Description
Permanent Formulation: Specifically engineered as a permanent exterior chalk. It remains sharply visible even after weeks of exposure to heavy weather, rain, and punishing job-site foot traffic.
Surface Versatility: Leaves bold, crisp red lines on a massive variety of demanding surfaces including raw lumber, concrete, brick, stone, and asphalt.
Airtight Packaging: Packaged in a heavy-duty 5 lb. bulk container featuring an innovative flip-top cap. The cap forms an airtight seal to completely shut out moisture, keeping the chalk dry and eliminating the risk of internal clumping.
