Hello, I'm new to this forum. I wish I had joined earlier to avoid problems with my plaster. I have stains, scaling and a nasty crack on a corner. I'm going to replaster either later this summer or at the beginning of next year. I've gotten 12 years out of the original plaster and was fine until last year when I used too much and the wrong algaecide. I thought I might try to sand a few bad areas to buy some time and enjoy the upcoming holidays. Any tips on sanding would be much appreciated. Grit, hand vs power etc.
. Pool is almost drained. There is a small pond in the deep end I need a shallow pump to get out. I power washed everywhere else and tried some 80 grit on a hand sanding block. The scales and stain seem to come off fairly easy, surface is much smoother too. I think I'll try to sand it myself tomorrow. It's a big pool but I'm hoping to do it 4 hours and then fill it. My big question now is I have that crack I need to seal. I bought some silicone sealer but when I was about to put it on I noticed the product is not meant for submerged conditions. Any ideas on a good crack sealer that can hold up to water? The crack runs from the coping down into the pool about 12".
