10 Best Granite Sealers 2025 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 STONETECH Bulletproof Sealer is a water-based, penetrating sealer designed to protect porous natural stones, tile, masonry, and grout. It offers strong stain resistance against both oil and water-based spots, making it a solid choice for keeping stone surfaces clean and well-protected. Because it penetrates deeply and is breathable, it preserves the natural appearance without creating a shiny or artificial finish. The water-based formula is low in odor and non-flammable, which makes it safer and more pleasant to apply indoors or outdoors. Its protection lasts well under normal cleaning conditions, showing good durability for everyday use.

Application is fairly straightforward since it’s a liquid, though precise directions should be followed for best results. One slight downside is that it’s rated as water-resistant rather than fully waterproof, so it might need reapplication in very wet or high-use areas over time. It’s also best suited for porous materials like terracotta and tile, so it may not be ideal if you’re sealing very smooth or dense stone. This sealer serves as a dependable, professional-grade option for those needing solid stain and water protection on porous stone surfaces, with an easy and environmentally friendly application process.

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.
