Kovara® Moisture Protection

Kovara MBX

Kovara MBX protects against alkalinity and moisture in concrete slabs up to 99.5% RH and can be identified by its dark blue surface. Kovara MBX seam tape (2.5” wide and 180’ long, blue) is used to tape the seams of Kovara MBX. Kovara double-sided tape (4” wide and 100’ long, white) is used underneath the seams of regular Kovara MBX installations. The double-sided tape is also utilized in heavy rolling load installations using a box grid method.

Kovara 95

Kovara 95 protects against alkalinity and moisture in concrete slabs up to 94.9% RH and can be identified by its gray surface. Kovara 95 seam tape (2” wide and 180’ long, gray) is used to tape the seams of Kovara 95. Kovara double-sided tape (4” wide and 100’ long, white) is utilized in heavy rolling load installations using a box grid method.

Kovara AB300

KOVARA® AB 300 is a patent-pending, self-adhered, pre-fabricated moisture barrier designed to protect floor coverings from staining, warping and adhesive deterioration that may result from water vapor emissions and alkaline salts infiltrating through the concrete slab.

KOVARA® AB 300 membranes self-adhere directly to the concrete subfloor with its own specialty designed moisture and alkaline-resistant adhesive suitable in conditions up to 99.5% relative humidity. The unique adhesive bond addresses membrane movement or buckling when heavy rolling loads and heavy foot traffic are expected. The unique adhesive is protected by a split release liner until placement.

For each roll of KOVARA® AB 300 membranes, the following additional installation components are required for sealing seams:

• 1 roll of KOVARA® MBX Seam Tape
• 1-2 rolls of KOVARA® Double-Sided Tape
