Irwin 64902 Red Chalk Powder 8 Oz 6 Pack

Product Description

The IRWIN INDUSTRIAL TOOL CO 64902 is a red chalk powder packaged in a plastic bottle, sold in a case of six 8-ounce units. Chalk powder is used with chalk line reels to snap visible layout lines on floors, walls, ceilings, and other work surfaces. Red chalk produces a high-contrast line that stays visible on concrete, wood, drywall, and similar substrates. The 8-ounce bottle refills most standard chalk line reels quickly without mess. This product is commonly kept on the truck by carpenters, framers, masons, flooring installers, and general contractors who need reliable, repeatable layout lines throughout the workday.

Red chalk powder is suited for layout work where a bold, easily seen line is needed, including framing layout on concrete slabs, tile and flooring grid lines, roofing layout, and general construction marking. Because red chalk is more permanent than blue chalk on porous surfaces, it is preferred when the line must remain visible through multiple stages of a job. The case pack of six bottles supports ongoing jobsite use without frequent restocking.

Key Features

• Red color provides high-contrast, easily visible layout lines on light and dark surfaces
• 8-ounce fill per bottle suits most standard chalk line reels
• Plastic bottle with controlled pour opening for clean, accurate refilling
• Packaged 6 units per case for efficient jobsite and shop inventory
• More permanent line on porous surfaces compared to standard blue chalk

Compatibility

Designed for use with standard chalk line reels that accept powdered chalk refills. Check your reel manufacturer's guidelines for recommended chalk color and coarseness.

Installation Notes

Fill the chalk line reel in a controlled environment to avoid spilling powder on finished surfaces, as red chalk can be difficult to remove from porous materials. Keep the bottle cap seated firmly when not in use to prevent moisture from clumping the powder. No special tools or codes apply to chalk line use, but installers should follow project specifications when selecting chalk color, as some inspection requirements or finish trades may require removable chalk rather than a permanent line.
