Most common uses

Construction and carpentry experts will appreciate the caliber of our PRO Lumber Crayons. Also available are our Fluorescent scannable lumber crayons which are used by sawmills that have  UV (Ultraviolet) and GMR (Grade Mark Reader) scanning equipment.

Construction: Can include literally any work where wood is involved.  Framing, flooring, roofing, structural to trim.  Whether marking on hardwood, softwood, panels, plywood, particleboard, fibreboard, OSB (Oriented Stranded Board) or other, Carmel’s Lumber Crayons are the solution.  Various wood strands, fibers, veneers, or other forms of composite materials used for specific construction applications.  Be it raw or engineered wood, these are commonly used in a wide variety of residential, commercial and industrial construction projects.

Logging and millwork: The colours are highly visible and work great with almost any species of lumber.  The red or yellow are recommended on darker wood  (such as walnut) and red or black on light coloured woods (like maple or poplar).  The contrast of colours make the lines stand out much better when you’re laying out your cut lines for larger rough cuts.

Indeed, Carmel’s Lumber Crayons are perfect for initial rough work and even writing out component names and dimensions for when it’s time to cut the pieces.  Our stronger clay-based formula is made tough for reduced breakage and longer marking life.

Why not use regular crayons or markers?

Carmel Lumber Crayons apply a solid layer of coloured clay to the surface instead of liquid ink or paint. This allows lumber crayons to work on a much wider range of materials. As they are solid, and do not make use of a felt or plastic tip to transfer paint, they don’t need to be replaced often due to wear. This also means that our harder crayons work well on wood and rougher materials like concrete.
