When deciding to paint your pool with Smart Seal, you can choose from several options. On bare surfaces like plaster or bare concrete, Smart Seal recommends the epoxy Dura Seal system. The advantage is longer life and greater value. Dura Seal is also recommended for sandblasted or fiberglass surfaces. SR Pro 7 synthetic rubber-base and Aqua Seal acrylic-base are also excellent choices and can be applied to bare plaster or concrete surfaces (not sandblasted or fiberglass), or surfaces previously painted with a rubber-base or acrylic formula.
If your pool has been previously coated, it is important to determine the type coating on the pool so your new coating will be chemically compatible. The best way to determine your existing coating is take a chip to your local Leslie’s store and they will “test’ the chip for identification.
Or, you can send a chip, preferably 1”x 1”, to the Smart Seal manufacturer and they will call and advise you. To field test yourself:
Prepping a pool: Surface preparation is the single most important aspect of coating or re-coating a swimming pool. On re-coats, all grease, dirt, lotions, oils, and mineral deposits must be removed so the new coating can chemically bond to the existing coating. For bare surfaces, it’s necessary to mildly acid wash the surface to remove mineral deposits and microscopically add porosity to the surface.
The simplest way to achieve this is by using Smart Seal’s PREP WISE a pre-packaged solution that simply mixes with water and performs the three steps of oil, dirt removal, acid etching to remove minerals, and neutralization of and acid residue. Or, you can perform your own three steps using tri-sodium phosphate, muriatic acids, and tr-sodium phosphate again. Obviously the more simple and very effective method is one-step PREP WISE.
