10 Best Granite Sealers 2026 in the United States

The Wet Look Natural Stone Sealer by Black Diamond Stoneworks is a versatile and durable sealer that provides a lasting glossy finish. It's especially effective for enhancing the appearance of various surfaces like pavers, slate, and driveways, both indoors and outdoors. The sealer is designed to deliver a 'wet look,' which amplifies the natural beauty of the stone without significantly darkening it post-application. This makes it suitable for those who wish to maintain a natural appearance while adding a layer of protection.

This sealer stands out due to its ease of application, as it can be applied using a spray, brush, or roller, catering to both professionals and DIY enthusiasts. It's also noteworthy for its resistance to chemicals, making it ideal for protecting surfaces in areas exposed to potential spills or harsh conditions. Additionally, it's manufactured in the USA, which may appeal to those who prefer domestically produced goods.

In terms of drawbacks, users might find that the 'wet look' finish might not be to everyone's taste, especially if a completely natural, matte finish is desired. Furthermore, the instruction to test a small area beforehand implies that the sealer may not be universally compatible with all stone types, which could require careful consideration and potentially additional steps in the application process. For those seeking an easy-to-apply, glossy finish that enhances and protects stone surfaces, this sealer could be a great choice. However, it's essential to ensure compatibility with your specific stone type to avoid unintended results.

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 Weiman Granite & Stone Sealer Spray is a water-based sealer designed to protect a variety of stone surfaces, including granite, quartz, marble, tile, limestone, and slate. This product is particularly suitable for countertops, sinks, showers, vanities, and floors. Its water-resistant formula helps to repel water and soil, preventing stains and maintaining the appearance of your stone surfaces. The sealer is pH neutral and ammonia-free, making it gentle yet effective for regular use.

Applying the sealer is straightforward, and the product's 24-ounce size makes it convenient for multiple applications. Regular use, typically every 6 months, is recommended to keep surfaces well-protected. Some users might find the need for periodic reapplication a minor inconvenience. Additionally, while the product is effective in providing a good finish and stain resistance, it may not be the most durable option compared to other heavy-duty sealers.

The Weiman Granite & Stone Sealer Spray is a reliable choice for those seeking an easy-to-use, gentle, and effective solution for maintaining their stone surfaces.
