Exterior paint finishes come in a variety of options, but for concrete, your best bet is to go with an eggshell, satin, or semi-gloss latex paint. All three options are more durable than matte finishes and should help hide imperfections on your home’s concrete surface.

The actual moisture level that is acceptable for your concrete floor depends on what primer or flooring material you plan to install above it. For this reason, you should check the manufacturer’s instructions for the exact details.

Generally, the moisture levels should be 3.5% to 4.5%, although it does vary. Some products can handle higher levels of moisture, so you should always test your concrete before purchasing your flooring materials.

Yes. So-called “floating” cork floors can be installed over concrete subfloor, though a polyethylene vapor barrier is required. This type of installation is achieved using the glue-down tiles, which are trickier for a DIY approach, so consider calling a professional to help you if you’re planning to install your cork floor over concrete. 

As with anything you buy, be wary of prices that seem too good to be true. Some low-cost flooring products can contain chemicals that release harmful VOCs (volatile organic compounds) in the form of fumes that can be inhaled or dust that can cause skin conditions.

Even good-quality products can be dangerous for DIY-ers who don’t take proper precautions. Always carefully read manufacturer instructions and wear the recommended protective gear when working with paints and other chemicals. You can also hire a local garage flooring pro with the experience and equipment needed to perform the installation safely with no lingering fumes or debris.
