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.

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.

The MORE Premium Stone Sealer is a water-based formula designed to protect a wide range of natural stones and grout both indoors and outdoors. It creates an invisible barrier that repels oil and water stains, which is ideal for surfaces like granite, marble, concrete, and more. This sealer offers good durability by bonding with stone pores, promising long-lasting protection that keeps liquids beading off the surface. Its finish is clear and natural, so it won’t alter the appearance of your stone.

Application is user-friendly: you can apply it with a brush, roller, or paint pad, let it absorb for around 15 minutes, and then wipe off any excess before it dries, which helps avoid uneven patches. Because it’s water-based and made from just four ingredients, this sealer has low odor and low VOCs, making it safer and more pleasant to use indoors without impacting air quality. One gallon covers about 1,000 square feet, which is efficient for large projects.

Careful application is necessary to avoid letting the product dry on the surface, which might be tricky for some users to master. While it’s water-resistant, extreme outdoor conditions or heavy wear might call for more specialized sealers. This product suits homeowners seeking a versatile, eco-friendlier stone sealer that balances ease of use with effective stain protection on multiple surfaces.
