How to use

Fill the chalk reel or applicator with the chosen Stanley Chalk Powder following the tool manufacturer’s instructions. For cartridge formats, insert the cartridge into a compatible chalk reel. Apply by pulling the line taut and snapping to transfer a straight mark; for freehand marking, sprinkle or dust the powder onto the surface as needed. Allow marks to set; reapply if necessary for faded lines. Clean the applicator after use to prevent clogging.
