Granite surfaces undoubtedly make for good investments. Besides being naturally beautiful, granite is known to withstand years of use and provides protection against stains and other hazards, particularly liquids. But as you may have found out, this type of stone is not perfect, and under daily use, some moisture will occasionally seep through your countertop or flooring, sometimes leaving behind very unsightly marks.
For this reason, granite countertops should always be sealed. The right sealer will not only make the surface impenetrable but also improve its aesthetic appeal and shine. Unfortunately, there’s not a single sealer that’s best for everyone. The available options differ in terms of formulation, durability, working mechanism, and cost.
In keeping true to our word to provide up-to-date information about modern go-to products, we scoured the market and did some research on the best granite sealers. At the end, we settled on three brands. Here’s what you need to know:
This is a water-based sealer that costs about $17.77 as of this writing.
There are simply very few sealers that can match Granite Gold 24-oz in terms of ease of use, efficiency, and effectiveness. Its manufacturer – Granite Gold – has been in the stone-care industry for over 50 years, a period during which the company has brought together experts from around the globe to assemble quality sealers for quality countertops.
It works by chemically combining with granite to form a super hard coating that keeps out moisture, stains, and liquid spills. The bottle comes with a fitted easy-to-squeeze nozzle that simplifies the spraying process.
If you regularly place fresh farm produce on your countertop, it’s no secret that soil and sand particles will keep on being unwelcome guests. But with this sealer, you can ensure that such particles do not attach to the surface.
Many people love this product in part because it is non-toxic, which means it does not endanger your health even when contact is frequent. In particular, all the ingredients are non-acidic to prevent corrosion or skin damage. In fact, it’s safe for use around the kitchen where there are food materials, cutlery, and other culinary items.
A possible downside might be the fact that this sealer is not permanent. You must regularly perform a water test to check its integrity. To do that, you need to pour two to three beads of water on the surface in several locations and wait for about 20 minutes. If dark ring forms at any of the watery spots, you might want to reseal.
Granite & Stone Sealer
For resilience against a range of destructive substances such as stains and oil spills, you might want to try the Weiman Granite & Stone Sealer.
This water-based solution is formulated to strengthen the bonds between granite particles and form an invisible protective layer that sits on top of the natural stone to prevent water or oil from penetrating the surface. It helps to extend the life of granite countertops and keeps them looking new throughout.
Part of its popularity has much to do with its versatility since it fairs well on a range of surfaces including kitchen, bathroom, and outdoor areas. In addition to granite, it works well on Marble, Limestone, Slate, Sandstone, Onyx, and Quartz. This sealant also works amazingly well on alkaline surfaces and a variety of substrates.
The product offers more than just protection. You can use it as a cleaning agent to restore the shine and elegance of granite surfaces. Unlike other brands, it has low VOC and is, therefore, ready to use without prior heating. Furthermore, it won’t crack or freeze when used outdoors.
What really sets this sealant apart is its durability, and a single coating can last up to 12 months. Resealing is required only when water droplets fail to bead up on the surface.
Selling at slightly over $29 as of this writing, the Weiman Granite & Stone Sealer might be a bit more expensive compared to other brands, but it gives good value for money.
BulletProof Sealer is by far the most chemically advanced sealer in the market. It features an advanced microbond that combines with stone to create an impenetrable wall for effective protection against oils and stains.
Although it can be used on granite, it’s also effective on marble, travertine, bluestone, and a range of other natural stones, making it a versatile sealer among men and women with a knack for variety. In addition, it can be used in both interior and exterior applications. It improves the texture and feel of surfaces making cleaning easy and enjoyable.
If you want a sealer that cures almost instantly, look no further. With surface temperature of 10-27 degrees Celsius and good ventilation, the treated surface takes less than an hour to dry up. While most sealers need resealing within months of application, this brand scores highest in terms of durability. A good coating can last up to 5 years. All you need to do is to ensure the surface is clean and wax-free prior to application.
As if that’s not good enough, a gallon will cover up to 900 sq. ft. giving you the best value for money. The sealer also does not interfere with the natural color of granite or stone. Instead, the two bond and blend well to create an even more attractive surface.
If the can is opened, the sealer’s effectiveness reduces quite fast. For this reason, it might be advisable to apply as much of it as possible immediately after purchase, when its quality is highest.
Granite Gold 24-oz might be the ideal choice for individuals looking for an effective sealer on a budget. It’s also loved by people with skin allergies because of its non-toxic and non-acidic nature. If you have a vegetable garden in your backyard, using this sealer will prevent soil build-up on your countertop.
If you’re looking for a versatile sealant to use on multiple surfaces, the Weiman Granite & Stone Sealer could be your best bet. Besides being a great protectant, it helps to keep surfaces clean and shiny. It’s also recommended for buyers with a modest budget.
The StoneTech BulletProof Sealer might be the best choice if you have durability and strength in mind. Thanks to an advanced formula, your granite countertop can retain its glamor and shine for years and years.
