Regardless of which granite or marble countertop sealant you choose, it’s important to thoroughly clean the entire surface prior to application of the sealant.

After cleaning the entire surface care must be taken to ensure it is completely dry before application of the sealant.

You don’t want to seal moisture into the granite, stone or marble. Remember, moisture intrusion is bad for granite, marble, stone, concrete, practically all types of rock based surfaces can be weakened by water.

It’s also very important to clean your granite or marble countertops frequently. If anything acidic is spilled or splashed on the surface and it remains in place it can slowly eat away at the clear sealing compound.

Orange juice, lemon juice, and anything with citric acid can slowly eat away at the clear protective cover. Without routine cleaning you might start to notice areas of the granite or marble becoming dull and not as shiny.

High traffic areas will be most prone to becoming dirty. The granite or marble surfaces around the sink, near the coffee pot, and stove should all be high target areas when it comes to frequent cleaning.

It’s important to understand that even the best and most highly rated granite countertop sealers are not going to work miracles. It’s imperative to clean the surface first and follow the manufacturer’s directions on the sealant container in order to achieve long-lasting results from the protective coating on your granite countertop!
