With a clear finish that won't alter the appearance or color of your surfaces, it preserves the natural look while offering robust water repellency.

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.

At 44 pounds, the 5-gallon container may be cumbersome for some users. This product is highly rated with 4.6 out of 5 stars from over 1,000 reviews, indicating strong customer satisfaction.

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. Additionally, while it aims to maintain the stone's natural appearance, it may not suit those looking for a sealer with minimal or no change in visual gloss. Despite these minor drawbacks, it stands as a solid choice for those looking to enhance and protect their stone surfaces with a glossy finish.

Miracle Sealants 511 Porous Plus is a penetrating sealer designed for both indoor and outdoor use on porous surfaces like countertops, flagstone, sandstone, and terra cotta. It creates an invisible, water- and oil-resistant barrier that helps protect against stains, water damage, and even slippage, making it a strong choice for areas prone to spills or moisture. One of its highlights is excellent coverage—up to 4,000 square feet per gallon—so a single container can cover a large area, which is cost-effective for big projects.

The sealer is UV transparent, meaning it won’t yellow or darken over time, maintaining the natural look of your stone even in sunlight. Application is straightforward, and it’s safe for use around food prep areas, which is a key benefit for kitchen countertops. Since it’s a penetrating sealer, it won’t add a glossy or shiny finish but rather a natural look, so if you want a glossy effect, this might not be the right pick.

This product offers durable and versatile protection for porous stone surfaces from everyday wear and staining, especially suited for those who prefer a natural finish without altering the stone’s appearance.
