HOW ARE PRESERVATIVES APPLIED IN THE FIELD?
Liquid preservatives can be brushed on the cut end, or the end can be dipped into them. Spraying is not recommended. If dipping is used, a minimum of three minutes immersion is recommended. If brushing, use two coats. Only the cut end need be dipped or brushed. Workers should wear proper protective gear (rubber gloves and eye protection) when using these preservatives, primarily because of the organic solvent. Borate rods and pastes are inserted into pre-drilled holes and plugged tightly with a piece of dowel, a plastic plug or some other suitable material to keep water out of the hole.
