Description
SURPRO 44 MATTE is a high performance, low gloss, 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 44 MATTE’s fast cure time makes it especially suitable for retail and commercial applications requiring a quick return to service. SURPRO 44 MATTE is compatible with acrylic floor polishes as topcoats and is resistant to heavy duty commercial strippers, therefore it makes an excellent permanent base coat
sealer for floor polishes over concrete. 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 44 MATTE 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 44 MATTE may be applied over SURTEC BOND COAT waterborne acrylic sealer. SURPRO 44 MATTE has also shown compatibility with waterborne epoxy primers and sealers, however, any combination of SURPRO 44 MATTE 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.
