What type of paint or coating is allowed on a wooden ladder?

• A. Oil-based paint
• B. Water-based paint
• C. Transparent coating
• D. Gloss enamel

Answer: (C)

Coating a wooden ladder should protect the wood while letting you clearly see its condition and keep the surface safe to grip. A transparent coating does just that: it forms a protective layer without hiding cracks, splits, or rot, so you can inspect the ladder easily and catch problems early. It also protects against moisture and wear without drastically changing the surface texture or appearance.

Oil-based or water-based paints and gloss enamels add color and often create smoother or glossier surfaces, which can increase slip risk, especially on rungs that need good traction. They also can obscure any existing damage, making inspection harder. A transparent coating, especially in a non-slip, matte or satin finish, provides protection while preserving visibility of the wood and maintaining grip.
