Mapei Penetrating Stone Sealer, 1 Gallon, Used for Invisible Oil and Water Repellent Protection of Natural Stone and Grout

It’s suitable for sealing tile and stone surfaces, including ceramic, porcelain, and natural stone, as well as grout in many tile installations. It’s formulated for indoor and outdoor use.

Clean and dry the surface first. Apply evenly using a brush, roller, or spray, working in manageable sections. Do not leave excess wet slurry on the surface. Allow the sealer to penetrate and dry as directed by the product guidelines, then apply a second coat if required for additional protection. Recoat times and application specifics depend on surface porosity and environmental conditions.

One gallon covers up to approximately 150 square feet, depending on the porosity of the surface and the method of application.

Yes. It’s designed to perform well in both indoor and outdoor settings, providing protective sealing for high‑traffic areas such as kitchens, bathrooms, and exterior installations.

No. It is a non‑yellowing, penetrating sealer that won’t alter the color or texture of tile or stone surfaces.

The penetrating formula helps repel liquids, resist stains, and protect against dirt and everyday wear, contributing to easier maintenance and longer‑lasting beauty of the surface.

Use in a well‑ventilated area and wear appropriate PPE (gloves, eye protection). It’s water‑based and generally low odor, but always follow label instructions and ensure proper ventilation during application and curing.

Periodically evaluate the surface; if the surface shows reduced water repellency or increased staining, reapplication may be warranted. Clean the surface before reapplying and follow the same preparation and application steps as the initial sealant.
