What Is the Best Granite Sealer?

When you have granite countertops—or any porous, natural stone, for that matter—keeping them looking their best is always a goal. While stone countertops are known for their durability, part of that durability stems from providing a waterproof sealant to protect the beautiful stone underneath. It can be a little challenging to determine which sealers are the best for the countertops that you spent your hard-earned money on.

Why You Should Seal Granite

Granite is a porous stone, which means that water or other liquids can seep in and cause damage. When you cover the stone with a sealant, you prevent any liquids from getting down into the stone where they can cause etching or staining. This is so important as grease, wine, oils, acids, and other liquids can cause permanent damage and stains that can’t be removed.

Once you have sealed your granite, liquids and oils will bead on the surface instead of seeping into the stone. A sealer also prevents damage from chemicals in cleaners that aren’t meant for granite and natural stone surfaces.

What You Shouldn’t Use to Seal Granite

Not every sealant is appropriate for use on granite. In fact, there are special natural stone sealers made just for this purpose. Don’t use outdoor sealing products or those made for wood, teeth, automobiles, or really anything other than stone. You could cause permanent damage to the stone or make the surface dangerous for food preparation or even touching.

How to Seal Granite Countertops

Sealing granite countertops doesn’t have to be difficult. Follow these easy steps to protect your granite:

  1. Remove any debris from the area and thoroughly clean the countertop surface.
  2. Once the surface has dried, shake your can of Rock Doctor Granite and Stone Sealer well.
  3. Holding the can six to eight inches from the surface of the stone, spray the sealer onto the desired area.
  4. Let the sealer sit for two to three minutes.
  5. Wipe the sealer off with a dry cotton cloth or paper towel.
  6. Let dry for at least 30 minutes.

Unlike many other sealers, ours doesn’t require you to keep your countertops clear for days after application while the sealer sets.

We do recommend that you reseal your granite surfaces every six to twelve months, depending on how often you use the surface.
