10 Best Travertine Sealer 2025 in the United States

The Miracle Sealants 511 Impregnator is a water-based penetrating sealer designed for natural stone surfaces like travertine, as well as countertops, tile, and grout. As an impregnator sealer, it soaks deep into the stone to protect it from stains without creating a surface film, helping keep the natural look and feel of the stone intact. This product is known for its weather resistance, making it suitable for both indoor and outdoor use, and it is certified safe for food preparation areas, adding peace of mind if you’re sealing kitchen surfaces.

It also carries the SCS Certified Indoor Advantage Gold label, indicating low VOC (volatile organic compounds) content, which means it’s safer for indoor air quality compared to many solvent-based sealers. Application is relatively straightforward because it doesn’t require multiple coats or complicated steps, though some users might find that it needs reapplication every couple of years to maintain effective protection. The finish is natural, so it won’t add shine or gloss but will enhance the stone’s color subtly. In terms of coverage, it offers good spread, so a quart can cover a reasonable area depending on the stone’s porosity.

This sealer primarily functions as a stain protector rather than a hard surface shield, so it won’t guard against etching or surface scratches. For those seeking a product that preserves the stone’s appearance, is safe for indoor environments, and is easy to use, the Miracle Sealants 511 Impregnator is a reliable option, especially for travertine surfaces.

The Miracle Sealants High-Gloss Finish Sealer is a water-based sealer designed to protect and enhance interior stone surfaces, including travertine. It offers a high-gloss finish that brings out the natural color of your stone and adds a shiny, polished look that is low maintenance and won't yellow over time. This sealer is water resistant and features a low VOC, odorless formula, making it safer and more pleasant to use indoors. Its protective coating is UV transparent, which helps resist stains and scuff marks, contributing to durability.

Application is fairly easy, with the sealer drying to the touch in about 1 to 5 hours, and it covers between 500 and 1,500 square feet per gallon depending on surface porosity. However, the coverage range is quite broad, so you might need to apply more product on very porous travertine to get the best protection. The sealer is specifically compatible with terracotta and similar materials, which suggests it works well on natural stone floors but is mainly intended for interior use.

The packaging weight and size might be a little cumbersome if you're only sealing a small area. This sealer is a good choice for those wanting a glossy, protective finish on indoor travertine floors with an easy-to-use, low odor product. For heavy-duty or outdoor applications, or if you prefer a matte finish, you might want to consider other options.

The Black Diamond Stoneworks Wet Look Natural Stone Sealer is an excellent choice for those looking to enhance and protect travertine and other natural stone surfaces. One of its standout features is the enhanced gloss it provides, which gives surfaces a striking 'wet look' that amplifies the beauty of the stone. This makes it particularly appealing for homeowners wanting to revitalize their patios, driveways, or indoor stone features.

Applying the sealer is straightforward, as it can be used with a spray, brush, or roller. This versatility allows users to choose the method that works best for their project, making it accessible even for those who may not be very experienced with home improvement tasks. The product also maintains the natural appearance of most surfaces once dry, which is a significant advantage if you want to preserve the original look of your stone while still providing robust protection against chemicals and environmental wear.

However, there are some points to consider. While it is marketed as a durable and long-lasting sealant, the actual longevity can vary based on the specific conditions of use and the type of surface applied. Additionally, it’s essential to conduct a small test area before full application, as compatibility with certain stones or conditions can differ. Users who prioritize eco-friendliness may appreciate that this product is made in the USA and emphasizes quality craftsmanship, but it’s also important to check the VOC content if you are sensitive to chemicals. The 1-gallon size may not be sufficient for larger projects, so plan accordingly based on your coverage needs.
