Shingles could you tell me the finish on the inside (underwater) portion of your pool? Do you know if this type of finish could be placed on an old pool in place of plaster? We will be needing to restore our plaster after last summers bout with black algae and constant brushing with the wire brush. I really like that darker finish. Is it as strong as plaster—should we have to brush with wire brushes again?
