High Performance Epoxy Pool Paint is designed for concrete, masonry, steel, gunite, and fiberglass swimming pools, slides, fountains and spas. The epoxy finish provides stain, chemical, and abrasion resistance. While exposure to sunlight and certain interior lighting conditions causes fading and chalking of all epoxy type coatings, these changes are cosmetic in nature only and film integrity and performance will not be adversely affected. Epoxy coatings will yellow with age. This is most noticeable with interior applications of white or light colors which are not subjected to bleaching from sunlight
