Why you should seal your granite countertop
You need to preserve its original
Over time, it may turn dull, especially for darker choices of color. The seal
would prevent oil, liquid, and other contaminants from leaving mineral deposits as it
makes it look cloudy and a little overcast.
You need to prevent stains.
To make its stain resistance stronger, granite must be sealed properly. This
will help the surface to not absorb any liquid that may cause stains.
You still need to prevent etching.
Though granite is known to withstand acids and bases, granite
countertop sealing serves as a precautionary measurement. Acid spills when
left long enough, could cause discoloration and damage some of the minerals.
You need to lessen the cleaning effort.
Having your granite sealed will lessen the cleaning time and effort. It would
be easier as it only needs to be wiped without any heavy scrubbing needed.
You need to prevent bacteria from growing.
Since granite is porous, it may harbor bacteria. And if not sealed, cuts and
cracks might pop out from time to time - giving bacteria places to penetrate and live.
How often should you reseal your granite counter?
Think of your granite countertop as a permanent investment where regular
maintenance is required to keep its original attractive state. Sealing depends on the
frequency of your cooking. It is recommended to have it sealed at least once a year. But
if you’re a regular kitchen user who cooks all day and uses the countertops regularly,
then you may reseal it twice a year. Thanks to recent advancements, there are
long-lasting sealers that reduce the frequency of your application.
How to know if it's time to seal?
You can test your granite counter by leaving a few drops of water on the
surface. Observe what happens over a few minutes, like five or so. If the droplets
remained on the surface counter, you’re good to go. But if the droplets were absorbed
into the granite, then you need to reseal your kitchen counter.
