Rust-oleum 353619 Concrete Densifier 1 Gallon Clear

Product Description

The RUST-OLEUM 353619 is a ready-to-use, water-based concrete densifier formulated to penetrate and chemically bond with concrete substrates. It increases surface hardness, improves abrasion resistance, and reduces surface dusting for healthier indoor air quality. When used as part of a mechanical polishing process, it enhances color, gloss, and clarity for decorative concrete applications. At 9.5 pounds per gallon container, it ships ready to apply with no mixing required. Flooring contractors, concrete finishers, and facility maintenance crews are the primary installers of this product.

The 353619 is suited for both new pours and existing concrete surfaces in residential, commercial, and industrial settings. Typical applications include warehouse floors, retail spaces, garages, and interior slabs where increased surface durability and a polished aesthetic are required. It performs on horizontal concrete surfaces that will undergo mechanical polishing as part of a multi-step finishing system. It is not intended for vertical surfaces or non-concrete substrates.

Key Features

• Chemically bonds with concrete to increase hardness and longevity
• Reduces concrete dusting to support healthier indoor air quality
• Enhances polished color, gloss, and clarity when used with mechanical polishing
• Improves stain resistance on treated surfaces
• Ready to use directly from the container — no dilution or mixing required
• Water-based formula with no odor and quick return to service

Compatibility

Designed for use on new or existing concrete surfaces as part of a mechanical concrete polishing system. Best applied when air, material, and floor temperatures are above 35 degrees F and rising, and relative humidity is below 85 percent.

Installation Notes

Application is typically performed by concrete flooring contractors or experienced finish crews using standard floor equipment. Ensure the concrete surface is clean, structurally sound, and free of curing compounds or coatings that would prevent penetration. Follow all applicable safety guidelines for surface preparation and ventilation as required by local codes. Allow adequate cure time before returning the floor to service traffic.
