I am asking for my husband who thinks this is a good idea (and I think it is a terrible idea)... Our pool is CLOSE to needing to be replastered. We are thinking about selling the whole property and hate to put money into real plaster and are afraid the "almost" state of the pool will severely hurt the sale. So he is thinking about a roll on plaster called Sider-Crete. If anyone has heard of it, could you give your opinions on it and on the general idea of a cheap quick do-it-yourself thing like this?
