How To Seal Your Granite Countertops

If you had new granite countertops installed, the first thing you need to do is ensured that they are sealed. Sealing your granite countertops is the only way you’ll know they will shine like new and have a long life span. Homeowners across the country will consider the different maintenance needs when considering what countertop material to install. Granite doesn’t require major amounts of maintenance and can add value and beauty to your home. 

Granite countertops are made of different natural materials and quartzite. The different styles that granite comes in make it a perfect choice for all sorts of different environments. Granite is also very resistant to stains and other common damages. Ensuring that your granite countertops look good at all times can take more than just the occasional wipe-down. That is why sealing your granite countertops is so important.

Is Granite a Porous Material?

Many homeowners wonder if granite is considered a porous material. Granite is a porous material which is why you need to ensure they are sealed correctly. Not sealing your granite means liquids will penetrate your countertops and leave large stains and discolorations. The best way to know if you need to reseal your granite countertops is by doing a water test. 


The Granite Countertop Water Test

If you are wondering if it’s time to reseal your granite countertops, then perform this easy test to find out. Follow these steps:

  • Pour ¼ cup of water on our granite countertops
  • Time how long it takes for the water to be absorbed into the granite
  • If the water is not absorbed and remains on the countertop, then you don’t need to reseal
  • If the water is gone and there is now a dark spot instead, this means you need to reseal your countertops. 


Granite Water Absorption

  • Water absorbed instantly means you need to apply a few layers of sealant
  • 4 to 5 minutes means you’ll need multiple layers of sealant and you should reapply every 3 to 5 years
  • 10 minutes means you’ll only need one to two layers of sealant and should reapply after many years have passed.
  • 30 minutes or more means you don’t need to seal and won’t need to for some time. 


Sealing Your Granite Countertops

Once you’ve performed the water test, now it’s time to apply sealer. No sealer will make your granite 100% safe from liquids, but they give you plenty of time to wipe the liquid away before it’s too late. 


  • Step 1: Find a quality granite sealer. Safe and proven options include MORE surface care and Stone + Quartz cleaner. 
  • Step 2: Carefully read through the sealer instructions. Each sealer will most likely have different steps 
  • Step 3: Make sure your granite countertops are completely cleaned and wiped down. 
  • Step 4: Apply the sealer evenly across the countertops
  • Step 5: Wipe off the sealer after the recommended amount of time. You may want to apply one or more layers of sealant depending on what the water test produced.
