copper-brown

[fred1949]

Can anyone tell me their experience with a product called Copper-Brown or Copper-Clear? I have some rot occuring on some cedar decking. Also can you tell me which is better for exterior use cedar or wolmanized lumber?

Well, one thing I can tell you is that composite decking is the way to go, but if you are set on wood then I would go with the pressure treated wood. I have a cedar deck and have replaced lots of boards due to rot. Cedar is naturally rot resistant, but it will definatly rot and that's even with a good sealer, especially on the cut ends of the boards. PT won't rot out like this and is way less expensive, just that you need to install it right away when wet or it may warp when it dries if it's not screwed down.
