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.
3. Tenax Hydrex
This popular sealer is preferred by many for its ease of use and powerful sealing properties. You will need to clean and dry your countertops well before applying. To use this product, simply grab an old washcloth, saturate it with the Tenax sealer, and then wipe your countertop surface down completely. Allow the first coat five minutes to dry, then apply a second coat.
The second coat should be given at least 24-hours to cure before resuming with regular use. This sealer will not alter the color of your countertop or alter the appearance of the gloss.
4. Tenax Ager
Tenax Ager is another well-liked product for sealing granite countertops. This product does enhance the color of your granite and provides a wet, polished look. Make sure your countertops are clean and dry before use, then apply Ager using a clean cloth, soaked with the solution, and wiping your countertop down. Allow it to dry for at least five minutes before applying a second coat, then let the sealer cure for at least 24-hours before using your freshly treated countertops.
5. Trinova Sealer and Protectant
Trinova's Sealer is a popular household option, providing a quick and easy solution for your countertops. Wash and dry your countertops well, then just spray the solution onto your countertop in 3-foot sections and buff it in with a microfiber cloth. Wait for 1- to 2-minutes for the solution to soak into the stone, then use a fresh clean microfiber cloth to wipe the surface completely dry. This product only requires 1-hour to cure, then it's business as usual again. This product does provide a shiny, polished finish; however, it does not contain any color enhancing properties.
6. Granite Gold
Granite Gold has a well-known line of granite care products and a great reputation among its customers. This sealer is very easy to use; after cleaning and drying your surface, spray the product onto your countertop and spread it by wiping it down with a clean, dry cloth. Let the solution soak into the surface for one minute, grab a fresh, lint-free cloth and dry the countertop. Wait at least two hours before using your countertops. If you have light-colored granite, you may need to apply additional coats.
7. Weiman Granite Sealer
This Weiman sealer is highly regarded for its protective properties; however, it does apply a wet, polished look to granite, so if you desire a more matte finish, this may not be the choice for you. This sealant is easy to apply; just spray the surface until the entire area is uniformly wet and let it sit for five minutes. After the five minutes are up, wipe the countertop in a circular motion with a clean cotton towel. The application will need 4- to 6-hours to cure before you can use the countertops again.
8. Granite Gold Sealer Wipes
Granite Gold Sealer wipes are a great option if you are in a rush and require a quick and convenient method to seal your countertops. These wipes are sold as six-packs, so be sure to purchase the right amount for your project. They provide a good seal but no color enhancing or polishing properties.
Clean and dry your countertops well before applying, then use the wipes to apply the solution to your surface. Let the solution sit for one minute, then buff with a microfiber towel. The countertops will only need two hours to cure before you can use them again. While this product may not last as long as some of the typical spray sealers, it's great if you're short on time or want to avoid the mess that sprays can result in.
9. StoneTech Bulletproof Sealer
SoneTech's Bulletproof Sealer is highly reviewed and highly recommended. It requires some work to apply, but the results are well worth any hassle. You will need a paint pad, paint roller, or paintbrush, or a low-pressure sprayer to apply this product.
Apply the product liberally to your countertop surface, allowing it to sit for 10- to 15-minutes. During this waiting period, make sure to keep the surface wet, applying more sealer if any portion of the countertop appears to be drying. Once 10- to 15-minutes have passed, use a clean, dry cloth or paper towels to dry the surface.
If the countertop requires a second coat, repeat these steps within 30- to 45-minutes of the initial application. This product will require 24- to 72-hours to fully cure, but you can resume gentle use of your countertops 6- to 8-hours after application. Stonetech's Sealer does not have any color-enhancing or polishing qualities.
10. SimpleCoat Natural Sealer
SimpleCoat's Natural Sealer is quickly becoming a popular option for many reasons, it is incredibly eco-friendly, it's completely non-toxic, and it's remarkably easy to use. This product seals and protects granite very well; however, it can affect color and shine on certain surfaces.
To use this product, just apply a small amount to a clean microfiber cloth, then wipe down your countertop surface. Use another clean, dry cloth to wipe the surface again, removing any excess product, and you're done. This product does not require additional time to soak into the stone, and there's no curing time after application, which makes it perfect for anyone in a hurry.
How long does it take to seal granite?
The amount of time required to seal granite ultimately depends on the product you use. Some products can take as long as 72-hours to cure, while others have no wait time at all. Application time also depends on the surface area you need to cover, the product you are using, and the tools used for the application. 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?
There are a lot of great granite cleaners available that can be used before sealing your countertops. You will want to make sure you clean the surface well 24-hours before applying sealer and avoid using cleaners with harsh chemicals or acidic properties like lemon, vinegar, or bleach.
Method Daily Granite Cleaner
Method's granite cleaner is completely natural and contains no harsh chemicals, making it a great option for use before sealer.
Better Life Granite Cleaner
This daily cleaner from Better Life is another gentle option made from natural ingredients that would be great to use before applying sealer.
Granite Gold Sponge
A non-abrasive sponge like this one that is designed specifically for use on granite is non-scratch and can help you safely scrub away any hard water stains or stuck-on messes before applying a sealer to ensure a perfect finish.
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. The process may go quicker with some extra hands involved, but it is a perfectly reasonable task for one person to accomplish alone. Some products are easier to use than others, so make sure to choose carefully.
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. Unfortunately, these are newer technologies that have not yet been thoroughly tested and have little information available. The do-it-yourself kits designed for this purpose are complicated, costly, and are not readily available through typical outlets, only specialty shops.
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!
