Importance of Sealed Stone by LATICRETEThe Importance of Sealed Stone Determining if a stone is sealed is an important question that 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 important in determining how to move forward. There is a very simple and inexpensive test to determine if the stone, Saltillo tile, or cement-based grout is currently sealed, or if it even requires a sealer. Water Test A quick and easy test is performed with water and can provide valuable information about the current state of the stone or grout surface:
After 20 minutes remove the glass(es) and observe the results; No change - If the water appears the same as when it was applied and the water measures the same diameter, then a sealer is already present or the stone is very dense and does not need a sealer. Slight change - If the water is still present in a bead but appears to be absorbing into the surface then a sealer may already be present but requires resealing. Or, the stone is not sealed and is dense enough to allow for the slow absorption of water. Complete change - If the water is completely absorbed into the surface and the spot appears to have grown in size, then the stone is not sealed and the use of a high-quality sealer (e.g. STONETECH® BulletProof® Sealer, STONETECH Heavy Duty Sealer, STONETECH Impregnator Pro® Sealer, etc) is strongly recommended.
