Set In Stone: How To Seal Your Marble Countertops

Marble is a type of stone that has been around for generations. Ancient Greeks and Romans used pure white marble to create beautiful sculptures. Now, people use marble for their countertops, backsplash, and even floors. Unlike granite, marble is extremely porous, which causes it to absorb stains and other impurities easily. To keep your marble countertops clean, you need to seal them every few months. Here is how to seal your marble countertops properly.

Materials needed:

  • Bucket or bowl
  • Foam brush
  • Microfiber rags
  • Marble cleaner
  • Marble sealer

Cleaning

To clean your marble countertops, all you need to do is use the marble cleaner. Spray the marble with the cleaner and wipe the countertop until it's completely dry. If you have any impurities on your countertops when you try to seal them, it could interfere with the sealing process.

Sealing

Once your countertops are completely clean, you can seal the marble. The first thing you want to do is open up some windows and turn on any ceiling fans in your home. Marble sealer has a strong and harsh smell, so you don't want to seal your countertops in a closed up home. Pour the sealer into a small bucket or bowl. It just has to be big enough to dip your foam brush into. Dip your brush into the sealer and brush it onto your countertops like you are painting them. Have your strokes slightly overlap each other to make sure that you don't miss any spots.

Buffing

Once you have completely covered the marble with sealer, you need to let it sit for about 10 minutes. Once the 10 minutes is over, take another microfiber rag and wipe away all of the excess sealer that hasn't dried. You want to rub it in a circular motion like you are buffing a car. If the counters are a little sticky when you touch them, keep buffing until they are dry and smooth. Any sealer that is left on the stone can make the stone hazy after it sits for a while.

Tips

  • When your marble countertops are properly sealed, they will mimic the properties of a waxed car. When your spill liquid on sealed countertops, the liquid will bead. If the liquid isn't beading, you know it's time to seal your countertops.
  • Etching is a huge problem with marble countertops. Chemicals and acids will etch the marble, meaning dull spots form on the stone. Sealing your countertops will prevent the etching from occurring.

Marble countertops are a beautiful addition to any home. You just need to make sure that you provide the proper maintenance so they stay beautiful. Make sure you seal your countertops as needed to keep stains and etching away.
