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.

Aqua Mix Sealers Choice Gold is a premium sealer designed for a variety of stone surfaces, including granite, marble, and tile. One of its standout features is its maximum stain resistance, which is essential for maintaining the beauty of natural stone. The water-based formula is a plus, as it allows for easier cleanup and is environmentally friendly. This sealer can be used both indoors and outdoors, making it versatile for different applications.

The ease of application is another appealing aspect; it doesn't require any complicated processes, making it suitable for DIY enthusiasts. Users generally find it straightforward to apply, and the clear finish ensures that the natural look of your stone is preserved.

While it boasts water resistance, it may require reapplication every couple of years, especially in high-traffic areas or when exposed to harsh weather conditions. It's also important to ensure thorough surface preparation before applying, as improper application can lead to unsatisfactory results.

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.
