<h4 class="dechead">On One Hand: Reseal Granite Once Every Six Months to Two Years
Granite countertops are fairly porous and stain easily. In order to maintain a granite countertop's shine and durability, experts recommend resealing a granite countertop every six months to two years depending on how frequently the kitchen is used. Different types of granite require different frequencies of sealing, so it is best to check with a manufacturer to see if yours need to be resealed closer to every six months or every couple of years.
On the Other: Some Granite Doesn't Require Resealing
In order to find out if your granite countertops need resealing, you can perform a water test. Simply place a few drops of water on your granite countertops and if the water absorbs into the countertop, it needs to be resealed. If the water beads up on top of the countertop, it doesn't need to be resealed.
Bottom Line
Most granite countertops need to be resealed at least once every couple of years in order for them to stay stain-resistant, keep their original color and sheen, and resist damage.
