Skimmed over some sand and cement today, trowel, trowel as normal for me. Got it all sorted n finished. Went back into the room to clear up after doing some patching and there were lots of little pits on the surface that werent there when i left it. Any ideas whats caused this?
The sand and cement was well and truly set having been done years ago when the fireplace was bricked up. I prepped as normal with 2 coats pva and skimmed over it when dry.
