Alvas recommends starting with North American Plywood as your wood source, or they may recommend a dealer near you. (North American Plywood: East Coast 800-759-6606 or West Coast/Midwest 800-421-1372) The wood glue and spray adhesive can be purchased at your local home improvement store.
Foam Blocks: The size and color of the foam blocks may vary slightly; variances in size and/or color will in no way hinder the functionality of the floor.
Precautions: Heavy objects (over 100lbs) cannot sit on any foam bottom floating floor for an extended period of time (more than 24hrs).
Make sure there is no water leaks or under-concrete water seepage, as no floor should be installed in any room if moisture penetration is suspected. The area must remain dry.
Upon written approval, undamaged and unopened boxes may be returned for credit, subject to a 25% restock/handling charge. Subfloor Instructions are non-returnable.
