Before sealing your marble countertop, it should be clean. Use the dishwashing soap and water mixture to wash the entire surface, rinse it, and dry it well. Make sure to take all of the items off your countertop so the entire surface is clear. If there are any areas of the counter that are coated with residue from cooking grease, cleansers, or other substances, scrape it off before sealing the countertop. Use a plastic scraper or knife to carefully remove it. You can also use a single-edged razor to remove the residue, but be very careful because you can easily cut yourself. Hold it at angle as you move it over the marble. With a countertop that’s already been sealed, you should strip off the old sealer before applying a new coat. Wet a clean cloth with acetone and smooth it over the marble. Next, dampen another clean cloth with warm water to remove any residue. Dry the counter with a microfiber towel. Don’t allow the countertop to air dry; wipe it down to dry it. When the countertop is clean and dry, read the sealer’s instructions and apply it as directed. Most sealers require pouring the product onto the counter and using a white cloth to spread it evenly across the surface. You usually must also allow the sealer to soak in for a specified amount of time, which is just 3 to 4 minutes. Always apply the sealer exactly as directed to on its packaging. Some sealers may require alternative application methods. After you’ve allowed the sealer to soak in for the proper amount of time, you must remove any excess product that hasn’t absorbed. Use a clean dry cloth to wipe it away. Some sealers may require a second coat. Read the instructions to determine if it’s necessary, as well as the proper procedure for applying it. To keep your countertop stain-free, you should reseal the marble every three to six months.
