STEP 4: SUB-FLOOR PREPARATION
All Sub-floors Must Be:
■
Dry and free of wax, paint, oil, and debris. Replace any water-damaged or delaminated sub-flooring or underlayments.
Scrape smooth and sweep prior to installation.
■
Level/flat within 3/16" over 10' and/or 1/8" over 6'. If sub-floor is concrete and a leveling compound is needed,
use Portland based leveling compounds such as Parabond or Ardex. Follow the manufacturer’s recommendation for
applying the leveling compound. Any area containing the leveling compound must be completely dry before proceeding
with the installation of the wood floor. If sub-floor is plywood or equivalent, high areas or joints can
be sanded flat.
■
If plywood or equivalent, sub-floor must be structurally sound prior to installation. Sub-floor must be properly secured
with nails or screws every 6 inches along joists to reduce the possibility of squeaking after final installation.
■
Appropriate moisture tests must be performed as outlined in the “Step 5: Testing for Moisture Content” section listed below.
