Best Sealer For Granite Counters FAQs

Can you use any sealer on granite counters?

No, you cannot use any sealer on granite counters. Granite is a natural stone that is porous and can absorb liquids and stains if not properly sealed. Therefore, it's important to choose the right sealer for your granite countertops. There are different types of sealers available in the market, including penetrating and topical sealers. Penetrating sealers are absorbed into the granite and provide long-lasting protection, while topical sealers sit on the surface of the granite and offer temporary protection.

It's important to note that not all sealers are suitable for all types of granite. Some sealers may cause discoloration or damage to your countertops if not used correctly. To ensure you're using the right sealer for your granite countertops, you should consult with a professional or read the manufacturer's instructions carefully. Additionally, it's important to reseal your granite countertops periodically to maintain their luster and protect them from stains and moisture.

How often should granite counters be sealed?

Granite counters should be sealed at least once a year. However, the frequency of sealing depends on the type of granite, usage, and exposure to acidic substances. Some granite types are more porous than others and require more frequent sealing. For instance, lighter and more porous granites like Kashmir White and Santa Cecilia may require sealing every six months, while darker and denser granites like Absolute Black and Ubatuba can go for up to two years without sealing. Additionally, if your granite counter is exposed to acidic substances like vinegar, citrus juice, or wine, you may need to seal it more frequently. Acidic substances can etch the surface of the granite, making it more susceptible to staining and bacteria growth. In summary, it is advisable to follow the manufacturer's recommendations and consult with a professional to determine the best sealing frequency for your granite counter.

Is there a specific brand of sealer that is recommended for granite counters?

Yes, there are several brands of sealers that are recommended for granite counters. The most popular ones are Stone Care International Granite Sealer and Protector, Black Diamond Stoneworks Granite Sealer, and Granite Gold Sealer. These brands are specifically designed to provide a protective layer that prevents stains, scratches, and other damages on granite counters. It is important to note that not all sealers are created equal, and some may contain harsh chemicals that can damage the countertop. Therefore, it is important to choose a sealer that is specifically formulated for granite and to follow the manufacturer's instructions carefully. Additionally, it is recommended that granite counters be sealed at least once a year to maintain their durability and appearance.

What is the process for applying sealer to granite counters?

The process of applying sealer to granite counters is fairly simple and straightforward. First and foremost, ensure that the granite counters are clean and dry before applying the sealer. Next, select a high-quality sealer that is suitable for granite surfaces. There are a variety of sealers available in the market, so it is vital to choose the one that works best for your specific type of granite.

Once the sealer has been chosen, apply it to the granite counters in a thin, even coat using a clean cloth or brush. Make sure to cover the entire surface of the counter, including the edges and corners. Allow the sealer to penetrate the granite for the recommended time specified on the product label.

After the recommended time has passed, wipe off any excess sealer with a clean cloth or paper towel. It is important to remove all the excess sealer, as leaving it on the surface can result in a hazy appearance. Allow the sealer to dry completely before using the granite counters.

It is also essential to reapply the sealer periodically, as recommended by the manufacturer, to maintain the granite's protective layer. The frequency of reapplication will depend on the type of sealer and the amount of use the granite counters receive.

What type of sealer is best for granite counters?

When it comes to sealing granite counters, it is important to choose the right type of sealer that will provide long-lasting protection against stains and spills. There are two main types of sealers that are commonly used for granite counters: topical sealers and penetrating sealers.

Topical sealers are applied on the surface of the granite and form a protective layer that prevents liquids from penetrating the stone. While they provide good protection against stains, they tend to wear off over time and need to be reapplied frequently.

Penetrating sealers, on the other hand, penetrate the pores of the granite and provide a long-lasting barrier against stains and spills. They do not alter the appearance of the stone and are less likely to wear off over time. However, they may not be as effective against acidic substances like vinegar or lemon juice.

Ultimately, the best type of sealer for your granite counters will depend on your specific needs and preferences. It is important to choose a high-quality sealer that is designed specifically for granite and to follow the manufacturer's instructions for application and maintenance.
