• Moisture testing of concrete subfloors must be performed in accordance with ASTM F1869 Standard Test Method for Measuring Moisture Vapor
Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride and ASTM F2170 Standard Test Method for Determining Relative Humidity in
Concrete Floor Slabs Using in situ Probes. When installing Verarise using the FLOATING INSTALLATION SYSTEM do not install if the values are
greater than 5 lbs. /1000 ft²/24hrs per ASTM F1869 or 85 %RH per ASTM 2170. If the tests results exceed the limitations, the installation must not
proceed until the problem has been corrected.
• Tarkett does not recommend or warrant any particular product or procedure for the remediation of high moisture in concrete substrates. Several
companies manufacture products suitable for moisture remediation. We suggest you refer to the current ASTM F 710 Standard Practice for Preparing
Concrete Floors to Receive Resilient Flooring and ASTM F 3010 Standard Practice for Two Component Resin Based Membrane-Forming Moisture
Mitigation Systems for Use Under Resilient Flooring Systems.
• pH testing of concrete subfloors must be performed in accordance with ASTM F710 Standard Practice for Preparing Concrete Floors to receive
Resilient Flooring. When installing Verarise using the FLOATING INSTALLATION SYSTEM the concrete surface pH should be between 7-9.
ADDITIONAL SUBFLOOR GUIDELINES
• Many installations over existing floors produce satisfactory results. However, their success is dependent upon the condition of the existing floor
covering. Installing over certain existing flooring increases the possibility of deflection and cause separation in the joints. Note: The final decision to
cover an existing floor with new flooring rests with the flooring contractor and/or installer. Tarkett will not accept responsibility for floor failures where the
condition, type or improper preparation of the existing floor is the cause for the failure. When installing Verarise over an existing flooring follow the
recommended guidelines below.
• Ceramic, Porcelain and Natural Stone tiles must be smooth, even and well bonded with a grout line depth less than 1/16” (.625). If grout
joint depth exceeds the maximum allowable depth, fill with Portland based patching compound following manufacturer’s guidelines.
Installing Verarise over existing Ceramic, Porcelain and Natural Stone tiles is only recommended when using the floating installation
method.
• Resilient Vinyl floors must be smooth, even, non-cushioned and well bonded to the substrate.
• Strip Wood Hard Wood Floors must be smooth, even, flat, with a maximum gap width between boards of 1/16” (.625). Installing Verarise
over Strip Wood Floors is recommended when using the floating installation method, the use of ProSheet™ Plus3 is recommended. :
Follow the detailed ProSheet Plus 3 installation instructions found at www.tarkettna.com
• Heated flooring systems must be installed 2’’ below the concrete subfloor and the operating temperature must not exceed 85ºF (29.4ºC). During
installation, lower the radiant heated floor temperature to a minimum 65º F (18.3º C). This temperature should be maintained for at least 24 hours
before, during and 48 hours after completion of the installation. Gradually increase the temperature in increments of 5°F every 24 hours but do not
exceed 85°F (29.4°C).
• Residual adhesives should be mechanically removed. Do not use chemical adhesive removers or solvents. Always follow RFCI’s Recommended Work
Practices for Removal of Resilient Floorcoverings. Caution: Some resilient flooring products and adhesives contain "asbestos fibers" and special
handling of this material is required.
• Refer to ASTM F2419 Standard Practice for Installation of Thick Poured Gypsum Concrete Underlayments and Preparation of the Surface to Receive
Resilient Flooring for guidelines when pouring gypsum underlayments or preparing for use as an underlayment under Tarkett products. Follow the
Gypsum Underlayment manufacturer’s recommendations for proper application and preparation.
SUBSTRATE PREPARATION
• All substrates must be dry, clean, structurally sound, smooth and free from all existing adhesive residues.
• The substrate must be flat within 1/8” in 8’ (3.17mm in 2.4m).
• Fill and level concrete cracks, construction joints, control joints, depressions, grooves and other irregularities. Use a latex fortified, cementitious
patching compound and follow the manufactures recommendation for preparing.
• Sweep and vacuum or damp mop substrate to remove all dust and debris.
• ProSheet Plus 3 can be used if needed in on or above grade applications only. Follow the detailed ProSheet Plus 3 installation instructions found at
www.tarkettna.com.
• DO NOT SAND, DRY SWEEP, DRY SCRAPE, DRILL, SAW, BEADBLAST OR MECHANICALLY CHIP OR PULVERIZE EXISTING RESILIENT
FLOORING, BACKING, LINING FELT OR ASPHALTIC “CUT-BACK” ADHESIVE OR OTHER ADHESIVE.
• These products may contain either asbestos fibers or crystalline silica. Avoid creating dust. Inhalation of such dust is a cancer and respiratory tract
hazard. Smoking by individuals exposed to asbestos fibers greatly increases the risk of serious bodily harm. Unless positively certain that the product is
a non-asbestos containing material, you must presume it contains asbestos. Regulations may require that the material be tested to determine asbestos
content. Various federal, state and local government agencies have regulations governing the removal of in-place asbestos containing material. If you
contemplate the removal of a resilient floor covering structure that contains (or is presumed to contain) asbestos, you must review and comply with all
applicable regulations. Refer to the current edition of the Resilient Floor Covering Institute (RFCI) “Recommended Work Practices for Removal of
Resilient Floor Coverings” for detailed information and instructions for removal of resilient floor coverings
• “Refer to the Resilient Floor Covering Institute (RFCI), Recommended Work Practices for Removal of Existing Resilient Flooring for best work practices”
located on RFCI’s website at www.rfci.com
• Prior to removing, an existing floor follow the RFCI Recommended Work Practices for Removal of Resilient Floor Coverings (unless state or local law
requires other measures). If there are visible indications of mold or mildew or the presence of a strong musty odor in the area where resilient flooring is
to be removed or installed, the source of the problem should be identified and corrected before proceeding with the flooring work.
