Arrow Help: Cedar Post Installation

I'm putting in a 6' cedar privacy fence and have 4x4 cedar posts and read that your supposed to soak the part of the posts that are to be buried underground in a wood preservative. Does anyone know, is this any wood preservative like a typical wood deck sealer or is it something else?

Pentachlorophenol if you can get it. Otherwise, coppernapthenate. There are alot of brand names that have one or the other in it.

In order to get the amount of penetration necessary, the posts should be incised. The chemical should then be forced into the wood by pressure treating.

Unless you have already purchased the cedar posts, you might consider some of the steel post alternatives available. Check out Postmaster posts.

Wood posts, untreated, last about 10 years. Treating them will increase their life to about 12 to 15 years. Steel posts last about 50 to 100 years. How fond are you of digging post holes??
