Rust-oleum 108402 Concrete Etching Solution 1 Gallon

Product Description

The RUST-OLEUM 108402 is a 1-gallon concrete etching solution formulated to chemically prepare bare concrete surfaces before the application of coatings, sealers, or paints. It works by opening the pores of the concrete, which promotes strong adhesion between the substrate and the finish coat. This type of surface prep product is standard practice in commercial and residential flooring projects, and it is commonly applied by flooring installers, painting contractors, and facility maintenance professionals. At 10.37 pounds per gallon container, it is a full-size working unit suited for job-site use.

This etching solution is used on bare, uncoated concrete floors, garage slabs, basement floors, and other horizontal concrete surfaces that require coating adhesion preparation. It is appropriate for both interior and exterior applications where concrete has not been previously sealed or painted. Contractors use it as a first step before applying epoxy floor coatings, concrete stains, or masonry sealers. A single gallon is sufficient for light to moderate coverage depending on concrete porosity and surface condition.

Key Features

• Chemically etches bare concrete to improve coating adhesion
• 1-gallon container suitable for single-job or smaller surface applications
• Ready-to-use formulation designed for standard concrete prep workflows
• Compatible with pre-coating surface preparation for epoxy, stain, and sealer systems

Compatibility

Designed as a surface preparation product for bare, uncoated concrete substrates prior to the application of compatible floor coatings, concrete stains, or masonry sealers.

Installation Notes

Application should be performed by a qualified painting or flooring contractor following the manufacturer's application guidelines. Ensure the area is well-ventilated and all personnel wear appropriate chemical-resistant PPE, including gloves and eye protection, before handling. Neutralize and thoroughly rinse the treated surface before applying any finish coat, as residual acid can interfere with coating adhesion. Dispose of spent solution and rinse water in accordance with local environmental regulations.
