Instead of replacing pool tiles that are showing wear and tear, a more economical solution is repainting the tiles. Three types of paint will work on pool tiles. Epoxy paint lasts the longest. It can be used on newly constructed pools as well as older pools that have been painted with epoxy paint before. It stands up to UV light, pool cleaners, and chemicals. Prepping the pool is the key to a successful paint job.
Drain the pool and take out all of the leaves and twigs.
Scrape the old paint off the tiles with a paint scraper. Use the power washer to get stubborn flakes off.
Caulk any cracks and allow to dry completely.
Scrub the dried pool with an acid wash.
Rinse the pool, using the garden hose.
Clean the pool with trisodium phosphate.
Pump out all of the extra water and allow the pool to dry for about five days.
Mix the paint with an electric drill and paddle mixer until well-mixed.
Paint the pool, using the roller. Start with the deep end and work toward the shallow end. Wait about five days before refilling the pool so that the paint can adhere properly.
