You should sand concrete before painting, as it helps remove any irregularities and pieces that stick out from the surface. This not only helps the paint look better but it prevents any unwanted water absorption.

No, you cannot permanently seal concrete. The porous nature of concrete means that it’s always vulnerable to water intrusion and staining, even under the best sealants. Although some concrete sealing products can last for a long time, a genuinely permanent concrete seal remains elusive.

The lifespan of stained concrete can range from five years to a lifetime, depending on the type of stain used and how well it is maintained. Acid-based stains penetrate the concrete and can last 20 years or more, while water-based stains are less durable and may last around five years, especially on outdoor surfaces exposed to UV light and weather. To preserve the color and extend the life of the finish, stained concrete should be properly sealed and then resealed every three to five years. Factors like foot traffic, climate, and proper initial application also affect its longevity.

When you are laying hardwood flooring—or any other material that does not flex well with humidity—you will want to check the moisture level of your subfloor before proceeding. Flooring like luxury vinyl tile and bamboo performs better than more rigid materials in environments where moisture might be present. However, thorough testing is always an excellent preventative measure to control and monitor water in your home.
