This guide will walk you through the sealing process and maintenance tips for your beautiful granite surfaces.

How to Seal Granite Countertops (and When to Reseal Them)

Understanding the Importance of Sealing Granite

Granite is a porous natural stone, which means it can absorb liquids and stains if not properly sealed. Sealing helps protect the surface from damage while maintaining its beauty. Regular maintenance, including sealing, can extend the life of your countertops and enhance their appearance.

How to Seal Granite Countertops

Step 1: Gather the Necessary Supplies

Before you begin the sealing process, gather all of the necessary supplies:

  • Granite cleaner
  • Soft cloths
  • Granite sealer
  • Cotton swabs (optional for tight areas)

Step 2: Clean Your Granite Surface

Before applying any sealer, it is crucial to clean your granite countertop thoroughly. Use a granite cleaner and a soft cloth to remove any debris, grease, or stains. Allow the surface to dry completely before proceeding to the next step.

Tip: Avoid acidic cleaners

Acidic substances can damage the surface of your granite. Always choose pH-neutral cleaners specifically designed for granite care.

Step 3: Apply the Sealer

Once your countertop is clean and dry, it’s time to apply the sealer. Follow these steps for the best results:

  • Apply the sealer evenly across the countertop using a soft cloth or a foam applicator.
  • Make sure to cover the entire surface, including edges and seams.
  • Allow the sealer to penetrate the granite for the time specified on the product instructions.

Step 4: Wipe Off Excess Sealer

After allowing the sealer to penetrate, use a clean cloth to wipe off any excess. Leaving excess sealer on the surface can result in a sticky residue that may attract dirt.

Step 5: Cure the Sealer

Follow the manufacturer’s instructions regarding how long to let the sealer cure. It’s usually best to avoid using the countertop for at least 24 hours after sealing.

When to Reseal Granite Countertops

Even with regular sealing, your granite countertops will need maintenance over time. Here are key indicators that it’s time to reseal:

Visual Inspection

Look for signs of wear or dullness. If your countertops appear less shiny or show signs of staining, it may be time to reseal.

Water Test

Another effective method to determine if it’s time to reseal is to perform a water test. Pour a small amount of water on the countertop:

  • If it beads up, your granite is still sealed.
  • If the water soaks in, it’s time to reseal.

How often should you reseal?

Generally, granite countertops should be resealed every 1-3 years, depending on usage and exposure to contaminants. Regular maintenance will keep your granite looking its best.

Granite Care Guide

Proper care and routine maintenance can significantly extend the life of your granite countertops. Here are essential tips:

Daily Cleaning

Wipe your granite countertops daily with a soft cloth and a mild, pH-neutral cleaner. Avoid using sponges or abrasive materials that could scratch the surface.

Deal with Spills Immediately

Promptly clean up spills to prevent staining. Use a soft cloth or paper towel to blot, rather than scrub, the area where the spill occurred.

Protective Mats

Consider using mats or trivets under hot pots or pans. This can help prevent heat damage, which may compromise the surface of the granite.
