Q: What is making my concrete green?

• <div><p>If your concrete stains are green in color, it indicates the presence of mold or algae&mdash;which you should address right away. If left unattended, mold will spread to other areas throughout the home. However, be careful not to disturb mold on indoor concrete surfaces and work with a <a href="https://www.angi.com/nearme/mold-removal/">local mold remediation specialist</a> for specialized care. Once free from mold and algae, seal your concrete to eliminate pores and gaps.</p></div>

Q: Can you seal old concrete or concrete that is years old?

• <div><p>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.</p></div>

Q: What maintenance helps preserve a concrete coating?

• <div><p>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.</p></div>

Q: Can I use the same sealant on asphalt and concrete driveways?

• <div><p>No. You cannot use asphalt products on concrete driveways. To <a href="https://www.angi.com/articles/what-products-should-i-use-seal-my-concrete-driveway.htm">seal a concrete driveway</a>, 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&rsquo;s surface texture and higher density. </p></div>

Q: Will sealer waterproof my garage floor?

• <div><p>Concrete sealers will help your garage floors resist water, but they will not make the floor waterproof. You will need to purchase a specific waterproof floor paint for concrete and apply several coats over several days if you want your garage floor to be truly impermeable. While the process is similar to sealing the floors, the materials are different, and the need for multiple coats will extend the process and drying time.</p></div>
