Drying Pressure Treated Wood
 
I have two lengths of 2 by 10 by 7 foot ptw stacked flat on sticks in my shed. The shed can get hot even with the doors and windows opened. I have them in there to quicken the drying process.
Is this a mistake?

It won’t be a mistake.

Thanks,
I should have done a bit more research in picking the right type of wood for a fascia that is under a soffit. I seen recommendations for southern pine, fir and I level framer series which may be the best choice. Whatever gets installed will be primed and painted and then capped with aluminum. I just want something that will be trouble free.
I am installing a retractable awning next Spring and according to the distributors recommendations, I will need 2 by 10 lumber to mount the brackets.
Back in 1980's, I had a deck built with ptw and all the deck boards cupped and I ended up replacing them about 15 years later. There was one short piece of 2 by 12 attached at a 45 degree angle to two beams that was actually falling apart. I do not think that wood was properly treated either by the manufacturer or by the lack of proper maintenance by me.

Return that wood and get standard /untreated wood.

The chemical in the ACQ treated wood will corrode the aluminum wrap very quickly.

Read the big letters on the outside of the box on any aluminum coil stock.
DO NOT APPLY OVER PRESSURE TREATED WOOD.

Thanks Mike & Joe,
I also learned that too through researching the net.

:(Joe and I have seen the results and had to fix them---:laughing:

If you can afford it, you might think of something other than pine or fir. Redwood or cedar might be less prone to cupping.

When you say "under a soffit" do you mean the frieze board located under the soffit? fascia board is the board that the gutters hang off of, frieze board is under the soffit on the exterior wall and butts up to the soffit at inside corner of soffit...

<frieze board is under the soffit on the exterior wall and butts up to the soffit at inside corner of soffit..>

Yes, then I misnamed it

joe is very right.. aluminum cladding thats in contact with pressure treated will literally turn to ash

the first time i saw it was on a sun room that was sheathed with pressure treated plywood then clad.. we had to strip all the old aluminum off, the cover the pt plywood with blueskin so the chemcials wouldnt leach through .then reclad

Thanks all,
I had to settle for hem fir for my 2 by 10. I priced cedar and was quoted $80.00 for a 16 foot length. The hem fir was $20.00 for a 14 foot length. I have it in my shed to dry. Recent wind blown rains got it wet.

oh'mike 08-24-2013 06:42 AM

You will be fine------odd that the original one rotted out----

rjordan393 08-24-2013 07:20 AM

The original is fine. The 2 by 10 will be secured over it. The reason is: The brackets for the retractable awning are too big for the original frieze and require a 2 by 10 to mount them. There is no wall under the frieze. Its an open area with just a roof covering a patio.

oh'mike 08-24-2013 07:24 AM

Good--then you will be just fine-----good luck and post a picture when you are finished---Mike----
