Is Granite Porous?

Granite is a porous stone and as such, it requires a sealer to prevent staining. However, not all granites are created equal – some are more porous than others and may require more frequent sealing. Granite sealer is often over-promoted and over-applied, so it’s important to test your surface to see if it actually needs sealer in the first place.

Supplies you will need:

  • Microfiber cloth
  • Rubber gloves
  • Granite Sealer
  • Mild Dish Soap
  • isopropyl alcohol
  • Spray bottle

How to seal granite countertops

Granite countertops are a popular choice for kitchen and bathroom counters. However, they may need to be sealed in order to prevent deterioration and staining. There are a variety of sealants that can be used, and the process is relatively simple. Sealing your counters will also help protect them from spills and general wear and tear.

STEP 1 – Do countertops need sealing

A simple test can determine if your kitchen counters need sealing? Leave a few drops of water or a wet paper towel on the counter for 10-15 minutes and see if it starts to soak in. If the water does not seep in and does not darken the granite, then you don’t need to reseal it.

However, if the water droplets sink into the stone, then it needs to be sealed as soon as possible. Another way to tell is by checking the color of your granite. If it darkens, that means that it’s losing its seal and needs to be resealed.

STEP 2: Clean the Countertop

Before you start, you must clean your countertop thoroughly. Make sure to avoid any potentially damaging chemicals, such as vinegar, lemon juice, baking soda, bleach, or harsh commercial cleansers. Instead, mix one teaspoon of dishwashing detergent and two tablespoons of isopropyl alcohol in a pint spray bottle and fill with cool water.

Let it dry and wait 12-24 hours before proceeding to the next step.

STEP 3: Test Sealant

Once you’ve acquired a new sealant, cleaned the counter. It’s time to test the new sealant.

Testing the sealant will ensure it won’t affect the finish. Apply a small amount as per the manufacturer’s directions, by spraying or pouring onto a cloth and then rubbing it evenly over the test area.

Wait for the surface to absorb the sealant and dry (refer to instructions).

If the sealant test area looks good, proceed to the Next Step. If it has discolored, wipe up any remaining sealant with a clean rag. Take a few pictures and show the results to an associate at your local hardware store for advice on a sealer that will work with your countertops.

STEP 4: Apply sealant to your Granite Countertop

There are a few key things to keep in mind when sealing your countertop:

  1. Apply a light layer of sealant over the entire surface.
  2. Make sure all parts of your counters are covered with sealer, including edges and backsplash, if applicable.
  3. Work from top to bottom using a circular motion.
  4. Follow sealer manufacturer’s recommendations for use.
  5. Wait for the countertop to absorb the sealant and dry. Usually 15 to 20 minutes. Letting the seal sit longer may discolor the stone.

STEP 5: Remove excess sealant and leave to cure

  1. Wipe off any excess sealant with a clean cloth.
  2. Let the sealant dry, this could take between 24-48 hours before using the countertop.

STEP 6: Test Seal quality

  1. Conduct a Water Drop test again.
  2. If it passes the Water Drop test, that means you have sealed your countertops successfully. Congrats!
