Sub-Floor Preparations

1. Concrete sub-floors should always be checked for moisture content prior to the installation of wood flooring.
2. Calcium Chloride Test- Moisture should not exceed 3lbs/1000 square feet with this test.
3. Do not install wood flooring if moisture levels exceed recommended level.
4. Sub-floor must be dry and free of wax,oil, paint,dust, and all other type of debris.
5. Sub-floor should be level/flat within 3/16” over 10’and/or 1/8” over 6’, if sub-floor is concrete and a leveling compound is needed.
6. If plywood is used as a sub-floor, the moisture content difference should be NO MORE than a 3% between the engineered wood floor and the plywood, and there should be NO MORE than a 2% difference between the solid wood and the plywood. All plywood must be EXTERIOR grade CDX, and plywood size for sub-floor is suggested to be no larger than ¾" by 48" x 48" and an expansion gap of no less than ¼" between sheets, and installed in an alternate pattern. (Not straight rows).
7. A suggested moisture barrier is a layer of floor tar adhesive, 15lbs asphalt felt, another layer of floor tar adhesive, and then the plywood. If the plywood is being installed over a concrete sub-floor, then nail the plywood to the sub-floor every 1- foot along the outside edge, and the same throughout the interior.
