How To Protect Natural Stones From Wet Conditions

To protect natural stones from wet conditions, apply a breathable, penetrating impregnating sealer that blocks liquid water while allowing trapped moisture vapor to escape.

Step-by-Step Protection GuideClean Thoroughly:

1) Wash the stone using a mild, pH-neutral stone cleaner to remove dirt, mildew, and grime. Avoid acidic cleaners like vinegar, which can etch and damage calcium-based stones like marble and limestone.

2) Dry Completely: Let the stone dry completely for at least 24 hours. Sealing a damp stone traps moisture and can cause patchy white spots or structural pitting.

3) Perform a Water Test: Drop a small amount of water onto the clean stone. If the water darkens the stone within 15 minutes, it is porous and ready for sealing.

4) Apply a Penetrating Sealer: Use a cloth, sponge, or low-pressure sprayer to apply a breathable, hydrophobic sealer designed for your specific stone type.Wipe Excess: Allow the sealer to absorb for 5 to 15 minutes, then wipe away all excess residue with a clean, dry cloth to prevent a sticky or hazy film.

5) Cure Fully: Keep the surface dry and free of foot traffic for 24 to 48 hours while the protective barrier cures.
