Painting an in-ground pool is a time-consuming task but can be done by yourself with the right preparation. Firstly, you must identify the type of paint that was previously used on the pool, as you cannot paint over epoxy paint with rubber paint and vice versa. You must then drain the pool, which can be dangerous if done improperly, and clean the pool by removing any old paint, algae, dirt, leaves or debris. Once the pool is clean, you should identify any cracks or small holes and repair them with cement. You can then start painting, ensuring you follow the manufacturer's instructions for the paint you are using. The paint typically requires 7-14 days to cure before refilling the pool with water.

What You'll Learn
Preparing the pool surface
Firstly, identify the type of paint previously used on the pool surface. This is an essential step as you typically must repaint the pool with the same type of paint or an appropriate conversion product. To determine the previous paint type, you can perform a simple test. Rub the pool surface with a rag dampened with acetone for 30 seconds. If the surface becomes sticky, it is coated with chlorinated rubber; if not, it is an epoxy coating. Alternatively, chip off a small piece of paint and submerge it in isopropyl alcohol. If the paint does not dissolve, switch to a rubber-based solvent like Xylol or acetone. If the chip dissolves in the rubber-based solvent, the paint is rubber-based; if it doesn't dissolve, it is epoxy.
Once you've identified the previous paint type, it's time to remove the old paint and prepare the surface. Start by draining the pool completely, ensuring you follow proper procedures to avoid issues like the inground pool pop-up, which can cause cracks. After draining, use a scraper or putty knife to remove any peeling, flaking, or loose paint. If the previous paint has a glossy finish, lightly sand the surface with a sander to roughen it up. This will help the new paint adhere better. Use a pressure washer to clean the surface and remove any remaining dirt or debris. If you're dealing with a concrete pool surface, you can use muriatic acid to effectively remove the paint. Mix one cup of muriatic acid with one gallon of water, dip a bristled brush into the solution, and scrub the paint off. Remember to wear protective gear and follow safety precautions when handling muriatic acid. Rinse the surface with fresh water after cleaning.
The next step is to repair any structural damage, such as cracks or small holes. Use cement to patch up small cracks and follow the manufacturer's instructions for repairing the pool surface. If you have a powerful pump, ensure it is in good condition to help keep the water treated and clean. Look for any problem spots, such as scratches or areas where the paint has chipped away, and address them accordingly. Additionally, clean the pool filters to ensure a thorough cleaning of the pool.
Before applying the new paint, it is crucial to calculate the amount of paint you will need. Measure the length, width, and average depth of your pool, then use these values to calculate the total surface area to be painted. Compare this with the surface coverage per gallon indicated on the paint can to determine the required amount of paint.
By following these steps, you will have a properly prepared pool surface, which is essential for achieving a high-quality and long-lasting paint job.

Choosing the right paint
Once you've identified the previous paint type, you can choose the new paint. The three most common types are epoxy, acrylic, and rubber. Epoxy paint is the longest-lasting option, especially for bare, unpainted plaster, concrete, gunite, or fibreglass pools, with a lifespan of up to 8 years. For rough surfaces like bare concrete or gunite, a specific epoxy primer is recommended. Rubber paint is also durable and resistant to harsh chemicals, while acrylic paint has a shorter lifespan of around 2 years.
When selecting a colour, you can choose from a range of options, such as Blue Heaven, Ice Blue, and White, offered by brands like Leslie's Smart Seal collection.
Before purchasing the paint, calculate the amount you will need by measuring the length, width, and average depth of your pool. You can then use these measurements to calculate the total surface area and determine the required paint quantity. This step ensures you have enough paint to finish the job and avoid unnecessary waste.
Finally, consider the weather conditions and timing when painting your pool. Avoid painting during the hottest hours of the day, and ensure no rain is forecast for the next 48 hours. The ideal outdoor temperature for painting is between 50 and 85 degrees Fahrenheit. Spring is generally the best season for pool painting due to milder temperatures.

Draining the pool
Before you begin painting your in-ground pool, you must drain it. Draining your pool improperly can lead to what is called an "in-ground pool pop-up", where the ground beneath the pool rises, causing the pool to crack. Therefore, it is important to read up on how to drain your pool properly.
Firstly, make sure you are well-prepared before you begin draining. You should also confirm there will be no rain in the upcoming 48 hours and that the outdoor temperature is between 50 and 85 degrees Fahrenheit. Avoid painting during the hottest hours of the day.
Next, follow the specific instructions of your pool manual to drain the pool safely. It might take a few days to clean, seal and dry the pool.
Once your pool is drained, use a pool brush to scrub the surface clean. The old paint might be peeling or flaking, so scrape it off using a scraper. You can use a pressure washer to see if any remaining paint comes off. Remove any algae, dirt, leaves or debris from the pool's surface. During this step, you may also clean the pool filters.
Finally, look for any cracks or small holes that may have formed. Use cement for any small patches. Follow the manufacturer's instructions to repair the pool surface.

Applying the paint
Before applying the paint, ensure that you have calculated the amount of paint you will need. Measure the length, width, and average depth of your pool. Then, using these measurements, you can calculate the surface area of your pool. Next, refer to the pool paint can to find the surface coverage per gallon of paint. Finally, divide the surface area of your pool by the surface coverage per gallon to determine the number of gallons of paint required. It is recommended to round this value up to ensure you have enough paint.
When it comes to applying the paint, it is crucial to follow the specific instructions provided by the paint manufacturer. In general, the application process typically involves using a roller, brush, or sprayer to apply the paint evenly across the pool's surface. Start at the deep end and work your way towards the shallow end. Ensure that you follow the recommended drying times between coats, as specified by the paint manufacturer.
If you are using epoxy paint, it is essential to mix the epoxy components (Part A and Part B) thoroughly before application. Additionally, it is recommended to apply the first coat of epoxy paint within a day. After applying the first coat, allow it to cure for 24 hours before proceeding with the second coat. If you are unable to apply the second coat within this timeframe, you will need to abrade the pool surface again before recoating.
For rough surfaces, such as bare concrete or gunite, it is advisable to use a specific epoxy primer designed for such surfaces. This will help ensure better adhesion and a smoother finish. Additionally, if your pool has previously been painted with a different type of paint, such as chlorinated rubber paint, you must use the same type of paint for the new coat.
The weather conditions play a crucial role in the painting process. Avoid painting during the hottest hours of the day, and ensure that the outdoor temperature is between 50 and 85 degrees Fahrenheit. Check the weather forecast and ensure there will be no rain or strong winds during the application and drying process. Spring is typically the best time of year to paint your pool due to milder temperatures.

Drying and curing time
Before painting, the pool should be drained and the surface prepared, which includes removing loose paint, repairing any cracks or hollow spots, and acid washing the surface. After applying the first coat of epoxy pool paint, it is recommended to wait 24 hours before applying the second coat. The longer the pool is allowed to dry before filling it with water, the better the coating quality and longevity. For epoxy paint, it is recommended to wait at least seven days in summer and 14 days in winter before refilling the pool.
During the drying and curing process, it is important to monitor the weather conditions and keep the pool surface clean and dry. If rain or moisture comes into contact with the paint during this time, it is crucial to remove the water as soon as possible and allow for extra drying time. Leaves or insects that stick to the paint can be gently scraped away once the paint is dry.
Additionally, it is important to follow the manufacturer's instructions for the specific paint type used, as drying and curing times may vary slightly between different products. Adequate drying time is crucial to ensure the colour and quality of the paint job.
