Natural stone countertops such as marble and granite make gorgeous additions to any kitchen. They certainly elevate the elegance of your home and will make you and your guests want to spend more time here. However, it should be said that both marble and granite countertops require some TLC in order to maintain their strength and beauty for decades.

Whether you use marble and granite countertops in your kitchen, or other parts of your home such as bar, laundry, office, or bathroom, they will last you a long time as long as you invest some time into maintenance. That’s because the nature of these stones, and the way they tend to be used in homes, makes them vulnerable to stains caused by exposure to food, water, drinks, and other environmental factors.

They are porous, which means that they have microscopic voids in them from where oil, water, food, and other sources of stains can get stuck in – leaving you with unsightly marks on your once-beautiful countertop. The simple, fuss-free use of a marble or granite sealer already prevents these headaches because they make the stone impenetrable to liquids. 

Meet Dupont Stonetech Bulletproof Sealer, your new best friend. This highly advanced formula was designed to offer maximum protection for marble and granite, even for tough oil and water-based stains. 

This sealer is so popular and for good reason; it’s clear that if you have a granite or marble countertop in any part of your home, this is the sealer you should be using. Aside from protecting from a huge majority of common and not so common stains, Dupont Stonetech Bulletproof Stone Sealer also provides state-of-the-art penetrating microbond protection. 

Dupont Stonetech Bulletproof Sealer can be used on several substrates including honed and textured marble, granite, travertine, limestone, bluestone, Saltillo, quartzite, and flagstone.

Any homeowner who has used these stones will tell you that yes they are beautiful, but they aren’t cheap. That’s why maintenance is crucial.

Dupont is a trusted consumer goods brand that has been around for over 200 years. They are known for applying scientific principles to create household items that increase our quality of life, and their sealers are no different.

Dupont Stonetech Bulletproof Sealer is heavy-duty, and that already makes it a notch above all its competitors. It’s also really easy to apply – all you need to do is give your countertop a good cleaning, apply the sealer, wait for it to activate, and then wipe off the excess. 

What’s more, you can have peace of mind knowing that this sealer won’t change the look of your natural stone investments. It was formulated to protect while enhancing your stone’s beauty.


Dupont Stonetech Bulletproof Sealer is not only effective, it’s versatile and extremely useful too. Here are the main benefits of using this sealer.

We know how expensive your marble, granite, and natural stone investments can cost, so you shouldn’t be waiting too long before sealing it. These will only be permanent investments if you invest in their maintenance too.

How often you’d need to reapply sealant will depend on a variety of factors, though it’s recommended to seal granite countertops at least once a year.

How Much Granite and Marble It Can Seal

One quart of Dupont Stonetech Bulletproof Sealer can seal up to 225 square feet for one application. On the other hand, a gallon can seal 900 square feet with one application. 

Isn’t Dupont Stonetech Bulletproof Stone Sealer so cost-effective?

Keep in mind that the amount of surface it can seal will depend on the exact type of stone you are using, and its porosity.
