Why Seal Granite Countertops?

Granite is a naturally occurring stone that is made into a countertop but it requires proper care, maintenance, and regular sealants. Sealing your granite is important for it to shine like new and have a long-lasting life. You are going to lose its beauty if you do not apply the sealants. Read below why?

Durable But Porous

Granite is a really hard and durable countertop material but is porous. Its naturally occurring quality makes it susceptible to absorbing water, liquid spills, and other things. So, if your granite countertop is not sealed and you spill something then it will get stained and marked due to the spill. You wouldn’t want that to happen and keep it like new. Now, usually, newly installed granite countertops are sealed by the installation company. But it needs resealing every year or so.

Checking The Condition Of Your Granite Kitchen Countertop

Once your granite is sealed and then you are free. No. You need to reseal your granite countertops again and again. Usually, you will need sealants on an annual basis. But if your granite countertop is used more than usual then you will need to seal it every 6 months and if it is very well maintained then you can even do it every 1 and a half years.

But how would you know when is it time to get your granite resealed? Simple, perform the water test. Spill some water on your countertop and if it forms into little beads of water then you do not need to seal it but if the water seeps in the countertop and firms a stain then it is time to apply sealants. Make sure to perform this test on a small corner of your kitchen so the mark is unnoticeable.
