No. You cannot use asphalt products on concrete driveways. To seal a concrete driveway, use acrylic, epoxy, polyurethane, silane, siloxane, and silicate sealers or deep penetration sealers made specifically for concrete. Meanwhile, asphalt sealers contain refined coal tar (asphalt emulsion), water, sand, clay, polymers, and additives and are incompatible with concrete’s surface texture and higher density.

Always seal concrete stain to protect against wear and preserve the color. This applies to acid- and water-based stains but not always to concrete paint. Many paints designed for outdoor use contain ingredients designed to protect and waterproof without the need for additional sealant. Fortunately, learning how to seal concrete is something most DIY-savvy homeowners can tackle.

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, you can seal old concrete, but proper preparation is essential. Before sealing, ensure the concrete is clean, dry, and free of any old sealant. To check if resealing is necessary, place a few drops of water on the surface; if they are absorbed in less than five minutes, it's time to reseal. If you are using the same type of sealer that was previously applied, you may not need to remove the old layer. However, if you are applying a different type of sealer, the existing one must be removed. Additionally, repair or fill any cracks to create a smooth base before you begin sealing.
