Brian from Gisborne New Zealand writes
The timber is kiln dried and I don't want to increase the moisture content.
BORACARE must be applied in a diluted fashion with water to work correctly and absorb into the wood. Boracare and the glycols it contains are designed to replace the natural moisture content of the wood so it bonds and last long term in the piece of timber you are trying to protect. Nisus, the manufacturer of Boracare, states that Boracare can be applied to kiln dried wood or prior to being placed in a kiln.
