wet insulation
Guys, I'm having a dreadful time. I'm building a new kennel, part of it is cement block and part is stick built. The stick is where I'm experiencing moisture in the walls. The out side is metal with Tyveck over OBS board. Now here is where I made my mistake. The walls are 2x6 and I put in R19 fiberglass backed insulation. After thinking about this I decided to put another layer of R19 over the original. I did not remove the paper from the original layer. I was worried about moisture in the wall so I read that I should cover the entire thing with plastic. When my son came today to apply the paneling to the walls we discovered that mold had started to form on the OSB board between the insulation and the interior of the OSB . We plan to pull away the insulation and spray down the OSB with bleach to kill the mold and also peel away the inside layer of paper.
The wall is only 2 months old, can't believe this happened so fast. Will doing what I described cure the problem? Should I remove the plastic? How do I prevent moisture from building up? What's a guy gonna do.

Thanks for the feedback. Taking of the OSB at this point is not an option the building is 55x20, lot of steel and board. Too costly at this point. I was worried about the steel siding, but was hoping the Tyvak would prevent problems. I am thinking of puling of the insulation, spraying with vinager solution and puting in on a new layer of r19 foil backed and then applying sheeting. What do you think Look forward to any help.

OK, I do not have the interior board installed yet, just the insulation (2 layers) and then OSB then Tyvak and then steel. I was planing to take out the insulation exposing the OSB, spray with vineger and let dry and see what happens. It's easy to say to rip everytrhing out, however that is a lot of money to spend if I don't have to. There seems to be mold in a couple of places in the entire wall. I'm just sick about this.

OK, please understand there are no interior boards. It's steel, tyvak,OSB, insulation batts with vapor barrior. The mold is on the warm side of the OSB. I agree by using the double layer of inulation and not removing the vapor barrier on the first or cold side layer I trapped moisture in the walls. The wet is in a few spots not the entire wall.. I'm pulling the insulation down and letting the OSB dry out before spraying vineger. I am also thinking about having a 1" layer of foam sprayed over the OSB to stop the mold. I know spend now or spend later, easy to say but I don't have the money to spend now.

Well I pulled out more insulation and the problem is everywhere some a little some worse. Only good thing is its white mold not the blsck stuff. I'm have a foam insulator comeing over to give me a price on foam. I understand that will seal off any mold that is trapped in the wood and prevent anymore contact with warm to cold.

Well I just got a quote form Sunrise Insulators over in Dundee for 2200. This is for 3" of foam, gaurenteed to stop further moisture problem and prevent any air flow into the walls. The only down side is I will have to scrape all the material that I have put in so far. Throw away 2000 and spend another 2000 grand plus.

Yup, I'm with you on that, Bagged uo the stuff and put upstairs for future install. I started to remove some paneling that I had started,wanted to look and see how bad that was, it's wet as well, I will be able to reuse it as it came off pretty easy, just had to slice it along the top edge because the drop cieling is in place at that location.
Thanks to everyone for the help.
