How to Seal your Granite or Marble Countertops
Sealing your granite countertops is simple. You can do it in a quick 20 minute routine.
Clean all of your countertops with a clean cloth. Obviously, all the daily used objects should be removed from your countertops before you start cleaning.
Feel the countertops with your hand to feel if any food or debris is still present on the countertop.
If you find some debris, you can clean with a mild soap and warm water and then wipe off again with a clean, dry cloth.
Wear kitchen gloves and spray the stone sealer on the surface of the granite.
Be generous while spraying and make sure you have a good layer of liquid on the countertops. This is to make sure there is enough liquid to penetrate the naturally occurring pores in the granite. This is important.
Wait about 15 minutes and then wipe off the excess liquid from the countertops with a clean, dry cloth.
Depending on the type of stone, you may find some hazy spots after you wipe off the excess liquid.
If this happens pour a very small amount of sealant on a clean cloth and wipe off the hazy spots. They will disappear.
Now, your countertops are sealed. It takes about 24 hours for the sealer to take full effect. In order to have the maximum stain repellent properties you may repeat this process one more time after a gap of 2 to 3 days.
A little note here about stone sealers. Stone sealer is a misnomer because the sealer is actually an ‘ impregnator ‘ that penetrates the pores of the stone surface rather than sealing the pores. In strict sense stone sealers are stain repellents rather than sealers.
