i have a jacuzzi, 1,600 gallons and we had it replastered 5 years ago and now there are some spots where the plaster has come off. My question is, I've seen ads for the "do it yourself" plaster things and I was wondering how good these work? Just need to fill in a few spots.
Also, if these work good, does the concrete have to be completely dry for me to patch the plaster in?
Anyone have any experience with these?
