  • 56 sq. ft. per bag at 1/16”; 200 - 250 sq. ft. (per bag at a skim coat)

  • Provides a smooth surface over a variety of substrates; Engineered to withstand 100% RH; unlimited moisture and water; ARDEX WeatherProof Technology; Suitable for installation at temperatures as low as 40°F (5°C); Non-sanded - install from a true featheredge up to 1/2” (12 mm)

  • ARDEX MRF will bond to standard absorbent concrete and wood without the use of a primer, as well as to certain nonporous substrates, including burnished concrete, terrazzo and ceramic, quarry and porcelain tiles. Gypsum and epoxy coating systems must be primed as detailed below: Gypsum: If the substrate is a gypsum underlayment that will not be removed, double priming of the gypsum is necessary to consolidate what may be a dusty surface prior to installing ARDEX MRF. Make an initial application of ARDEX P 51™ Primer mixed with 3 parts water, and apply using a soft push broom. Do not leave any bare spots. Remove all puddles and excess primer. Allow thorough drying such that the film of primer does not re-emulsify in water (approximately 1 to 3 hours) before proceeding with the second application of ARDEX P 51 diluted 1:1 with water. Allow thorough drying to a clear, thin film (min. 3 hours, max. 24 hours). Epoxy Coating Systems: Epoxy coating systems must be primed with ARDEX P 82™ Ultra Prime. Follow the mixing instructions on the container, and apply with a short-nap or sponge paint roller, leaving a thin coat of primer. Do not leave any bare spots. Back roll with a dry roller to remove excess primer. ARDEX P 82 should be applied within 1 hour of mixing. Allow primer to dry to a thin, slightly tacky film (min. 3 hours, max. 24 hours). Follow the coverage instructions in the ARDEX P 82 technical data sheet

  • DO NOT OVERWATER! Under no circumstances should ARDEX MRF be installed over any moving joints or moving cracks. All existing expansion joints, isolation joints and construction joints, as well as all moving cracks, must be honored up through the underlayment and flooring

  • Recommended Tools: ARDEX T-2 Ring Mixing Paddle, mixing bucket, margin trowel, steel trowel, and a 1/2” (12 mm) heavy-duty drill (min. 650 rpm)

  • While ARDEX MRF is unaffected by water, the surface of the concrete must be dry during application of the ARDEX MRF

  • INSTALLATION METHOD: Standard floor coverings such as ceramic tile, VCT, sheet vinyl and carpet can be installed approximately 30 minutes after installing a skim coat application of ARDEX MRF (70°F / 21°C). If installing wood flooring, or if a highperformance adhesive such as an epoxy or urethane will be used, allow the ARDEX MRF to cure for 16 hours. All flooring adhesives that are compatible with concrete are compatible with ARDEX MRF. It is important to note that many different types of adhesives are used to install floor coverings, and their absorbency into cementitious substrates can vary significantly. If it is found that the adhesive being used is drying more quickly over the ARDEX MRF than over adjacent concrete, we recommend that the surface of the underlayment be primed with ARDEX P 51 diluted 1:3 with water. Allow the primer to dry thoroughly (1 - 3 hours), and proceed with the installation of the adhesive. The use of the primer will even out the open time of the adhesive without affecting the bond or the longterm performance. Please note that this application is for interior areas that do not have excessive moisture
