Gotcha. So if I were to do this smartly, I’d treat the framing lumber for mold, then replace all of the roof and wall sheathing to fresh OSB. Then seal and insulate walls? Concrete floor goes in in the spring.

 

get a moisture meter , check the moisture content of the lumber and plywood , over 24% (IIRC) will harbour mould

 

If it were me first I would verify 100% the water is not coming in from outside, then I would run a dehumidifier in there for a couple weeks to dry everything out. Then, after verifying the wood is structurally sound and at appropriate moisture levels like oz said I would give it a quick scrub (respirator on lol) then cover every envelope/condensing surface aka sheathing with some of this. https://tigerfoam.com/sprayfoaminsu...er-foam-slow-rise-formula-600-board-foot-kit/. Thickness of foam based on climate
In the meanwhile I’d consider putting a temporary vapor barrier down on the floor to be replaced by the one that will go under your slab

What kind of cladding is on outside of shed?

 

Doesn't appear to be sealed to the point that a dehumidifier would work to suck moisture out of the boards.

Moisture meter it, if its not overly damp, spray everything with a mold killer/inhibitor and call it a day. Get to work sealing the thing off, ridge vent, pour the slab, get your doors in so its all sealed off and then insulate and sheeth the inside.
Its a shop in an old barn, it's not going to look like Oz's with brand new lumber.

 

Does condensation forms on the tank from the heat, from the baseboard?

It's not the septic smell that you have to worry about.

 

Lol good point about it being too open for a dehuey to do much good
As a matter of fact kinda difficult to imagine such a drafty building with (I’m assuming) no heat source being able to create a temp/humidity gradient that would allow condensation in the first place.
I bet it’s liquid intrusion either thru sheet flow (crack in roof sheathing) or capillary action (area above door)

 

Or its just old weathered lumber thats been covered but still "outside" if you will. Lumber looks fine to me. Then again I can't smack it with a hammer to know for sure.

 

This is concerning, looks like fuzzy moldy active rot
But then wtf is that string looking thing coming down into it lol

I agree. A hammer test is in order

 

Those are sure some nice expensive bike tools you have hanging there!

 

Never have had condensation issues do far.

 

Oh those are remnants of old insulation someone ripped out. Definitely isn’t any fuzzy mold going on in there Thanks for the vote on confidence on everything though! I’m in the northwest so who knows what got in there. The framing stands up to a nice smack with the hammer, but it’s not sealed whatsoever. Literally there’s a 1 ft gap between the stable doors and the roof. So it’s virtually been outside under an awning for 45 years. I’ll moisture meter it and try to get my floor poured asap. Not a bad idea to do a dehumidifier when the floor gets poured and I seal with doors.

 

if it was insulated with batt insulation with no air channel above to move moisture that would trap any condensation against the roof sheathing and rafters , that could have be the problem right there

 

You know what I always say: fuck plumbers and electricians

 

They soak their boots in vinegar......to keep the ants from crawling up to their candy asses.

Biggest bunch of whiners of all the trades.

 

You should meet the countertop guy I just had to deal with on our most current addition.

Old tops in the kitchen where tiled. After removing the tile and wire the sub top was still in really good condition. We decided to use it as it would be fine for the new Cambria quartz top.

Countertop guy shows up to get his numbers. He looks at the sub top and sees a few hundred staples from the old wire. These are standard T50 staples. He looks at me and tells me those staples need to be removed.

I start laughing at this joke. Then I look at him and he's serious. This forces me to laugh even harder. Like that deep gutteral laugh that actual starts to hurt after a minute. Yep, I was laughing that hard in this poor guys face.

I honestly think he thought those staples could support a 250Lb countertop without getting flattened. They can't and I let him know if he needed then removed he should start that process because I wouldn't.

He left without saying another word. The staples where still there. lol

 

Looking for an opinion on some concrete. A couple years ago I read somewhere about intentionally mixing concrete with sand, cement, water but not nearly enough cement. The intent of this mixture is to keep the sand from moving and eroding away. Once of the bonuses is that it can be chipped away without much effort. I tried this in the back of my house and it's held up for a couple years now. Obviously it doesn't have the strength of proper concrete.

What are your thoughts on this? Is this actually used commercially anywhere?

 

I get condensation is bad on the tank. It look like someone pee all over the floor.

 

If you are talking about a sand tamped patio or pavers there is a polymeric/silica sand/additive that you can use as a binder. You use it as a finish course and then wet it down to activate the polymer/silica. It’s spendy though.

 

yes, like that but even less cement. When it's fully cured, it very brittle compared to mortar.
