Description
SURPRO HDWB is a high performance, two-component urethane/acrylic sealer formulated specifically to seal and protect concrete and other cementitious surfaces that are subject to the heaviest use conditions. SURPRO HDWB is semi-gloss, chemically resistant, highly durable, and cures hard within 24 hours of application. The low odor formula is designed to allow application without disruption of normal operations - ideal for areas where solvent odors from traditional acrylic or polyurethane coatings are not tolerated.
SURPRO HDWB offers enhancement of the substrate similar to solventborne sealers. In interior applications, if a more “natural”, un-enhanced appearance of the substrate is desired, SURPRO HDWB may be applied over SURTEC BOND COAT waterborne acrylic sealer. SURPRO HDWB has also shown compatibility with waterborne epoxy primers and sealers, however, any combination of SURPRO HDWB with other coatings and sealers must be tested in a mockup, either onsite or in a workshop, to guarantee compatibility and should be offered to the customer for approval.
