Checking Status Stone Sealing

If you need to know if the new stone, tile, paver or existing installation is already effectively sealed, partially sealed, not sealed or whether it can be sealed, continue reading!
“Determining if a stone is sealed is an important question which must be answered prior to considering the application of a new sealer treatment. Realising if an unsealed stone surface will be able to accept a sealer is also critical in determining how to move forward. There is a simple “Water Test” that will help you determine, not only if the tile is sealed or not, but give you a guide as to what sealer should be used. 

How to check whether a new stone, tile or paver is correctly sealed:

  1. Apply water to a few different areas of the stone and/or grout.
  2. Make each application of water approximately 25mm in diameter
  3. Measure the approximate size of the circle of water, without disturbing the water, and make a notation of position and size
  4. Place a drinking glass over the water to protect it from evaporation and let it sit undisturbed for 20 minutes
  5. After 20 minutes, remove the glass and observe the results

How these results determine the quality of your stone sealing:
