Bostik Fast Tack Wood Flooring Urethane Adhesive

Surface Preparation

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 is 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).

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.

Application

Ensure starter rows are firmly in place by wedging or face nailing. Once initial rows are secure, use adhesive in a Wet-Lay or Walk-On-Work method of installation.

WET-LAY METHOD: Apply adhesive to substrate with suitable trowel. Immediately place flooring onto “wet” adhesive.

WALK-ON-WORK METHOD: Apply adhesive to substrate with suitable trowel and allow it to develop tack (refer to Temperature/Humidity Chart). Install flooring onto “tacky” adhesive.

Curing

Keep from light-foot traffic until adhesive is fully cured, usually 8 to 12 hours.

Clean-Up

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.
