AQUA SHIELD® is manufactured using our sanded AQUA PLY PLUS® treated plywood substrate.  A plasticized polyvinyl chloride film is laminated to one or both sides of the substrate with catalyzed cross-link PVA glue.  The finished AQUA SHIELD polyvinyl laminate surface acts as a moisture barrier to help prevent water absorption.  AQUA SHIELD has a lifetime limited warranty against fungal decay, against attack by termites and against manufacturing defects like delamination.
