, contacting the two substrates for bonding.
