Irwin Strait-Line Marking Chalk Refill is a permanent staining marking chalk designed for exterior use on jobsites, construction projects, and outdoor work. This crimson red chalk creates visible, lasting lines that remain clear even after weeks of weather exposure, rain, and sun. Unlike temporary chalk that washes away, this formula stains the surface permanently, reducing or eliminating the need for additional protective sealants or spray applications.

The 6-ounce refill bottle features Irwin's engineered flip-top cap, which seals the chalk in an air-tight chamber to keep moisture out and prevent clumping during storage. The flip-top design also prevents the chalk from spilling out of the bottle in areas where you don't want it, keeping your workspace cleaner and your chalk supply intact longer.

Features and Benefits

  • Permanent Staining Formula: Creates visible marks that withstand weather exposure and jobsite conditions for weeks without fading.
  • Exterior Grade: Engineered for outdoor use with resistance to rain, sun, and environmental wear.
  • Flip-Top Air-Tight Cap: Seals moisture and reduces clumping, extending product life and preventing accidental spills.
  • Surface Staining Action: Eliminates the need for extra protective coatings or sealant applications, saving time and materials.
  • 6-Ounce Capacity: Ample volume provides extended use on multiple projects before refilling.
