8303 CrownShield® MVB
Description
8303 CrownShield™ MVB can be used as a single primer coat negative side moisture vapor barrier suitable for various types of concrete. The low viscosity formula not only promotes deeper concrete penetration for superior substrate adhesion but also generates a higher propensity for sealing and blocking moisture drive up to 25 lbs per 1000 ft2 and 99% relative humidity. It is intended for use when high moisture levels are present in the concrete which may cause loss of bond of moisture-sensitive flooring systems, including impervious and semi-pervious flooring, such as, epoxy, polyaspartic, polyurethane, carpets, vinyl tiles and covering, tile, wood floors, etc. It meets or exceeds ASTM F3010 Standard Practice for Two-Component Resin Based Membrane-Forming Moisture Mitigation Systems for Use Under Resilient Floor Coverings. It is VOC Compliant in all states and provinces in North America.
Typical Uses
- Floors containing high-moisture level
- Beneath moisture sensitive flooring systems (carpet, VCT, tile, laminates and wood)
Benefits
- Complies with USDA, FDA, FSMA. See Crown Polymers Technical Bulletin: 3 Food and Beverage Compliance.
- LEED requirements. See Crown Polymers Technical Bulletin: 5 LEED information
- Cures to an inert finish. See Crown Polymers Technical Bulletin: 2 VOC Compliance
