So I used the Henry’s floor patch and level. It’s cementious and give you a feather edge up to and inch if you have time for coat build up.
I may have overreacted about it. I didn’t mind it at all.
The whole point of feather edges should be just that but when you use cement based fillers the pumice leaves a raised grit opposed to a softer to the touch filler.
Bottom line is if you have to come back and sand anyway then it won’t matter.
