T HE WATERITORNE Pressure

I treatment of wood, fronr a western standpoint. is an operation that contains variables and challenges rhal maY not be recognized by people [rom our southern nrarket areas. Instead of dealing with one basic species grouP (southern yellow pine) that is probably the easiest to treat. western operators are faced with several different types of wood.

The mosl commoil ones include the pines, Douglas fir' hem-fir. weslern larch, redwood, cedar' lnd Sitka spruce.

The group classified as hem-fir is made up of six seParate sPecies: western hemlock, Pacific silver {rr, noble fir, grand fir, California red fir and white fir. Each one of these species has its own treating chitracteristics, and that has probably been the cause of manY sPirited discussions between a Plant manager and his treating engineer over the years. It is largely in response to that problem that several tYPes of walerborne preservatives are used in our western plants.

In the pressure treating of wood products, it is necessary to achieve both a proper Penetration of the solution into the member as well as a retention strong enough to be

CIZC has proven to be a good preservalive Ior use in drier applications. Because it is subject to leaching under wet conditions. it is not recommended for ground contact or in wet installations. It will meet AWPA and AWPB standards for above ground use

All of the waterborne Preservatives mentioned he re leave the wood surface comparativelY clean, paintable. and free from odor after drying following treatment.

Species containing large amounts of heartwood, such as Douglas fir and hem-fir, are usually' incised with small perforations in order to form passages for the preservative lo penetrate deeper into the wood.

To a large extent, it is because of the differences of the western woods in terms of their heartwood and sapwood content that several types of chemical formulations

Although this has been onlY a cursory look at waterborne treating in the west. I hope it has brought to your atrention some of the different species and solutions that are used lrere. Along with creating more variables to contend with, this variety also presents opportunities for the consumer to choose results in regards to cost, color after treatnlent, and degree ol protection needed.
