Rust-oleum 205236 Inverted Marking Chalk Spray 17 Oz

Product Description

The RUST-OLEUM 205236 is a water-based inverted marking chalk in a 17 oz aerosol can, engineered for fast, legible temporary line marking on job sites and utility work. It sprays in the inverted position, allowing the applicator to mark surfaces without bending. The formula becomes scuff resistant in 10 minutes and produces bright, vivid lines that hold up on concrete, asphalt, gravel, grass, brick, and dirt for up to 30 days. Licensed contractors, utility locators, and survey crews use this product for surface identification, layout, and hazard marking.

This marking chalk is suited for outdoor applications where clear, temporary delineation is required. Typical use cases include underground utility locating, construction layout, landscaping boundaries, and pavement marking. The water-based formula is designed for use across a range of exterior surfaces and is compatible with standard marking applicator tools. Marks can be removed with a wire brush or power washing when the job is complete, making it practical for temporary staging areas and permitted excavation zones.

Installation Notes

This product is applied by utility locators, surveyors, and construction tradespeople — no specialized licensing is required for surface marking use. Shake the can thoroughly before use and verify surface is reasonably dry and free of standing water for best adhesion. Follow all applicable local requirements for color-coding utility markings, such as APWA Uniform Color Code standards. Do not use near open flame or heat sources, and store in a cool, well-ventilated area per the product safety data sheet.
