Strait-line Marking Chalk, Crimson Red, Exterior, 6 Oz.

Irwin Strait Line 6 oz. Crimson Red Powder Chalk is a permanent staining marking chalk for exterior use. It is visible after weeks of weather exposure and jobsite wear. It stains the surface and reduces the need to spray sealant. IRWIN STRAIT-LINE Marking chalks have a newly engineered flip-top cap that keeps the chalk in the bottle where you want it and stops it from spilling out in areas that you don't. The flip-top cap, available on all IRWIN STRAIT-LINE chalk bottles, seals the chalk in an air-tight chamber, keeping out moisture and reducing the risk of clumping.
