Buying Guide


Types of Granite Sealers

Granite is a big investment, so homeowners want to keep it in tip-top shape. That means keeping it clean and regularly maintaining it with a sealer. Not only should granite be sealed, but it also must be cleaned. A wide variety of products are available for cleaning granite surfaces.

A plethora of granite care products are available in today’s market. Many of those products serve the same purpose, but they do so with different methods. The three most popular sealants are penetrating, enhancing, and topical sealers.

Penetrating Sealers

Penetrating, or impregnating, sealers protect granite surfaces by plugging the porous surface with resins. Solvent- and water-based penetrating sealers are available, both of which help the resins soak into the pores. Once the water or solvent dries, it leaves the resins behind to protect the surface from stains.

Penetrating sealers do most of their work from under the surface, so they don’t offer much protection against scratches and etching from acidic substances. Also, these sealers offer stain-resistance, not stain-proofing.

Enhancing Sealers

Older granite surfaces may need an enhancing sealer. They enrich the look of the countertop by soaking deeply into the surface to create a shiny, wet look. They often can reinvigorate older, dull surfaces.

While the process is complicated to explain, the idea is that an enhancer helps the stone do a better job of reflecting light, creating a shiny, yet darker, surface. Most enhancing compounds also provide a bit of sealant protection, much like an impregnating or penetrating sealer.

Topical Sealers

Topical sealers create a layer of protection on the outermost layer of the stone. They create a shiny, glossy finish, and they protect the surface from scratches, dull spots, and other undesirable marks. They work well on flooring, mantels, and other rougher stone surfaces. The rugged texture of these materials gives these types of sealers a “tooth” onto which they can grip to create long-lasting protection.

Topical sealers aren’t always ideal for countertops. Some don’t apply particularly well to smooth surfaces, and they can also block moisture from escaping the stone, causing cracks when the moisture tries to escape. Use a product meant specifically for countertops.

What to Consider When Choosing the Best Granite Sealer

Besides the different types of granite sealers, there are other features and attributes to look for in a sealer. This section outlines the most important things to keep in mind while shopping for the best granite sealers for your stone surfaces.

Form

Granite sealers come in a few different forms, including sprays, liquids, waxes, and polishing compounds. Consider each type of product’s capabilities to determine which may work best for your needs.

Liquids, whether in a spray bottle or jug, have the best chance of penetrating into the granite, enhancing and protecting the granite from within. These sprays also come in aerosol cans, allowing fast coverage.

Polishing compounds, which are usually thicker, take a bit of elbow grease to apply. Much like waxing the surface of a car, the compound must be worked into the surface of the stone to ensure even protection.

Finish

All sealers help protect granite surfaces, but some can leave behind a shiny finish that looks great.

A basic sealer helps create a shiny finish that reflects a bit more light than a non-sealed surface. An enhancing sealer provides a wet look, but to really create a bright, light-reflecting surface, a granite polish works best.

Polishing the granite surface creates a very glossy, shiny surface that can make an impact. Moreover, polishing the stone usually reduces the amount of tiny scratches that rob the granite of its light-reflecting properties.

Longevity

Sealing granite surfaces can take a bit of effort. For example, to seal granite flooring, the countertops must be cleaned and all furniture removed from the room.

Experts vary in their recommendations as to how often to seal granite, but most say it should be sealed every 3 months to once a year. In high-traffic areas, 3 months might be a good goal, while every 6 months may be enough for other places. Many of the best sealers can last several years.

Safety

The chemicals in granite sealers are no more dangerous than those in most popular household cleaners. Sealers need to cure to be effective. It may take a day or two for some sealers, but once cured, they’re completely safe to touch, prep food, and anything else you might do on a granite surface.

If it’s a solvent-based sealer, pay attention to the directions on the bottle. Many manufacturers suggest using these chemicals in a well-ventilated room, which can pose a challenge during colder months. However, once the solvent dissipates, which is rather quickly, the surfaces are safe.

Also, many manufacturers recommend that users wear gloves and safety glasses as they seal their countertops. Wearing a mask to avoid vapors or odors also might be a good idea.

Application

Considering how to apply the granite sealer is a major factor in choosing the best granite sealer. While a spray bottle might work well for a countertop, an aerosol probably works better on a large floor or shower. Also, some sealers need to sit on the surface longer than others to soak into the stone.

Understand what each sealer requires to provide adequate protection. Finding a stain because you missed a step is an expensive mistake that could cost a lot to remedy.

Versatility

In homes with a variety of different granite or stone surfaces, choosing a sealer that works on multiple surfaces may be the best bet. Stone sealers can work on multiple materials.

Most importantly, however, check that the product works specifically on granite. Granite has some different properties from stone like sandstone and marble, but some products will seal them all with one formula.

FAQs About Granite Sealers


The following section is a collection of the most frequently asked questions about granite sealers. If you still have questions about using the sealer, reach out to the manufacturer and speak with a customer service representative.

How often should you seal granite countertops?

Experts disagree as to how often granite should be sealed. A good rule of thumb is to test the surface every 3 to 6 months to determine if it needs sealing. To test it, simply drip a bit of water onto the granite and wait half an hour. If a damp ring appears around the puddle, you should seal the granite.

All the granite experts agree that no granite surface is exactly the same. In fact, darker colors like black, gray, and blue might not require much sealing at all

How long do you have to wait to use countertops after sealing granite?

Each product has its own curing time. Some cure within an hour, but most products take about 24 hours to cure completely.

Does granite sealer darken granite?

Sealers that penetrate the surface can give granite a darker appearance, but this is simply the sealer enriching the countertop’s color. It doesn’t actually darken the color, and it will lighten over time.
