Rust-oleum 511QT6 Impregnator Penetrating Sealer 1 Quart

Product Description

The RUST-OLEUM 511QT6 is a quart-size impregnator penetrating sealer formulated to protect medium to dense porous surfaces. The sealer absorbs below the surface to form an invisible barrier that resists moisture and stains without altering the natural appearance of the material. Treated surfaces become harder and less slippery after application. Because the sealer is vapor-permeable, it allows moisture vapor to escape rather than trapping it beneath the surface. This product is suitable for installation by tile setters, stone masons, flooring contractors, and experienced trade professionals working with natural and manufactured porous materials.

This sealer is used on a wide range of porous surfaces in both residential and commercial applications. Typical installation scenarios include protecting natural stone, tile, grout, concrete, brick, and similar masonry surfaces on floors, walls, countertops, and exterior flatwork. It is applied before or after grouting on new installations and as a maintenance treatment on existing surfaces that require renewed stain and moisture protection.

Key Features

• Penetrating impregnator formula absorbs below the surface for protection that does not peel or flake
• Forms an invisible barrier resistant to moisture and stains
• Vapor-permeable — allows moisture vapor to escape while blocking liquid intrusion
• Will not alter the natural color or finish of treated surfaces
• Treated surfaces are harder and less slippery after sealing
• Suitable for all medium to dense porous surfaces

Compatibility

Designed for use on medium to dense porous surfaces including natural stone, tile, grout, concrete, brick, and similar masonry substrates in residential and commercial settings.

Installation Notes

Application is typically performed by a tile setter, stone installer, or flooring contractor using a brush, roller, or clean cloth per standard masonry sealer procedures. Ensure the surface is clean, dry, and free of previous coatings or contaminants before applying. Allow adequate cure and dry time before exposing the surface to moisture or foot traffic. Follow all manufacturer application instructions and local safety guidelines for ventilation when working in enclosed spaces.
