Our 16 year old pool is in need of resurfacing for the first time. I have made a few calls and people seem to have different approaches to the way they replaster. Some people tell me that they chip off all of the old plaster and give it a muriatic acid wash before plastering and some say that they just chip away the plaster from the tile and the light, etc and paint epoxy over the old plaster, then add new plaster. This is very expensive and I want to do it properly. Could anyone let me know the best way to have this done?

Thanks,
Lori
