Best Sealers For Granite Countertops

Granite countertops undergo wear and tear from daily use, especially when installed in the kitchen. For new countertops, you won't have to worry about sealing just yet. Daily cleaning will keep your granite countertops in good working order with a nice finish. But, over time, your counters will need to be resealed either annually or every 3- to 5-years. Sealing prevents porous granite from soaking up spills that can stain to keep your granite's color and finish long-lasting.

1. Supreme Surface

This product has great reviews, and it's very easy to use, but it does require more effort than some of the other options. The kit includes everything you need to clean and reseal the surface of your granite countertops, including a daily use granite cleaner spray, a treatment solution containing a polish and sealant, as well as a microfiber cleaning cloth.

The first step is to clean the countertop really well with the daily cleaner and dry the surface. Next, you apply the polish and sealer, then buff it into the surface with the microfiber cloth. This process will initially need to be repeated for 10-14 days; after that, you will only need to apply it once a week to maintain the protective coating.

2. Black Diamond

The Black Diamond sealer and color enhancer is runner-up. This product has great reviews, and it's pretty simple to apply. First, clean your countertop thoroughly, then allow the surface to dry completely. Next, apply the sealer to the surface with a paintbrush, paint roller, or a low-pressure sprayer. You will need to keep the countertop surface moist with this product for at least ten minutes, reapplying if the surface begins to appear dry. Once the ten minutes are up, wipe the countertops dry with a lint-free towel.

As its name suggests, this product will enhance your countertop's color, making the granite more vivid. If you want to avoid altering the countertop's current color, you may want to consider a different product.

The time required for the application can vary between 15-minutes to several hours, depending on various factors.

What do you clean granite with before sealing?

How often should I seal my granite countertops?

This varies depending on the color of your countertops and the amount of use they experience. If you use your countertops heavily, or if they are made from light-colored stone, you may have to seal your countertop once every 3- to 6-months. If your countertops get little use or are very dark, you may only have to seal them once a year. Another consideration is the type of sealer used; check the packaging to see how often the manufacturer recommends re-applying.

Can you seal granite yourself?

Yes! There are a lot of great sealers that are very simple to use for the average homeowner.

Can granite be sealed permanently? 

A few companies manufacture granite countertops with a permanent factory seal; there are other companies that offer kits that can permanently seal your granite countertops.

The do-it-yourself kits designed for this purpose are complicated, costly, and are not readily available through typical outlets, only specialty shops.

In Conclusion

There are many options available for great granite sealers. The one you chose will ultimately depend on the finish you desire, the amount of time allotted for the project, and the ease of application. With this comprehensive list, you can find the perfect option for your situation. Enjoy your beautiful, freshly sealed countertops!
