Stanley Works Tools 47-821 Xtreme Red Chalk 8 Oz

Product Description

The STANLEY WORKS TOOLS 47-821 is an 8-ounce bottle of Xtreme red chalk powder used with chalk reel tools to snap layout lines on job site surfaces. The high-visibility red pigment produces bold, easy-to-read lines on concrete, wood, drywall, and masonry. At 0.61 pounds, the compact bottle fits standard chalk reel reservoirs and is sized for straightforward refilling in the field. Tradespeople across framing, layout, and rough-in work rely on chalk lines to establish reference points quickly and accurately before cutting or fastening.

This chalk powder is suited for interior and exterior layout tasks including stud layout, tile setting reference lines, roofing courses, and subfloor grid marking. The red color is preferred when working on surfaces where white or blue chalk would be difficult to see, such as weathered lumber, gray concrete, or existing drywall mud. It is used by carpenters, masons, tile setters, roofers, and general contractors on both residential and light commercial projects.

Installation Notes

Fill the chalk reel reservoir in a controlled manner to avoid overfilling or spilling powder onto finished surfaces. Snap lines in a single controlled motion for the cleanest mark. Red chalk can be more difficult to remove from porous surfaces than white or blue chalk, so avoid marking areas where permanent staining is a concern. No special tools or codes apply to chalk line use beyond standard jobsite safety practices.
