Waterproofing & Moisture Control


Mitigate the destructive effects of moisture vapor emissions with these great solutions.


One-component waterproof primer for priming porous/absorbent and non-porous subfloors and for rigidifying soft subfloor surfaces. WAKOL PU 280 Moisture Barrier is a premium moisture barrier for “green” concrete slabs and for concrete and offers two levels of moisture protection. 

  • Zero VOC
  • Fast curing
  • Solvent and water free
  • Not affected by water when cured
  • No mixing required
  • Approved for radiant heated floors
  • Easy to spread
  • Excellent coverage
  • One coat will block moisture up to 12 lbs. / 1000 sq.ft. / 24 hours or up to 90% rH (ASTM F 2170-02). 
  • Two coats will block moisture up to 18 lbs. / 1000 sq.ft. / 24 hours or up to 98% rH (ASTM F 2170-02).  


Planiseal VS is an alkali-resistant, two-component, 100%-solids epoxy coating that effectively stops moisture-related problems with floor coverings. In addition, Planiseal VS expedites floor-covering installations by eliminating the traditional wait time required for new concrete slabs to reach moisture levels suitable for installations.

  • Compliant with ASTM F3010 
  • Can be installed directly over clean concrete without mechanical profiling
  • No moisture testing required
  • Alkali-resistant, two-component, 100%-solids epoxy coating that effectively stops moisture-related problems with floor coverings
  • Moisture vapor emission rates (MVERs) of up to 25 lbs. per 1,000 sft per 24 hours are reduced to below the limit of 3 lbs. per 1,000 sft required for many types of finished flooring, when the designated film thickness is applied
  • Applied in a single-coat application system, offers low viscosity with high-density resins that effectively reduce MVER by penetrating deep into the substrate and effecting consolidation well beneath the surface
  • May be used to consolidate friable substrates such as weak gypsum-based underlayments or lightweight concretes before the application of floor finishes
  • Compatible with a wide number of primers and adhesives typically used with flooring installations, such as tile, vinyl composition tile (VCT), carpet, sheet vinyl, wood and other floor-finishing products

KOVARA AB 300 & DS Tape

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.  

  • Installation in a fraction of the time of fluid-applied moisture barriers
  • Self-adhered to subfloor with a specialty designed adhesive to prevent movement under heavy rolling loads and foot traffic 
  • Split adhesive release liner allows quick peel-and-stick application 
  • Reduced labor costs and improved project capacity for contractors 
KOVARA Double-Sided Seam Tape (required for installation) 

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

  • 1-2 rolls of KOVARA® Double-Sided Tape 
  • KOVARA® MBX Topical Seam Tape is not required for KOVARA® AB 300 installations
