Kovara® Moisture Protection

Formerly VersaShield

Moisture barrier – protection for flooring materials and adhesives against moisture and relative humidity

Kovara moisture barrier is laid above concrete floor slabs and below floor coverings to protect concrete, flooring materials and adhesives from staining, warping or mold that may result from water vapor emissions and alkaline salts infiltrating through the concrete slab.

A three-layer composite construction, Kovara has an HDPE bottom layer for moisture protection, glass mat middle layer for dimensional stability, and gray mineral top layer to enhance adhesive bond.

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
