Step 2 · Prepare Subfloor

Sweep and vacuum the subfloor thoroughly to remove all dust and debris. Check for any high spots or low spots; use a leveling compound to fill low areas and a floor scraper or sander to remove high spots. Ensure the subfloor is completely dry, especially if it's over a crawl space or basement. Hammer down any loose nails or screws. For some installations, a moisture barrier may be required.
