I have a concrete block wall in my basement that is chronically damp inside. I had a contractor over to look at the situation - whether the outside of the wall should be resurfaced, etc. - and he thought parging the concrete block before finishing the wall, would be enough. He said a layer about 1/8" thick. He said they use a compound with fibers in it.
THe coat couldn't be thicker than 1/8" because there's a staircase going down alongside the wall, so space is limited. The parging would be for waterproofing, not for cosmetics. It can be rough, because I'm building a wall over it.
Is this a reasonable job to do oneself? With what kinds of tools? What kind of cement should one use for waterproofing?
