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.

There are a few considerations to keep in mind. While it works great on a variety of surfaces, it may not be as effective on heavily stained or neglected areas, which might require a more intense cleaning or preparation before sealing. Additionally, although it's designed for DIY application, those who are inexperienced might find the application process a bit tricky initially, so following the instructions carefully is essential.
