3. Ladders stored out-of-doors for extended periods of time can have the effect of
weathering decreased by semi-annual waxing of the rails. Normally a good
commercial non-slip paste wax, such as Trewax3, clear paste wax, will reduce
the possibility of glass fiber prominence.
4. Ladders employed in geographic locales with high U.V. ray exposure can have
extended life and reduced potential for glass fiber prominence by periodic coating
with certain acrylic lacquers, polyurethane coatings or similar materials. The
U.V. additive employed in the resin formulation is gradually consumed during
sunlight exposure. These subsequent coatings replace the U.V. screen or barrier.
5. A spot coating with a highly pigmented polyurethane resin is highly recommended
when the ladder surface has been damaged by localized impact or abrasion. If
there is any structural damage consult Werner Co. on repair or replacement
or discard the ladder.
6. Ladders in service out-of-doors, where high humidity or high humidity coupled
with intense U.V. ray exposure exists, may have their service life increased by
applying a lacquer or paint coating and waxing.
