The most important aspect of coating a pool is surface preparation. Your new coating will not adhere to even the slightest oily residue such as suntan lotion, body oils, hair spray, algae or anything that comes between the pool surface and the new coating. It turns the traditional 3-step surface preparation into and easy 1-step process. Simply mix PREP MAGIC with water, clean your surface and then rinse. See the Prep Magic Bulletin for more information.
