As swimming pools age, they can become cracked and tarnished due to excessive weather and water exposure. Fortunately, you can renew the look of your swimming pool by adding a fresh coat of paint. However, before you slap a coat on your pool, you'll have to work to promote adhesion. It doesn't matter if your pool is bare concrete or if it has previously been painted with an epoxy coating, you need to know the specific techniques that encourage paint adhesion or you will end up with chipping over time.

  1. 1

    After fully draining the pool, abrade the surface of the pool to promote adhesion by applying muriatic acid. Apply the acid using the spray nozzle included within your kit. Follow all the safety instructions printed on your specific kit.

  2. 2

    Allow the acid to sit for 10 minutes. Rinse the acid according to the instructions on your specific kit. Allow the surface to dry completely before continuing.

  3. 3

    Pour the chlorinated rubber paint into the 5-gallon bucket. Fill it just about halfway. Attach the nap cover to the roller frame and attach the frame to the extension pole.

  4. 4

    Apply the chlorinated rubber paint to the surface of the pool using the roller. Apply the paint to any areas inaccessible to the roller using the 4-inch latex paintbrush.

  5. 5

    Allow the surface to dry for three hours. Apply another coat if necessary.

Tips and warnings

  • Never attempt to paint a swimming pool in temperatures below 10 degrees C.
  • Never use muriatic acid on a plastic or vinyl swimming pool.
  • Muriatic acid etching kits can differ greatly from one to another. Consult your specific muriatic acid etching kit for exact safety and application instructions.
