Bostik EFA Elastomeric Flooring Adhesive Bostik EFA is a one part, trowel applied, moisture cure urethane adhesive that does NOT contain water. Once cured, EFA is waterproof and is not adversely affected by exposure to moisture or water. EFA elastomeric characteristics allow the adhesive to move with the wood as it expands and contracts over the life of the floor.
Note: This produt is best used on raised foundations and on top of plywoods or second story. If your slab floors are in dry and good condition, you can use this product to directly install your wood flooring on slab. This product is perfect with Bostik MVP as a two part sealer and glue. Use a 3/16" trowel for installing with this product. Do not leave buckets unopened for long period of time. If you are done with a portion of your job, and wish to use the balance of glue at a later date, be sure to cover it with aluminum foil or a plastic wrap. Doing so, will give it a longer shelf time. Store at a cool and dry area till ready to reuse.
