GLUE-DOWN INSTALLATION INSTRUCTIONS
Maximum adhesive working times: Urethane adhesive (not included) - 60 minutes. When not in
use, keep the adhesive container tightly closed to prevent thickening. Thickening will cause difculty
in spreading the adhesive.
• Open times and curing times of ALL adhesives vary dependent upon suboor porosity, air
movement, humidity and room temperature. Urethane adhesive has a shortened working time in
high humidity environments, whereas the polymeric resin adhesives will be lengthened. In areas
of low humidity, open time will be longer with urethane adhesives. Adjust the amount of adhesive
spread on the suboor accordingly. The adhesive should not be applied if suboor or room
temperature is below 60°F.
• Hold trowel (not included) at a minimum 45° angle rmly against the suboor to obtain a
40-60 sq. ft. per gallon spread rate. The trowel will leave ridges of adhesive and very little adhesive
between the ridges. This will allow you to still see the chalk lines between the ridges and provide the
recommended spread rate.
• For additional application instructions, follow the recommendations on the adhesive container.
• Proper ventilation within the room must be provided. An electric fan is helpful.
• Rolling is not required, but if desired, DO NOT do so until the adhesive has cured for two hours.
•
During the installation, occasionally remove a piece of ooring from the suboor and inspect the
back for proper adhesive transfer. Adequate adhesive transfer is necessary to ensure sufcient
holding strength.
• If the adhesive skins over and fails to transfer, remove and spread new adhesive to achieve proper
bonding.
Note: Clean adhesive from the surface of the oor frequently. DO NOT use painter’s tape before
adhesive is removed from the surface. Use clean towels, changed frequently, to prevent haze and
adhesive residue.
• To eliminate minor shifting or gapping of product during installation, use painter’s tape to hold the
planks together. After installation is complete, remove all of the painter’s tape from the surface of the
newly installed ooring. DO NOT let the tape remain on the ooring longer than 24 hours. Avoid the
use of masking or duct tape, which leaves an adhesive residue and may damage the nish.
• If necessary, use weights to atten planks with bows until adhesive cures in order to prevent hollow
spots. Planks that cannot be attened should be cut in length to reduce the bow, or not used.
• Be sure not to spread adhesive too far ahead of your work area.
• Avoid heavy foot trafc on the oor for at least 24 hours. Lift the furniture or xtures back into place
after 24 hours.
