Keson - Lumber Crayons - CLEARANCE

Make bold, legible layout marks that survive the jobsite. Keson lumber crayons deliver dense, high-contrast lines on rough materials—framing lumber, OSB/plywood, concrete forms, masonry, and steel. The durable wax/ pigment blend resists crumbling, won’t wash out at the first hint of moisture, and glides smoothly for fast, consistent marking. Sized to fit standard crayon holders and pockets, they’re the everyday staple for framers, carpenters, masons, and fabricators.

Key Features

• Pro-grade mark quality: Dense, highly visible lines that read on rough, dusty, or uneven surfaces.
• Durable composition: Tough wax/pigment blend resists breaking, glazing, and premature wear.
• Multi-surface performance: Sticks to wood, concrete, masonry, metal, and plastic forms.
• Moisture & weather resistant: Marks hold up in damp conditions and light rain (always test your surface).
• Smooth application: Low drag for quick, controlled lines and legible text.
• Color options: Common construction colors available (e.g., red, blue, black, yellow, white) for codes and visibility needs.
• Standard size: Compatible with most lumber-crayon holders/holsters; easy pocket carry.
• Jobsite ready: Rectangular/oval profile won’t roll off surfaces; beveled edges for crisp scribing.

Q: What surfaces do these lumber crayons mark best?
A: Wood, OSB/plywood, concrete forms, masonry, and primed steel. They can mark some plastics, but always test first for adhesion and cleanability.

Q: Are the marks moisture- or weather-resistant?
A: They resist light moisture and smudging, but they’re not permanent like paint. For heavy rain or long-term outdoor durability, use a more permanent marking solution.

Q: Will these crayons fit my holder?
A: Yes—these are the standard rectangular/oval lumber-crayon size and fit most holders and holsters, including PS100-style collet holders.

Q: Any tips for sharpening and cleanup?
A: Knife or sand the tip to a bevel for crisp scribing. Store cool and dry to prevent softening. To remove marks, scrape or wipe; on sealed/finished surfaces, start gentle and test a mild solvent if needed.
