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.

Epoxy paint is a popular option for concrete due to its durability and stain resistance. You can also use masonry paint, which adheres well to concrete. Acrylic paints are more affordable but not as durable. Concrete stain is another option, which is more durable than paint and won’t peel over time. 

Sealing resurfaced concrete is not an absolute necessity. However, it is recommended, and in most cases, a high-quality concrete sealer can protect the surface from stains as well as water penetration, extending the life of the resurfacing material. Some sealers are formulated to protect pigments from fading due to UV exposure. Sealer tends to enhance the colors in decorative resurfacing applications, making them more vibrant and richer compared to the duller, more faded appearance of concrete colors without sealer.

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.
