How Can You Tell If Your Grout Is Sealed?

To determine if your grout is sealed, you can perform a simple water absorption test. Here’s how you can tell if your grout is sealed or not:


  1. Select an inconspicuous area: Choose a small, hidden or less noticeable section of the grout to perform the test. This ensures that any changes or potential staining will not be visible.
  2. Apply water droplets: Place a few drops of water directly onto the grout surface. Use a small dropper or a clean, damp cloth to wet the grout.
  3. Observe water absorption: Watch how the water interacts with the grout. If the water beads up and does not absorb into the grout, it indicates that the grout is sealed and providing a protective barrier. This suggests that the sealer is intact and doing its job.
  4. Check for water absorption: If the water is absorbed into the grout and darkens the color, it suggests that the grout is not adequately sealed or may require resealing. The absence of beading and quick absorption indicates that the sealer may have worn off or was not properly applied.

It’s important to note that the water absorption test should be performed on a clean and dry surface. If there are any stains or residues on the grout, it may affect the test results. Additionally, the effectiveness and lifespan of grout sealer can vary depending on the type of sealer used, application techniques, and the level of usage and exposure the grout receives.

If you determine that your grout is not adequately sealed or the sealer has worn off, you may consider resealing the grout. Properly cleaning the grout before resealing is essential to ensure the new sealer adheres properly. Follow the manufacturer’s instructions for the sealer product you choose, and apply it carefully, ensuring full coverage of the grout lines.

Regular inspection and maintenance of your grout, including periodic resealing as needed, will help prolong its lifespan and maintain its appearance and integrity.
