Stanley FatMax Xtreme 47-827 Red Chalk 5 Pound Refill Waterproof High Visibility Snap Line Chalk for Reels Professional Construction Grade Layout Tool

Industrial-Strength Waterproof Layout Chalk for the Most Demanding Jobsites

The Stanley FatMax Xtreme 47-827 5-Pound Red Chalk is engineered for professionals who cannot afford for their layout lines to disappear. This premium waterproof chalk is specially formulated to resist fading and bleeding, even in high-moisture or wet environments. Whether you are snapping lines on damp concrete or working through a humid morning, this chalk ensures your marks stay sharp and visible, providing the precision needed for framing, roofing, and general layout tasks.

Efficiency is built into the design of the packaging as well. The large 5-pound high-capacity bottle features a square shape to prevent it from rolling off slanted work surfaces or tailgates. The formula is optimized to eliminate clumping inside your chalk reel, ensuring a smooth, consistent flow and even coating on the line every time you pull. With its vibrant red pigment, this chalk provides a high-contrast mark that stands out against nearly any building material, making it a staple for heavy-duty construction and industrial use.

Pro-Tip: To achieve the cleanest line, give your chalk reel a few good shakes before extending the string. When working on highly porous surfaces, "snap" the line twice—once to clear excess dust and a second time for a razor-sharp, permanent mark.
