10 Best Granite Sealers 2025 in the United States

The Weiman Complete Countertop Clean & Protect Kit is designed to clean, polish, and seal natural stone surfaces like granite, marble, and quartz, making it a versatile choice if you want an all-in-one solution. It comes with two sprays: one to clean and shine, and another to seal and protect. This setup works well for daily or weekly maintenance, which is convenient for keeping stone looking fresh without extra hassle. The sealer forms a protective barrier that helps prevent stains from grease, water, and soil, which is important for maintaining the stone’s appearance over time.

Since it is a spray, applying the sealer is straightforward and less messy compared to some other products that require wiping or brushing. It is meant for non-porous sealed surfaces, so it’s not ideal for unsealed or very porous stone types. The finish leaves a polished look, enhancing the stone’s natural beauty without a dull or overly shiny effect. One limitation is that it may need regular reapplication to maintain protection, especially in high-use areas like kitchen countertops.

While it offers good water resistance, very heavy or prolonged exposure to liquids might still require extra care. This kit is a solid option for homeowners who want to protect and maintain their stone surfaces easily, with a product suitable for multiple stone types and surfaces around the kitchen and bathroom.

The STONETECH Bulletproof Sealer is a solid choice for anyone looking to protect their porous natural stone surfaces, especially granite. One of its key strengths is its durability; it offers protection for up to five years on interior surfaces, which is impressive compared to many other sealers on the market. This longevity means less frequent reapplication, saving you time and effort in the long run.

Another notable advantage is the ease of application. The water-based formula allows for straightforward use, and it’s compatible with a variety of stone materials, making it versatile for different projects. Additionally, it provides good coverage, protecting up to 100 square feet, which is beneficial for larger areas.

When it comes to stain and water resistance, this sealer excels, effectively preventing both stains and moisture from penetrating the stone. This feature is crucial for maintaining the aesthetic and structural integrity of your granite surfaces.

The Weiman Disinfecting Granite & Stone Daily Cleaner and Sealer Kit is designed for those who want to maintain and protect their granite and other stone surfaces. This kit includes a 24 oz daily cleaner and a 24 oz sealer, making it convenient for regular maintenance. One of its standout features is its disinfecting ability, killing 99.9% of germs and bacteria in just 10 minutes, which ensures a hygienic kitchen or bathroom environment.

It's suitable for multiple stone surfaces like granite, marble, quartz, quartzite, and slate, providing versatility in its application. The cleaner leaves surfaces streak-free and shiny, enhancing the natural beauty of the stone. The sealer, on the other hand, creates a protective barrier that repels water and soil, helping to prevent stains and prolong the lifespan of your stone surfaces. The durability of the sealer might require periodic reapplication, which can be a hassle for some users.

The application process is straightforward, using a spray bottle for both products, but it might take some time to ensure even coverage. The finish is aesthetically pleasing, leaving surfaces looking polished and well-maintained. In terms of stain resistance, it does a good job but might not be as effective against very tough stains. Water resistance is another strong point, as the sealer effectively prevents water penetration. This product is a good fit for homeowners looking for a comprehensive solution to clean and protect their stone surfaces, though it may not be the best choice for those looking for a one-time, long-lasting sealing solution.
