GET FREE SAMPLE KOVARA High moisture conditions within a concrete slab and tight project schedules post challenges to building owners, general contractors and flooring installers. Practically all floor coverings require low moisture conditions within the concrete before allowing warranted flooring installation. This is particularly true for flooring projects in typically high moisture conditions, such as basement flooring installation. If a floor is not sufficiently dry, "shot blast and seal" moisture mitigation systems require extensive surface preparation followed by layers of coatings and cementitious flooring underlayment. Until now, contractors and installers were faced with two equally unattractive alternatives: wait and risk project delays while the floor dries, or install expensive multi-component moisture mitigation systems. Kovara® provides an ideal basement flooring option for superior moisture suppression at a modest cost, and is quick and easy to install. Kovara® flooring underlayment suppresses moisture mitigation from the top surface of the concrete for internal relative humidity levels up to 95% (ASTM F2170). Its low moisture transmission rate of 0.084 (ASTM E96) means it essentially blocks moisture to the flooring system. VERSA-SHIELD-VIDEO-2014 HOW IT WORKS INSTALLATION IDEAL FOR.. Kovara®’s polymer film coating on the underside of the patented fiberglass reinforced membrane provides moisture suppression. The unique mineral top coat allows the installer to adhere the chosen floor covering to the Kovara® surface. Kovara®’s dimensional stability allows it to remain flat on the slab, so gluing Kovara® flooring underlayment to the slab is never required.

A dimensionally-stable, four-ply composite product, engineered as a moisture suppression system for all grades of concrete. Specify in Division 9, Section 0961 09 Kovara®Seam Tape is designed to be used with Kovara® Flooring Underlayment to ensure low moisture permeability along seams. Tape Width x Length = 2 inches wide x 180 feet long Store Kovara® Seam Tape indoors in a cool, dry area at temperatures between 60° F (16°C) and 80° F (27° C) Kovara® Approved Floor Coverings Bulletin HVP-1O1 Kovara® has been approved for use with a variety of floor coverings to suppress moisture vapor in concrete slabs as noted in our literature and supported by our Limited Warranty. There are thousands of floor covering options in the market, with new products constantly being introduced. It is not possible for us to individually evaluate all of these products. Numerous moisture remediation products are on the market available to address moisture problems in concrete sub-floors. No one product is the perfect solution for every application. Each product category and individual product is only one part of a total flooring system. Job site conditions, concrete subfloor conditions, subfloor moisture conditions, finished flooring selected, installation processes and products, commercial maintenance products and procedures, environmental conditions and how the finished flooring will be used can all impact the success of the total installation. Kovara® is a moisture vapor retardant membrane that resists moisture movement due to its polymer film base. Its patented fiberglass reinforced layer is designed so that Kovara® lays flat on your floor. Kovara® membrane and Kovara® tape have no components known to cause finished flooring to expand, contract, or otherwise change dimension. Because Kovara® is not adhered to an underlying floor slab, Kovara® will not provide vertical restraint to finished flooring that has a propensity to move. Therefore, Kovara® cannot prevent finished flooring from cupping, peaking, curling, or other vertical movement after installation of Kovara®. Before using Kovara® user shall determine the suitability of the product for its intended use and user alone assumes all risks and liability whatsoever in connection therewith. Always check with the finished flooring and adhesive manufacturers for approved product use, application instructions and best practices. For Kovara® installation, please refer to Halex Bulletin HVP-102 Installation Instructions. Initial Maintenance: When the finished flooring has been completely installed, it is imperative to comply with the adhesive and flooring manufacturers’ specification for curing time. This is particularly important with VCT, SVT and LVT installations. This can require up to 5 days (120 hours) for full curing of the adhesive before any maintenance is performed. Failure to do so may result in water damage to the adhesive and seams of the finished flooring. This damage is not the responsibility of Halex Corporation. Kovara® Moisture Barrier Saves Time and Money on Planned Floor Removal Kovara® Flooring Underlayment is a Moisture Barrier designed to prevent and solve moisture vapor issues when installing flooring over concrete. Kovara® Flooring Underlayment can also be used to act as an ideal underlayment for jobs that by design will likely be replaced or renovated on a shorter time horizon than the typical lifetime of the finished flooring. If you suspect the finished flooring will be replaced due to tenant remodeling, multi-use flexibility, or interior design requirements, Kovara® can save you time and money. • Because Kovara® is not adhered to the concrete sub floor, the finished floor can simply be lifted up and removed. • Little or no expensive and time consuming additional concrete subfloor preparation (like shot blasting, stripping, scraping) would be required to install your new floor. • No harsh chemicals will be required, and the demolition waste of a traditional replacement job can be eliminated. Keep in mind….. Kovara® Flooring Underlayment is not only effective in moisture mitigation, but is also a real benefit to our environment and your project budgets.
