LATICRETE® 190 Sealer is a high-performance penetrating sealer formulated to create an invisible, water-repellent barrier on a wide range of porous surfaces including marble, limestone, brick and mortar joints. It penetrates deep into the substrate, reducing water absorption and protecting against stains while maintaining the natural look and finish of the surface.

Designed for both interior and exterior applications, this sealer enhances durability by shielding installations from weather-related damage such as rain exposure and efflorescence. It also serves as an effective grout release when applied to ceramic tiles prior to grouting, preventing grout haze and simplifying post-installation cleaning. Its water-based, non-flammable composition ensures safe and environmentally responsible usage, making it suitable for residential as well as commercial projects.
