There are three different types of swimming pool paint you could buy: Epoxy, Acrylic, or Rubber Based.
Epoxy swimming pool paints are typically the most durable and suitable for swimming pool applications. Epoxy paints are commonly referred to as "Marine Paint". This type of paint includes 2 parts, the resin and hardener. Most epoxies mix at a rate of one to one to form a resin. Over time, epoxy film with become chalky over time.
The other main type of swimming pool paint is
Acrylic Swimming Pool Paint and does not require a hardener or catalyst system like an epoxy paint does. The paint is a polymer resin, but a lot of pool paints are water based. This means that the paint is suspended in water, not oil. Therefore, it's a lot easier for the homeowner to apply since the fumes are not as strong as they would be with an oil based paint.
It is a lot of work to paint a swimming pool, so first decide if you really want to put in the effort. Sometimes, you could just get away with a good cleaning. You may want to consider an acid wash if your current coating can handle the cleaning.
As with any paint job, preparation is probably 99% of the key to success. First, make sure the type of paint you choose can be applied over your existing paint. Not all paints are compatible. The paint could wrinkle or lift due to the chemical reaction.
Once you've selected the color and type of pool paint, epoxy, or acrylic, it's time to drain the pool and take out any obstructions.
Scrape or sand off any flaking or peeling paint and and feather the edges.
Make any repairs to cracks or anything with your choice of caulk, cement, or other products.
Read the manufacturers label for the pool paint you're using to ensure you use compatible chemicals and materials.
Clean the pool with an muriatic acid solution or per your pool paint instructions.
Rinse the acid off and clean with trisodium-phosphate, TSP.
Final rinse the pool with clean water.
It is best to pump all the water our and thoroughly let the pool dry. Blow out any water that could run out of your skimmer, drains, etc.
Some paints require a primer coat, some are self priming, so read your paint instructions.
Most paints are applied with a standard NAP roller. You probably want to buy an extension to make the rolling easier. Use a brush for corners and hard to reach areas. Start in the middle and work our way to the corners (Just Kidding)... start in the deep end and work your way out of the shallow end.
Wait a few days, longer for some paints, before filling your pool back up with water.
