Advanced Water & Weather Proofing: Engineered with specialized hydrophobic pigments that will not wash away under heavy rain, ensuring permanent layout tracking on foundational slabs.

High-Wind and Wet Substrate Stability: Formulated with high-density microparticles that resist drifting or blowing away on exposed job sites. It successfully bonds to damp materials once standing water is cleared.

Clean, Reduced-Smudge Lines: Drops a highly visible, deep black snap line on masonry, concrete, and framing timber with minimal ghosting or tracking.

Convenient Refill Spout: Housed in a portable 8 oz. squeeze bottle with a targeted pour snout to eliminate clumping and mess during on-site reel fill-ups. It remains non-toxic and washes out of work wear with soap and water.
