I am in the midst of finishing a portion of my basement. The previous owner had installed studded walls with no insulation on two of the four walls. The other two walls they used furring strips w/glue. I have since removed all of the old drywall and furring strips and installed new studded 2x4 walls. I also installed insulation, and read about a 6mil vapor barrier on the warm side of the wall, so I installed that over the insulation in part of the basement. I had only put up the vapor barrier in a small portion of the basement, and I have since put the project on hold for the last 4-5 months because of other projects. Last week I happened to notice major condensation between the plastic and the insulation. Now I am reading that I should not have a vapor barrier. I have since pulled down the vapor barrier and removed the insulation affected, and the wall behind shows no signs of water intrusion. The block walls were sanded and coated with multiple coats of Drylok before the studded walls were installed and the walls were bone dry to the touch, but warm.
I need to finish the project in the next couple of months, but am concerned about the condensation. It only happened in a 4x4 section, but I am wondering if I should put the vapor barrier up in the rest of the basement. If I keep up the vapor barrier and the condensation persists, will this cause future problems? Will it condensate on the new drywall without a vapor barrier? I don't know what to do!
There is not a huge problem with water in my basement, but I do run a dehumidifier.
Please help...I have a new delivery on the way in February and need to finish this project ASAP.
Thanks in advance to anyone that replies.
