Sealing Marble Countertops: A Detailed Guide 

From an aesthetic point of view, marble countertops are a great addition to any home or kitchen. However, since the natural stone is porous in nature, it requires a good amount of maintenance. If you want to keep the marble shining and retain its good looks, you must invest a lot of time cleaning it. One thing that can make things easier is the sealant. 

Sealants act as a protective barrier and ensure that no liquids can seep through the material. While many homeowners are careless regarding this aspect, sealing your marble countertops from Granite au Sommet has various advantages. 

Steps to apply a seal to marble countertops

Step 1: Clean the surface. 

Buy a marble cleaner from the market that is non-abrasive in nature. Harsh chemicals can deteriorate the surface. Spray the cleaner on the surface and clean it by wiping it with a microfiber cloth. This will remove the impurities from the surface so that the dust and dirt do not interfere with the sealing process. 

Remember not to use water. Water will get absorbed in the stone, and then you will need to wait until it is dry to apply the sealing. 

Step 2: Mask off the stone. 

You do not want to get sealer on appliances and other places other than your countertop. You can use painter’s tape to avoid getting sealer on the walls, appliances, sink, and cabinets. 

Step 3: Apply sealer. 

When you have cleaned your marble countertops, and the surface has completely dried, it is time to apply sealer. Make sure you research the sealer before using it because you want the best sealer to protect your marble surface. 

Spray a generous amount of sealer to ensure it covers the entire surface. If your counter is big, working in sections would be a good idea rather than doing the entire top at once. 

Step 4: Remove excess sealer. 

After coating the countertop with enough sealer, remove the excess amount with a dry cloth. Keep rubbing the marble in a circular motion until the surface is not sticky to touch and has completely dried. Excess sealer can interfere with the aesthetic appearance of the surface, so make sure you remove it properly. 

Step 5:  You are done, but leave your countertops alone. 

After your sealer has dried, the process is pretty much completed. However, leaving your countertops alone for at least one hour or more is important. To be safe, it is better not to use the surface or put any items on it for the next 24 hours.
