Any granite surface, even when of the best possible quality, can easily lose its aesthetic charm if you don’t make an effort to protect it using a granite sealer. Without this simple but important compound, oils and stains can seep into the granite and ruin its look. Granite has tiny holes that have to be sealed with a compound that does not ruin the stone or its appearance.
Otherwise, stains and other substances can fill up this space and ruin the granite entirely. Ideally, your granite surfaces should be sealed after they have been cleaned and polished; and there are plenty of compounds that are made specifically for this purpose.
Poor quality sealing products can lead to the granite surface getting ruined several years before its time. With that in mind, here are the best granite sealers at the moment.

How to Seal a Granite Counter
There’s no doubt about it: granite is a remarkable surface. It’s beautiful, durable and if properly taken care of, will last for a very long time. Which brings me to my point. If you have a granite surface, it’s absolutely vital that you take proper care of it. And that means using a granite sealer on it.
When a granite counter has been properly sealed, it will be more stain resistant, and it will also resist bacteria buildup. However, it should be kept in mind that the surface it’s applied to won’t be invulnerable. It will still be possible for it to be stained or for it to harbor bacteria if it isn’t properly cleaned. All the sealant will do is give you a little bit of extra protection against these things from happening.
After you’ve finished picking the best granite sealer possible, it’s time to take a few moments to learn how the product is applied. The following tips are a general overview of how this product is applied and will give you an idea of the process. However, it should be stated that it’s only a generalization and you should always follow the instructions listed on the product you use.
Step One: Choose a Product
While the list of our top ten granite sealers is a good place to start when you’re looking for a good sealer for your granite, it’s probably a good idea to learn the general principles behind what really makes a great sealer.
That way you can determine for yourself if a particular sealer is something that you want to purchase. The first guideline you should keep in mind is that you should only buy a sealer that’s designed for natural stone. And if it’s possible, not only a product made specifically for natural stone but one that’s also specifically designed to be used on granite.
The next thing to keep in mind is that you are probably going to want to choose a carbon resin-based sealer. While this type of sealer is generally more expensive than other sealers, it will provide years of protection to the stone surface. If carbon resin-based sealers aren’t available, however, then try to use a silane-based sealer. They aren’t as effective at sealing than carbon resin based formulas, but they are generally the next best option available.
Step Two: Study Your Instructions
I’m probably being a little redundant mentioning this fact, but I do feel that it bears repeating. Always thoroughly read the manufacturer’s instructions on your product’s label.
If there are any contradictions between the instructions in this guide and your product’s instructions, then your product’s instructions should be followed instead of these guidelines.
Step Three: Clean Your Granite
The next thing you should do is clean your granite thoroughly. While this can certainly be done with just plain water and dish soap, it’s preferable to use a stone cleaner and a dry towel for best results. There are a number of great stone cleaning products from companies such as Weiman, Black Diamond, and TriNova, so choose a cleaner that you like.
If you use a product that degreases the stone as it cleans, then be sure to do a final wipe with alcohol. After the product has been cleaned, you should probably wait for at least 24-hours to give the granite surface a chance to dry. Once that period has elapsed, you can continue with sealing it.
Step Four: Take Safety Precautions
Granite sealers can produce harmful vapors while they’re being applied, so it’s important to take the proper precautions when using this product. This means wearing gloves and a ventilator. It also means opening a window while you use the product. Once you’ve taken these precautions, you can then move on to actually sealing the granite.
Step Five: Do a Sample Test
Not every sealer is compatible with every stone surface, so it’s important to do a sample test before applying the product to a large portion of your granite counter. Apply some of the sealant on a small portion of the counter and see what it does. If it becomes cloudy or discolors the granite, then don’t use the product and instead find something that’s more compatible with your counters.
Step Six: Apply the Sealant
Now that you’re prepared and have determined that your product is safe to use on your granite counter, it’s time to actually apply the sealant. Wet a cloth with the product and evenly distribute it all over the counter. Make sure that the granite is damp, but not soaked down, and that the product has been evenly distributed over its entire surface.
Step Seven: Allow it to Sit
Once you’ve applied the product evenly to your granite, it’s important to sit so that it can soak into the stone. You should follow the instructions on your product’s label and allow it to sit on the granite for the amount of time it specifies. This is usually about 15 to 20-minutes.
Step Eight: Apply a Second Coat
Some products suggest adding a second coat to the granite. If yours is such a product, then apply the second coat on the surface only after the original coat is completely dry. Make sure this coat, like the first coat, is also evenly distributed. Allow this coat to dry for the recommended amount of time.
Step Nine: Cleanup
Make sure that you clean up any extra sealer off of the granite surface. If too much sealer has been applied to the granite, then it can leave an unattractive cloudiness on its surface, so be sure it’s cleaned up.
Step Ten: Wait
Now comes the hardest part of the process: waiting. After the product has been applied, it’s important that you don’t disturb it for at least 24 to 48-hours. Sure, sealers dry to the touch within 1 to 2-hours, but for best results, you should not wash the surface of the counter for a day or two to allow the sealant to properly cure. Once this period has passed, you can then use the counter as you normally would.
