How To Paint A Gunite Swimming Pool

Resurfacing and Repairs AKA Painting and Pools


If you own a gunite swimming pool, you may have noticed that the surface has become dull and stained over time. Fortunately, painting your pool can give it a fresh new look and protect it from further damage. In this article, we will guide you through the process of painting a gunite swimming pool.

Choosing the Right Paint

Before you begin, you need to choose the right paint for your pool. Epoxy and rubber-based paints are both good options, but epoxy is more durable and long-lasting. It is also resistant to chemicals and UV rays, making it a popular choice for pool owners.

Preparing the Surface

To ensure that the paint adheres properly, you need to prepare the surface of the pool. Start by draining the pool and letting it dry completely. Then, use a pressure washer to remove any dirt, debris, or algae from the surface. You may also need to use a wire brush or sandpaper to remove any stubborn stains.

Repairing Cracks and Chips

If your pool has any cracks or chips, you need to repair them before you can paint. Use a pool patching compound to fill in any cracks or chips, and let it dry completely before sanding it down. You may need to repeat this process several times to achieve a smooth surface.

Masking and Priming

Before you can paint, you need to mask off any areas that you don’t want to paint, such as the tile or coping. Then, apply a primer to the surface of the pool. This will help the paint adhere better and last longer.

Painting the Pool

Once the primer is dry, you can begin painting the pool. Use a roller or sprayer to apply the paint in even coats, taking care not to overlap or leave any streaks. You may need to apply multiple coats to achieve the desired color and finish.

Drying and Curing

After you have finished painting, you need to let the pool dry and cure for at least 72 hours. During this time, you should avoid filling the pool with water or exposing it to extreme heat or cold.

Maintaining the Paint

To keep your newly painted pool looking its best, you need to maintain it properly. Use a pool brush or vacuum to remove any debris from the surface, and avoid using abrasive cleaners or tools that could damage the paint.


Painting a gunite swimming pool may seem like a daunting task, but with the right tools and techniques, it can be a rewarding DIY project. By following these steps, you can give your pool a fresh new look and protect it from further damage.
