Yes, you can seal old or existing concrete, but proper preparation is crucial. The concrete surface must be clean, dry, and free of any incompatible old sealant. To check if an old sealer is present, drip a few drops of water onto the surface; if the water is absorbed in under five minutes, it's ready to be resealed. If you plan to use the same type of sealer that was previously applied, you may not need to remove the old layer. However, if you are using a different type of sealer, the old one must be completely removed. Before applying the new sealer, thoroughly clean the concrete and repair or fill any cracks to ensure a smooth, well-prepared surface.

To preserve a concrete coating, routine maintenance should include regular sweeping and cleaning to remove debris and dirt, promptly addressing any spills to prevent staining, and applying a sealer as the manufacturer recommends. Inspect the surface periodically for any signs of wear or damage to ensure timely repairs and maintain the coating's protective qualities.

Epoxy coatings for concrete basement or garage floors are popular. These two-part resinous coatings are waterproof and highly durable, making them an ideal choice for high-traffic spaces or areas where spills are likely. However, epoxy flooring costs more to apply than concrete stains and doesn't produce a natural-looking finish.

Most concrete sealers take about one to three hours to dry. However, those that penetrate may take up to 48 hours or more to completely dry. You can find specific drying details from the manufacturer on the label.
