SPECIFICATION COMPLIANCE

• Meets all requirements of the 1990 Clean Air Act

• Is a ƒDomestic End Product as defined in Buy American Act, Title 41 USC 10

HBR XL is an inert material, and therefore, it is physically and chemically compatible with virtually all known hot-pour and cold-applied sealants including self-leveling types.

INSTALLATION

Prior to installing HBR XL, the joints should be cleaned per the sealant manufacturerƒs recommendations. Thoroughly remove any concrete form-release agents, curing compound reside, laitance or any foreign materials. To ensure a good sealant bond, joints must be clean and dry when the new sealant is installed. Air compressors used for this purpose must be equipped with traps for removal of oil and moisture. Install HBR XL with a blunt tool at the depth recommended by the sealant manufacturer.

Care should be taken not to puncture, over-compress or stretch HBR XL during installation. Proper size selection is important as it controls the depth of the sealant bead. It must be oversized (25-50%) to fit tightly into the joint and functions as a bond-breaker to prevent back-side adhesion of the sealant. Sealant compatibility should be confirmedby the sealant manufacturer. Compatibility characteristics of sealants in contact with sealant backings can be determined by ASTM C 1087 test method.
