Putting Copper Caps on Redwood 4x4's--Adhesive or Screws or Both
#11
  Re: (...)
I have several redwood 4x4's that need to be capped. Wife ordered solid copper pyramid caps but I am wondering whether I should seal them on the post with adhesive or just screw them on. I know that silicone is not friendly with copper but there are other adhesive options that I can use.

The question is whether the end grain will be better off by being sealed up or open so any condensation under the cap can dry out more easily. I am concerned especially because redwood is so sensitive to discoloration.

Any advice will be appreciated. Thanks,

David

My first choice would be a few dabs of Loctite PL Premium Construction Adhesive.
Any free advice given is worth double price paid.

silicone just a little to hold it on no further attachments

Copper nails would look better than screws.

I agree. There is almost no shear or tensile stress on the caps. A single nail will hold it in place with no problem unless someone goes at it with a pry bar.

These nails will look outstanding in that application: http://www.faeringdesigninc.com/fst-dec.html

If the raw copper is left to weather, all methods will do. With use of any mechanical fastener you will always run the risk of deformation of the copper and create a blemish. If a polished and lacquered finish is required or a blemish free installation is of upmost importance, the adhesive is the best choice. Any drilled hole to allow for a mechanical fastener will create finish problems.

Are these caps normally lacquered? Then as the lacquer wears or flakes off you will get spots of green. I'd sooner take some 00000 steel wool to them and remove all the lacquer and let it go all green like the Statue of Liberty. Very patriotic.



Seriously with natural redwood posts I would let the copper tops oxidize.

Nails come loose over time; screws can bugger up the copper cap, I like silicone or the construction adhesive of your choice.
