1. Sand the rails of the ladder smooth with a nonmetallic abrasive such as
3M™ Scotchbrite® or softback sanding sponge. Do not use ordinary sandpaper or
emery cloth as it will leave atrace of abrasive grit embedded in the rail surface
and may cause the surface to be an electrical conductor.
2. Wash the entire rail surface clean with denatured alcohol or an equivalent
acceptable for health reasons and allow to air dry. Wash down a second time to
ensure that no residue is left on the surface of the ladder.
3. Use a primer followed by one or two coats of either acrylic lacquer or
polyurethane paint with U.V. additives for coating purposes. It is important to
coat the sawed ends of the rails whenever possible. To restore color, apply a
pigmented acrylic lacquer or polyurethane paint. Pigmented coating will screen
out an even greater amount of U.V. while restricting moisture entry.
Several acceptable coatings are on page five.
