Can you paint the concrete shell instead of replastering your pool?

Painting a concrete pool shell instead of replastering is generally not a recommended or long-lasting solution. Here's why:

Adhesion Issues: Concrete pool shells are porous, and paint may not adhere well to the surface. Over time, the paint can chip, flake, or peel off, leading to an unsightly appearance and potential damage to the pool.

Durability: Paint is not as durable as pool plaster and is more susceptible to wear and tear from pool chemicals, UV rays, and water movement. The harsh pool environment can cause the paint to fade, discolor, or deteriorate rapidly.

Leakage and Damage: If the paint job is not done correctly or if the paint cracks or peels, water can seep through the cracks and cause damage to the concrete shell. This can lead to costly repairs or even structural issues with the pool.

Resurfacing Limitations: If you later decide to resurface the pool with a different material, paint can make it difficult for the new material to bond properly to the concrete surface. This can result in additional work and expense for removing the paint before resurfacing.

Health and Safety Concerns: Certain pool paints may contain harmful chemicals that can leach into the water and affect the quality and safety of the pool for swimming. It's essential to use paint specifically designed for swimming pools to avoid potential health risks.

Limited Aesthetic Options: Pool plaster offers a wider range of colors and finishes compared to paint, allowing for more customization and design flexibility. Paint may also not provide the same level of slip resistance as pool plaster, which is important for pool safety.

Overall, while painting a concrete pool shell might seem like a quick and inexpensive fix, it's generally not a sustainable solution and can lead to more significant issues down the road. Replastering the pool is typically the preferred option for achieving long-lasting results and maintaining the structural integrity and safety of the pool.
