About Crayons

Professional marking crayons are indispensable tools for tradespeople working across construction, automotive, and manufacturing sectors. Unlike standard art crayons, these industrial-grade markers are engineered to write clearly on challenging surfaces including metal, wood, concrete, rubber, and glass. Whether marking cut lines on timber, identifying components in workshops, or marking tyres for rotation, professional crayons deliver visible, durable marks that withstand harsh site conditions.

MyToolShed.co.uk stocks specialist marking crayons from trusted brands including Strait Line, Faithfull, Markal, and Sealey. These marking tools are designed for demanding environments where standard pens and pencils simply won't perform. Available in various colours including high-visibility yellow and traditional black, professional crayons offer excellent coverage and can mark through oil, dirt, and moisture. Their robust construction means they won't break easily in toolboxes or site bags, making them practical for mobile tradespeople.

Applications

Professional marking crayons are used daily across a wide variety of trades and industries:

• Carpenters and joiners marking cut lines, measurements, and assembly points on timber
• Steel fabricators and welders marking metal components for cutting, drilling, and welding
• Builders and general contractors marking positions on various construction materials
• Tyre fitters and automotive technicians marking tyres for rotation, balancing, and identification
• Warehouse and logistics personnel marking packages, pallets, and inventory items
• Plumbers and heating engineers marking pipe cut points and installation positions
• Roofers marking slate, tile, and metal roofing materials
• Electricians marking cable runs and mounting positions on various surfaces
• DIY enthusiasts tackling home improvement and workshop projects

Choosing The Right Crayons

Surface Material: Consider what you'll be marking most frequently. General builders crayons work across multiple materials, but specialist formulations like tyre marking crayons are designed for specific surfaces and applications.

Colour Visibility: Choose colours that contrast with your working surfaces. Yellow and white provide excellent visibility on dark materials like steel, rubber, and dark timber. Black crayons work well on lighter surfaces such as concrete and pale woods.

Environmental Conditions: If you work outdoors or in wet conditions, select all-weather crayons that won't wash away or become unusable in damp environments. Indoor workshop users have more flexibility with standard formulations.

Pack Quantity: Professional crayons are frequently sold in packs of two or more at MyToolShed.co.uk. Consider buying multipacks if you use crayons regularly, as this represents better value and ensures you always have spares available.

Frequently Asked Questions

Will marking crayons work on wet or oily surfaces?
Professional marking crayons are specifically formulated to mark through light contamination including moisture, oil, and dirt. However, for best results on heavily contaminated surfaces, wipe away excess liquid or debris before marking. All-weather formulations offer superior performance in challenging conditions.

What's the difference between a marking crayon and a carpenter's pencil?
Marking crayons are wax-based and work on a much wider variety of surfaces including metal, glass, rubber, and rough concrete where pencils would fail. Carpenter's pencils are graphite-based and better suited for precise marking on timber and sheet materials. Many tradespeople carry both for different applications.

Can I use marking crayons in cold weather conditions?
Yes, quality marking crayons are designed to work in temperatures well below freezing. They're significantly more reliable than liquid markers or paint pens in cold conditions, making them ideal for outdoor construction and site work year-round.
