Peeling and blistering paint is indicative of defective paint. If you are attempting to repaint the pool, all of the defective paint should be removed or the problem will not be solved. As a temporary measure, you can sand and scrape the affected areas. Be sure to repaint using the same kind of paint that was last used. To solve the problem on a permanent basis, you must drain the pool and sand blast the pool to completely remove the old paint.
