My woodworking has taken a slight detour as I am building a shed in my back yard. It is 10'x12' so I can have more room in my garage for my woodworking, and perhaps a car if I can squeeze one in.
On the shed, I may have made a mistake by applying pressure treated wood for my fascia boards. Too late, it is done. My problem is that now I need to wrap the fascia with aluminum, which I have learned is not a good idea due to the copper in the PT lumber does not play well with aluminum.
Now for my question, if I apply shellac to the PT, will that be an effective barrier to protect the aluminum? I was also considering using some roofing felt paper that I have remaining. If I had a 'do-over', I would not have used the PT, but like I said, that ship has sailed.
I appreciate your comments.
