Simple Instructions to Paint a Pool (DIY)

The idyllic appearance of your built-in pool, tropical blue or bright white, may have faded. As long as the water is in good condition, the cause of this dingy appearance is the finish of the pool on the sides and bottom.

The pools are constantly subjected to ultraviolet rays, chlorinated water and user activity. So it's no wonder that rubber-based pool paint lasts four to five years.

You can paint your pool in about a day or two. As with almost all other types of paint, the secret to long-lasting, beautiful results is preparation. If you drain and clean the pool properly, the paint application itself should be done very quickly.

The Best Pool Paint

One of the best types of pool paint to use is rubber pool paint. Because it is designed for swimming pools only, it adapts to the needs of swimming pools. It expands and contracts; resists mold, mildew and mildew; and is not affected by pool chemicals.

Rubber pool paint works well on new, unpainted pool surfaces. It is also ideal for painting over existing rubberized paint as old and new paint are chemically fused.

This paint cannot be used over previous epoxy or acrylic pool paint. It cannot be applied to fiberglass or vinyl-covered pool surfaces.

How Much Pool Paint to Use

Buy one gallon of paint for every 350 square feet of pool area.

Pool SizeGallons Needed
 12-foot by 24-foot 5
 15-foot by 30-foot 6
 20-foot by 40-foot 12

Recommended Conditions to Paint a Pool

Avoid painting your pool in direct sunlight. That is why it is better to paint in the morning. Paint during temperatures above 50 ° F and below 85 ° F. Surface must be completely dry. Also, do not paint if you expect precipitation in a day or two.

What You'll Need

Equipment / Tools

  • Roller frame
  • 3/8-inch lambskin roller cover
  • 3-1/2-inch paint brush
  • Nylon-bristle cleaning brush
  • Roller extension pole
  • Submersible pump
  • Discharge hose
  • Nylon rope
  • Pool brush
  • Shop vacuum
  • Tarp or sheet plastic
  • 5-in-1 tool


  • Rubber-based pool paint
  • Mineral spirits or paint thinner
  • Citrus based degreaser/cleaner


Drain pool

Plan ahead, as emptying the pool is a long process. Depending on the size of the pool, it can take up to 16 hours.

  1. Clean the pool by hand to remove large debris.
  2. Turn off the filter and unplug it from the pool.
  3. Connect the discharge hose to the submersible pump.
  4. Extend the free end of the discharge hose to a gutter, sanitary sewer, or area that can be irrigated with water of this quality.
  5. Lower the pump to the bottom of the pool with a nylon rope, making sure the pump rope extends out of the pool.
  6. Plug the pump into an outlet with a Ground Fault Interrupter (GFI).

Scrub Pool as Water Drains

As the pool drains, use the pool brush and extension bar to scrub the sides of the pool. You don't need to be constantly in the pool, but stay close.

Scrub and let debris fall into pool drain water. The submersible pump will discharge some of this debris, but expect to clean a lot of it manually in the end.

Scraped paint

With the pool dry, inspect the walls and bottom for peeling or peeling paint. Scrape with the 5-in-1 tool.

Clean pool

Sweep up debris from the bottom. Clean the pool with a citrus based degreaser / cleaner using the nylon bristle cleaning brush. Wash the sides with fresh water and pump the water. Do a final cleaning with the vacuum cleaner. Let the pool dry completely.

Get ready to paint

Attach the paint frame to the extension pole. Add the roll cover. Install yourself at the bottom of the pool, near the drain, with all the necessary tools. Cover the drain with a tarp or plastic wrap.

Cut in paint

Cut the edges with the brush. Borders can include:

  • Under bullnose
  • Up to tile coverage
  • Around the pool stairs
  • Around the drains
  • Even steps or bumps to be painted in a different color

Paint roller in the pool

Apply the rubber paint to the pool by rolling it up and down. Don't wear a thick coat. Instead, apply two thin coats. Applying a single thick coat can cause paint to fail. Do not thin the ink.

Work quickly and in small areas, keeping the tip wet. If an area is already drying, avoid painting over it, as this can cause marks and a rough texture.


Clean with mineral spirits or thinner.

Let the paint cure

Rubber pool paint does not cure by evaporation like water-based paints. This solvent-based paint can take up to 7 days to fully cure before you can refill the pool with water. Running large fans to ventilate the pool speeds up the drying process.
