How contractors use it

Crews fill a chalk reel with this blue chalk to snap straight reference lines for trim, panel layout, control joints, and base-track placement on EIFS, stucco, and masonry jobs. Because it is temporary, blue is the standard choice when the lines do not need to stay after the work is set.
