Check into the treating.O.K. I've heard it before... If you cover treated wood with coil it causes a chemical reaction that will:
1. cause corrosion on the coil or
2. cause the treated wood to rot
I'll be honest, if a homeowner wants me to wrap the treated 4x4 posts on the porch, I'll do it.:thumbsup: I will warn about the possible outcomes and offer the solutions of wrapping posts with tyvec or changing out the 4x with two untreated 2x4s. However some of the time I get that look that says "You are just trying to pad the bottom line by adding unnecessary labor/materials"
In those cases I'll let them decide and be sure to waive any warrantee on anything installed against manufactured recc. :no:
What gets me is I have never been called back to any of these projects to repair any corroded coil and seriously doubt that there has been much damage to the post.
Maybe not enough time has passed for the process to take place,:001_unsure: Or maybe it is just a pitch to sell more tyvec. Either way I try to cover my ar$$ when the situation comes up.
My latest run in with the old wood/metal/chemical reaction triangle has a new twist on it though.
Building is brick and block cmu. The plan is to strip out with treated 2x4 and cover with metal siding. My supplier tells me that I'll have to use stainless steel self tappers to fasten it or it will be falling off in a year. OR
furr it out with hat channel. Either way is going to add good bit more to the expense.
I dont know...my boosh hit meter started tinging. I'd love to hear some thoughts on the matter.:notworthy
It's all over the place again.
The new micro pro treating is
less corrosive, and mostly all
one can find here.
Also depends on the siding,
Steel, or aluminum?
Either one would want to be
powder coated on the contact side
at the least.
Find out about the treating,
and do your research on the
