I found this antique wood window and I plan to use it in a treehouse. What product should I use to: A) seal the wood and, B) preserve the 'chipped paint' look? Thank you so much for your help/time! D [ATTACH]77385[/ATTACH]

Building an 8x12 shed with wood siding panels. When I google things like pressure treated siding panel /t111 etc , at Home depot all I found were Out Of Stock things like: 19/32" thick PT T1-11: [url=http://www.homedepot.com/p/19-32-in-x-4-ft-x-8-ft-T1-11-4-in-On-Center-Pressure-Treated-Plywood-105595/100086683]19/32 in. x 4 ft. x 8 ft.

I think HD/Lowes is about %20 cheaper for similar products, and I read they can special ordered Out Of Stock items. This one is in stock but is only 0.375" thick but it's only $22 4x8, and is pre-primed and specifically says is good for sheds.

Cedar Fiber Panel Siding-25934 - The Home Depot[/url] I don't know what "5/50 Year Limited Warranty" means, maybe if it's painted right it will last at least 50 years, otherwise it's 5 years? I don't think it's pressure treated even though it say "Resists fungal decay and termites". But if painted with a thick amount of good paint and would last ~50 years, that's fine with me PT or not I don't care as long as it lasts. Usually there's a box in the Item's Specs that says Pressure Treated Yes/No, but that particular product doesn't have that box. These T1-11s that come up when googling Pressure treated T111, both say 'Pressure Treated' = "No". They're .56" thick but only the $40 pre primed one says 50 year warranty, the $30 unprimed has no warranty.

It doesn't say if I can attach it direct to studs without an OSB/plywood backer or blocking/bracing in the studs. But this one is only $28 and is 0.315" thick which is thinner than the $22 0.375" panel, but it does say this thinner one is "Strong enough to be nailed directly to stud, making additional sheathing unnecessary in many applications."

Strand Panel Siding-27874 - The Home Depot[/url] I'm leaning towards just using the 0.375" $22 panels, but I mean, shouldn't it be PT even if I'm going to paint it? Would it really make a difference if I spend double for thicker and PT panels that aren't even primed. Since the cheaper boards are thin, should I put horizontal blocking between all the wall studs for bracing even though it says 'strong enough to use direct to studs without additional sheathing'? That's pretty much all I found on HD site. I will check Lowes also but it seems to be the same situation. Actually just found this $28 panel which is PT and pre primed and 'strong enough for direct to studs" [url]https://www.lowes.com/pd/SmartSide-38-Series-Primed-Engineered-Treated-Wood-Siding-Panel-Common-0-375-in-x-48-in-x-96-in-Actual-0-315-in-x-48-563-in-x-95-875-in/3058153[/url] I guess I answered by own question but seeing if the thickness matters so much (if should still block between studs and if thinner panels will rot out faster). And also, the $22 and $28 home depot boards might also be PT like the $28 lowes one even though they don't say it, I can find out. ----------------------------------- One last thing, I didn't really calculate this at all but I'm guessing vinyl siding would be ~%50 more than wood, but what about possibly needing to repaint the wood? I mean, our house is only painted once maybe every 20 years (45 year old house) and looks fine. I think the wood parts are cedar shingles which are protected from soffits but the rest without soffit protection is cement panels that paint still looks fine on. Estimated cost for Vinyl $700: $150 OSB behind vinyl including gables. 12x8 shed 7 foot high walls. $12 a board x 12 boards $75 tyvek over the OSB. $300 vinyl siding (about $10 per 12' X 10" piece) Meaning roughly 8 pieces per 12 foot side of shed is $160 for the two 12 foot sides. And including the gables on the two shorter 8 foot sides is about another $140 ~$ 60 for the 4 vinyl siding outside corners. ~$75 J channel and starter strip. and then it would look tacky if I didn't cap the fascia with white aluminum trim which would add on another ~ $60 but I might just omit that and just paint the fascia. ~55 vinyl soffit --- VS. Wood estimate (and less work): $450 ~$300 $25 per panel pre primed x 12 panels. ~ $30 1"x3" PT as the outside corners ~$10 soffit vents, the soffits I would make free from the 1' scrap rips from the walls being 7' made from 8' panels. ~$120 for paint? ~360 sq foot needs to be painted includes soffits and gables. The ~$25 pre primed composite panel manufacturer recommends Acrylic Latex paint. I assume semi gloss would be preferred which I see with some paints almost doubles the price vs their satin finish. I'm not sure if I should do two coats or if one thick coat is enough. I'm not sure which paint to use. What if I used that deck restore paint that fills in the rough surface of the panels well? Can you link me some good choices for paints from home depot/lowes? Just eye balling it from experience, I would think 3 gallons would do one coat for a 12x8 x 7 foot high shed with rough surface panels but I'm not sure. I mean I'm seeing gallons of exterior acrylic latex claiming to cover up to 400 sq ft, but even if my siding panels were smooth surface, I highly doubt 1 gallon would do 1 coat for the entire shed. And then, no I don't have to worry about painting it like every 5 years right, with the right paint, it should last about 20 years? There's going to also be a gable lookout framed about 1' overhang so at least most straight-down rain won't even hit the siding on the gable sides but most rain isn't straight-down, but still gives some protection.
