Ok so I have attached a 2 sided massive tarp to my house and then added tarps around the sides to create walls. It's built over my back porch and a concrete patio with some ground showing and some ground covered with pallets. Needed a workshop so this is my alternative. Did this at my other house and didn't have this problem as much but also had I think 2 for sure but maybe 3 tarps as the ceiling. I have a propane heater, an electric heater, a regular household standing fan and a big stand up shop fan. And a hole for ventilation but maybe it's not big enough or something.
This tarp is like raining on the inside is the best way to describe it. Right directly above the heater is ok but the rest of it is a downpour. I have the tarp sloping downward from the house but I'm at a loss on how to stop all of this condensation. Anyone with more knowledge about this?
I have tried not using the propane heater but that made things worse. Like when it's raining. Electric heaters may answer the question just hate what it will do to the power bill.
