Engineered for professionals who demand performance in all conditions, the STANLEY® FATMAX® XTREME™ Red Chalk (Model 47-821) delivers superior line visibility, weather resistance, and jobsite reliability. This 8 oz (227g) bottle of high-performance chalk is specially formulated to snap longer-lasting, fade-resistant lines that adhere to both wet and dry surfaces, making it ideal for exterior masonry, concrete, and rugged framing work.

Key Features:

• Weather-Resistant Formula:
  Designed to perform in the harshest environments, this chalk resists fading, bleeding, and clumping—even in wet conditions. It maintains line integrity in rain, humidity, and on damp surfaces.

• High Visibility Red Color:
  The bold red pigment ensures maximum contrast and visibility on rough or dark surfaces, making it perfect for outdoor use where precision matters.

• Non-Clumping & Low-Mess Application:
  The advanced powder formulation reduces chalk waste and prevents clumping inside chalk reels, ensuring smooth, consistent line snapping with minimal mess.

• Ergonomic, Jobsite-Ready Bottle:
  The square-shaped bottle is designed to stay put—no rolling off work surfaces. It features an easy-pour spout and a tethered pop-off cap to prevent loss and simplify refills.

• Durable & Permanent Marking:
  Once applied, the chalk lines are indelible and built to last, making them ideal for long-term layout work.
