Shelf Life Details Store in clean, dry, warm area to ensure ease of application. Shelf life is nine months from the date of manufacturing.TO RE-SEAL PARTIALLY USED CONTAINERS Close Container:Cover opened pail with 2 pieces of plastic. Secure lid tightly to pail. Carefully turn pail upside down (the 2 pieces of plastic act as “bond breakers” preventing the adhesive from bonding the lid shut)., Re-Open Container: Carefully turn pail right-side-up. Remove lid. Carefully cut and discard cured adhesive and plastic from top of pail. Any uncured material may be used. Shelf Life Type From the date of manufacturing Shelf Life (mon) 9

Best Practices for Bostik Ultra-Set HardWood Premium Wood Flooring Urethane Adhesive
Surfaces must be clean, dry and smooth
free of voids, projections, loose materials, oil, grease, sealers and all other surface contaminants. If there are any moisture-related concerns, or if solid wood is being installed, completely remove cutback adhesive residue by sandblasting, shotblasting or scarifying. When sandblasting, shotblasting or scarifying, surface texture must be similar to light broom finished concrete. The Blastrac shotblasting method of surface preparation utilizing BT#1, BT#2 or BT #3 (.017" to .028" diameter) shot is recommended. Maximum acceptable floor variation is 1/8" in 10 feet. Surface areas requiring patching or leveling should be done using a portland cement based material (contact Bostik’s Technical Service Department for recommendations).
Ensure starter rows are firmly in place by wedging or face nailing. Once initial rows are secure, use adhesive in a Wet-Lay method of installation. As you work, immediately clean any adhesive on pre-finished flooring with a soft cloth and mineral spirits. (Be careful not to harm finish.) If adhesive is cold, place pail in either a warm area or bucket of warm water to improve workability. WET-LAY METHOD: Apply adhesive to substrate with suitable trowel. Immediately place flooring onto “wet” adhesive.
Keep from light-foot traffic until adhesive is fully cured
usually 8 to 12 hours.
Once cured this is the most tenacious adhesive known to the hardwood industry. Immediately clean any adhesive on pre-finished flooring with a soft cloth and mineral spirits. (Be careful not to harm finish.) Do not allow mineral spirits to sit on hardwood surface. Clean tools and equipment with mineral spirits before adhesive cures. Wear rubber gloves when using adhesive. Removal of cured adhesive from pre-finished flooring, skin, tools and equipment is extremely difficult. Use Bostik #94 Hand Cleaner for removal of uncured adhesive on skin.
TROWEL CLEAN-UP TIP: Before use, cover areas of trowel that are not used to spread adhesive with clear packaging or gray duct tape. After use, simply tear off tape before material cures. Clean remainder of trowel with a dry cloth or mineral spirits.
