no, not really. but it's not a big concern, you can always chip it
off. but I'm just saying don't walk away after troweling some in
there. keep an eye on it for five minutes, and put it back if it sags
down and out. you will be doing multiple applications anyway, and if
you use the 20 minute mix, it goes fast.
once i get it troweled smooth, and sanded , is there anything else
needed to be done before i paint it?...
i apologize for all the questions, i just never had to repair anything
like this before and want to make sure i do it right
