How can I tell when it’s time to seal my granite countertop?
To figure out when your granite countertop should be resealed, it’s best to test the granite first to see if resealing is absolutely necessary –
Water Test – Sprinkle three drops of water on the granite. If the granite darkens and absorbs the water within four minutes or less, the counters need to be resealed. This test should be done every few months to truly see how often you should reseal your countertops.
Tip: Try the water test again after the sealer has been applied. This will help determine if the surface has been effectively sealed or if a second or third coat is needed.
