| Preparing a Subfloor |
|
How much preparation the basement subfloor requires depends on its material and condition as well as what you’re installing on it. All concrete floors seem to draw moisture, passing it on to whatever is in contact, such as your new floor. So, at the least, you will need to install a vapor barrier below new flooring. Then comes the adhesive or wood depending on whether you’re gluing or nailing the new flooring down. There are numerous concrete repair products available through local building material suppliers. The best choice depends on the severity of the damage (crack, hole, slippage) and its size. In extreme cases, it may be best to remove a large section of concrete slab and replace it with a new one rather than make numerous patches. The goal is to provide a sufficiently smooth and level base for the new flooring material. Remodeling Safety Make sure you wear protective gear when working with concrete repair and leveling products. The fine dust can irritate your lung and eyes. Wear a protective breathing mask and safety glasses.
