10 Best Stone Sealers 2025 in the United States

The Miracle Sealants 511 Impregnator is a penetrating sealer designed for a wide range of stone and tile surfaces, both indoors and outdoors. Its main strength lies in its ability to create an invisible, oil- and water-resistant barrier that protects against stains, water damage, and even slippage, which is ideal for countertops and floors. It covers a large area—up to 4,000 square feet per gallon—making it economical for bigger projects.

The sealer is UV transparent, meaning it won’t yellow or discolor surfaces over time, and it resists weather elements effectively, so it’s suitable for outdoor use as well. Application is straightforward, and it’s safe to use around food prep areas, which adds to its versatility.

This sealer is a solid choice if you need durable, long-lasting protection for natural stone, tile, or grout, especially if you want something that won’t alter the look of your surfaces. The product weight and size might make handling a bit bulky for smaller projects.

The Miracle Sealants High-Gloss Finish Sealer is a water-based sealer designed mainly for interior stone and tile surfaces like terracotta. Its high-gloss finish enhances the natural color of your floors, giving them a shiny, low-maintenance look that stays clear without yellowing over time. It offers good durability with resistance to scuffs, wear, and stains thanks to a UV-transparent coating. The sealer is also water-resistant, which helps protect your surfaces from moisture damage.

Application is straightforward, covering a large area (500 to 1,500 square feet per gallon), and it dries fairly quickly within 1 to 5 hours, allowing you to complete your project in a reasonable time frame. Another plus is its low VOC (volatile organic compounds) content and odorless formula, making it safer and more pleasant to use indoors. This product is specifically suited for interior use and materials like terracotta; it may not be the best choice for outdoor surfaces or other stone types. Also, while water-resistant, it is not fully waterproof, so heavy exposure to water might require a different sealer.

The product comes in a gallon size, but the packaging weight indicates small individual containers in a 4-pack, which may affect how you plan your application. This sealer is a solid option for anyone seeking an easy-to-use, attractive finish for indoor stone floors with good protection and minimal fumes.

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.
