In my “cold room” where the water pump, sump pump and water filter is located, I’m getting condensation on the concrete ceiling, which is also the floor of the front porch. This only happens in cold weather. There had been a moldy, rotten piece of plywood there, probably left from forming the slab ceiling/floor, of which I removed. I’ve had a floor fan directed out of that room all winter, but am still getting condensation.

I’m considering using Nansulate thermal barrier paint. What do you think of this solution?

Thanks!
