Irwin 2032160 5lb Black Permanent Marking Chalk

Lines that last. Contrast that pops. The Irwin 2032160 Black Permanent Chalk is engineered for environments where standard chalk fails. Designed for maximum "grab," this high-pigment formula produces the most visible line possible on dark asphalt, weathered concrete, and shingles. When the job requires a layout that stays sharp through wind, dust, and light rain, Black is the professional's only choice.

Engineered for Brutal Conditions:

• Permanent Grade Pigment: Formulated for maximum endurance. This chalk is designed to leave a lasting mark that resists fading and foot traffic, making it ideal for multi-day framing and roofing projects.
• Extreme Contrast: Provides a sharp, aggressive black line that stands out brilliantly on light-colored concrete and grey roofing materials.
• Weather & Moisture Resistant: Specially milled to resist clumping inside your reel. Even in humid coastal or morning-dew conditions, this chalk pours smooth and snaps clean.
• Industrial 5lb Bulk Value: The high-volume jug features a reinforced easy-pour spout and a tight-sealing cap, ensuring your chalk stays bone-dry in the back of the truck.
• Anti-Friction Formula: Finely ground to reduce internal wear on your chalk reel's line and gears, extending the life of your layout tools.

⚠️ PRO TIP: Black chalk is permanent. Use this for exterior layouts, roofing, or subfloors that will be covered. For finished interior surfaces, we recommend Irwin Blue.
