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 improve the appearance of concrete steps, you can repair any damage, refresh the surface, and add decorative elements. For crumbling, chipping, or broken sections, consider concrete resurfacing or light repair. If the surface is intact but discolored, applying a coat of paint, stain, or concrete sealer can refresh its look; reapplying a sealer every one to two years is recommended for maintenance. For a quick enhancement, you can also add decorative items like potted plants, garden statues, lanterns, or decorative railings to spruce up the area.

While you shouldn’t use thinset mortar on its own as a floor leveler, it can work alongside other products to help level floors. For instance, you could start with a self-leveling compound, let that dry, then apply backer board with thinset mortar to help fully even out the floors ahead of laying tile.

The best time to seal your concrete driveway is sometime in the spring and fall when the temperature is above 55 degrees Fahrenheit. Keep an eye on the weather, and be sure to pick a day without rain on the forecast for at least 24 hours. Lastly, be sure you can leave the space free of foot and car traffic for the full drying time.
