I had my exterior foundation block wall re-parged, first they applied a mesh wire then a layer of hand mixed water proof cement and then a hand mixed coat of parge consisting of concrete & sand. The problem is the entire foundation is spider web cracking from the bottom up. How can this be repaired? Or is there a crack sealer/paint to fill in the excessive cracking? It's only been four months since this job was done.

We call this application stucco and I have not personally done one. However it sounds like they may have used too much water. In any case, you should have more than 4 months warranty from the installer. I would make him come back and assess the problem.

There is no warranty & no installer. We had a large new additions construction job and the contractor along with his subs walked off the job and left us with a mess. Not Even FUNNY! The parge job is a cracked up mess and the color is really blotchy. Our new garage floor is all cracked up too.

Bad portland cement or at least a bad mix. The floor is probably going to be strong enough, all concrete cracks to some extent. If you are totally on your own I'd try a Stucco paint or sealer. It is thick enough the fill and bridge the cracks.
