Keson ProChalk, Standard
Keson ProChalk Standard is an all-purpose marking chalk designed for temporary, high-visibility lines on a variety of surfaces. It is ideal for indoor and outdoor use, providing clear, crisp lines that are easily visible but intended for shorter-term marking tasks. The standard formula is best suited for general construction, layout, and marking jobs where the chalk may need to be brushed off or washed away later. This chalk is reliable for projects requiring temporary yet accurate markings on surfaces like wood, concrete, and asphalt.
