My house is built on a cinder block foundation. On top of the cinder blocks, above the grade, the blocks have a skim coat of cement or something about 1/2 inch thick that is coming off in places. How do I fix this coating? What material is normally used? I assume in the loose spots I should pull it off back to the places with a firmly attached coating and in places where it is just cracked I should caulk.
Thanks in advance for the help…
Dave in NJ.

It's called parging, and here's an article that tells a bit about it.

Hey Cloud Hidden,
You a fan of Backwoodshome too?Excellence is its own reward!
I'm a fan of wherever I can find good work to learn from or admire, but I gotta admit to googling that one be/c I wasn't sure of all the spellings and mixes. I know how I've done it, and a coupla masons, but wasn't sure if that way was universal. What do you like about that magazine...I may have to look at it more.
There's quite an assortment of rags that deal with living out in the boonies or back on the edge, the stepchildren of the old Mother earth news... Some of them get a little weird. Back Woods Home is the most well balanced and reasonable and has some political editorializing that is very thought provoking. Their articles about how to... are more often written by somebody who has actually had some traning and experience which makes it down to earth instead of full of zealous DIY zombies giving each other bad advice. I hadn't ever been to their website until now so I've bookmarked the home link for them.

On houses with exposed cinder blocks I always ask my mason to parg the cinderblocks. He took mortar mix and covered the block.
First make sure the blocks are damp.Then mix type N mortar cement, sand and a little portland cement with water to where it will spread easliy. Take a trowel and spread the mix. Before it drys wipe it down with a damp sponge.
That give you a sandy finish. You can forget the portland cement if you use type S mortar
