2. A Portland-based self-leveling underlayment may be applied over it. Check with the underlayment manufacturer for suitability, application
instructions, and warranties.
NOTE: Never use solvents or citrus adhesive removers to remove old adhesive residue. Solvent residue left in and on the suboor will affect the bond
between the new adhesive and the new oor covering.
Other approved underlayments
• Self-leveling and patching compounds (latex-fortied, Portland cement-based only).
• Radiant heat oors (not exceeding 85°F [29°C] and approved by the manufacturer for the use of their product with resilient vinyl ooring applications).
• Gypcrete can be utilized when necessary due to radiant heat and in high-rise buildings. Gypcrete must be sealed using manufacturer-approved acrylic latex
primer to stabilize the surface for adhesive bond. All issues with gypcrete cracking, crumbling, powdering and resulting in the release of adhesive bond are
NOT warranted by the manufacturer.
Storage and Handling
• It is important that ooring products maintain proper temperature before, during and after installation in order to minimize dimensional changes.
The suboor, all ooring material, and the adhesive must be conditioned at a constant temperature between 65°F (19°C) and 85°F (29°C) for 48 hours prior
to, during and 48 hours after installation. Thereafter, maintain a room temperature between 55°F (13°C) and 85°F (29°C).
• Always store and transport exible vinyl ooring on a at surface in neat stacks to prevent warping. Never store the cartons upright or in moist, dusty rooms
or in places with extreme temperatures. Cartons should be evenly stacked and away from any heating/cooling ducts or direct sunlight.
Suboor and Wall/Door Preparation
• The oor must be clean, smooth, at and dry. Remove all foreign substances such as wax, grease, dirt, construction markings and contaminants, and any
substance or chemical that would interfere with a good bond. Fill all holes and cracks with a latex-fortied, Portland cement-based patching compound.
Sand high spots to eliminate the possibility of telegraphing. Prime oor, if needed, with a manufacturer-approved latex primer to prevent over-absorption
of adhesives, dust containment, and to ensure a better bond of the adhesive to the suboor.
• Any unevenness of more than 1/8 inch over a 10-foot span (3 mm over a length of 3 m) must be leveled out. Remove bumps in the suboor by sanding or
scraping. The same applies to unevenness of more than 1/32 inch over a length of 1 foot (1 mm over a length of 30 cm).
• Fill any low spots in the suboor and cracks or gaps 3/16 inch (4 mm) in width or greater with a Portland cement-leveling compound.
• Ceramic tile and embossed ooring exceeding the above requirements will require skim coating with a Portland cement-based patch to avoid bottom-up
pattern telegraphing.
• Remove any existing oor molding. Removal of wall baseboards is optional, provided a quarter round is installed to cover the required expansion gap.
• Undercut doorjambs, allowing the rigid luxury vinyl ooring to slip under the doorjamb/case molding.
• Sweep the suboor clean. The oor must also be free of all contaminants.
Job Site Conditions
• It is recommended that resilient oor covering installation shall not begin until all other trades are completed.
• Areas to receive ooring shall be clean and fully enclosed. Temperature range of 55°F (13°C) and 85°F (29°C) should be maintained during, before and after
the installation.
• Adhesive working and open times vary based on job conditions, substrate, temperature and humidity.
Temperature – Radiant Heat
• Radiant heated substrates must never exceed 85ºF(29ºC) surface temperature.
• Several days prior to installing resilient products over newly constructed radiant heated systems, make sure the radiant system has been on and operating
at maximum temperature to reduce residual moisture within the concrete.
• Three days prior to installation, lower the temperature to 65ºF(18ºC), and 24-hours after installation, gradually increase the temperature in increments of 5ºF.
• After continuous operation of the radiant system, ensure the surface of the oor does not exceed 85ºF(29ºC).
Releasable Full Spread Installation Instructions
• Prepare the substrate in accordance with the substrate preparation instructions above.
• Porous surfaces require priming, using the manufacturer-approved acrylic latex primer.
• Measure the room and determine starting point. Measure tile width and determine if last tile in row will measure less than half a tile width. If so, trim the
starting tile by the amount needed to result in a nal tile of half width or greater.
• On the starting wall, set a chalk line to ensure a square installation.
• Using a 3/8-inch nap paint roller, apply the manufacturer approved pressure-sensitive adhesive after fully saturating the roller. Always apply an even and
heavy coat with an orange peel texture. Before laying the exible vinyl ooring, wait for the adhesive to become dry to the touch, ensuring no adhesive
