The Black Diamond Stoneworks Wet Look Natural Stone Sealer offers a durable and long-lasting gloss finish for a variety of surfaces including pavers, slate, sandstone, travertine, and more. It enhances the natural beauty of stone with a 'Wet Look' without significantly darkening the surface once dried. The sealer is versatile in its application methods; it can be applied using a spray, brush, or roller, making it user-friendly for different surfaces like driveways, garage floors, patios, and masonry.

One notable strength is its chemical resistance, which ensures robust protection over time. However, it is important to conduct a small test area to ensure compatibility and desired results before full application, as results may vary depending on the stone type. The product is eco-conscious and proudly made in the USA, emphasizing quality craftsmanship.

On the downside, the product comes in a large and heavy 4-gallon container, weighing 36.54 pounds, which might be cumbersome for some users.

Despite these minor drawbacks, it stands as a solid choice for those looking to enhance and protect their stone surfaces with a glossy finish.

This sealer reduces water absorption by up to 95%, providing long-lasting protection for up to 7-10 years against cracking, spalling, ice and salt damage, and staining. The application is straightforward, requiring a pump sprayer, and it covers up to 225 square feet per gallon. One notable benefit is that it does not form a surface film, simplifying maintenance and reapplication. However, the sealer must be applied to properly cleaned and prepped surfaces for optimal performance.

The product's oil and water-resistant formula is particularly beneficial for outdoor use, as it resists weather elements and UV rays without yellowing over time. This durability can help maintain the appearance of surfaces for longer, saving users from frequent reapplications. Additionally, the application process is user-friendly, making it accessible even for those without extensive experience in sealing products.

Some users might find the drying time a bit lengthy, which could delay project completion if a quick turnaround is needed. While the sealer effectively protects against many stains, it may not be entirely foolproof against all types of oils or harsh chemicals, so caution is still advised in high-risk areas. Also, the VOC content, although safe for food applications, should be considered by anyone sensitive to chemical emissions.
