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 Plus Stone Sealer is a water-based liquid designed to protect a wide range of natural stone surfaces, including marble, granite, quartzite, and more. It offers strong stain resistance by creating a barrier that stops food and drink spills from soaking in, which is especially helpful for kitchen countertops. The sealer also helps prevent buildup of grime and harmful films, keeping surfaces looking cleaner longer. Its water-based formula means it has low odor, making it comfortable to apply indoors or outdoors. Application is straightforward and homeowner-friendly, taking about an hour to apply, with no special tools or skills needed.

Once applied and properly maintained, the sealer can protect surfaces for up to 10 years, providing a solid durability period for stone sealers in this price range. The finish is clear, so it won’t change the natural look of your stone. While it is water-resistant, it may not be fully waterproof against heavy or constant moisture exposure. The product does not specify exact VOC (volatile organic compound) content, but being water-based generally indicates lower VOCs than solvent-based sealers, which is better for indoor air quality.

Weighing 8 pounds for the gallon size, it offers good value for covering large areas or multiple surfaces. This sealer is a reliable choice for homeowners looking for an easy-to-use, effective protective layer on natural stone countertops without harsh chemicals or complex application.
