Sealing Marble Countertops: A Step-by-Step Guide



Marble countertops are a great addition to any kitchen or bathroom in terms of aesthetics and design. On the other hand, marble is a soft, porous stone that needs regular care to keep it in peak condition. Sealing your marble countertops yearly or biannually is the most acceptable maintenance practice apart from regular washing and avoiding acidic or abrasive chemicals.


Sealing helps preserve the marble by filling its pores with sealer instead of whatever liquid ends up on your counters. It also serves to establish a protective barrier over the marble.


We’ll walk you through the process of sealing your marble countertops in the following paragraphs. Follow along with the written instructions below. Sealing natural stone worktops, such as marble, is an easy DIY project, but if you don’t have the time or experience apprehension, you can always contact a specialist. Whoever likely sold you the stone can also help you care for it.


How to Protect Marble from Stains


Performing the Waterdrop Test is a helpful pre-sealing step that may help you identify whether your existing seal has worn away. Water droplets are sprinkled on the counter to see how the old seal performs in this test. Your seal stays intact even if the beads fall off. If they evaporate, it’s time to reseal your marble surfaces since your seal is likely gone.


The first step 


Remove any clutter from your countertops. Then, using a moist towel, wipe the countertops clean of dust or other debris. Using a marble or granite cleaning solution made particularly for cleaning natural stone is recommended if you want to take this step to the next level.


The second step


It’s time to seal your marble countertops now that they’ve dried. Use a professional and qualitative marble countertop sealer to ensure it will stay in place for a long time.


Be sure to cover the dry marble countertops’ whole surface with a thick sealant coating. The size of your kitchen may necessitate working in portions so that you don’t become overwhelmed or lose sight of which places you’ve previously sealed.


The Third Step


A 15-minute drying period is necessary after applying the sealer to ensure that the sealer is relatively dry before proceeding. As long as it doesn’t completely dry on the surface, you’re looking for a good seal. It’s vital to keep an eye on the sealer as it dries and settles since this might leave a haze.


If, after 15 minutes, the sealer has not penetrated the pores and crevices of the marble, reapply the sealer and repeat the process. The next step is to remove any residual sealant from the surface using a clean, dry cloth. To clean it up, reapply the sealer and wait a few minutes before wiping it up with a dry cloth or paper towel. That should keep the seal clean.


The last step


Remember to leave your countertops alone for at least an hour after cleaning them. Keep your counters clear for the following 24 hours as a general rule of thumb. This waiting may not always be required, but it will ensure that no one, even you, can compromise the yearly seal.
