Painting a damaged pool deck is not recommended if the substrate is crumbling, cracking, spalling, or otherwise actively deteriorating. Continuing deterioration will result in the paint also delaminating or flaking off the damaged surface. Minor damage such as chips or hairline cracks that are not actively deteriorating can often be repaired enough to paint over. A damaged pool deck with a lot of cracking and deterioration should be replaced for best results.

For the longest-lasting exterior paint, consider acrylic or enamel (oil-based) paints. Acrylic paints, including acrylic latex and acrylic enamel, are known for withstanding harsh weather and sun exposure. Enamel-based paints are also one of the most durable options available. While latex paint is common, it typically has a shorter lifespan than acrylic or oil-based options. The paint's finish also affects its durability; a higher gloss finish is generally more durable. For resistance to moisture and cracking, matte and satin finishes can be effective, while a high-gloss acrylic or oil-based paint offers a combination of maximum longevity and durability.

Pressure-treated wood lasts at least 10 years, but with the right care and treatment, it can last as long as 40 years. Painting the boards is one way to increase the lifespan of pressure-treated wood. The layer of paint provides extra protection for the wood against the exterior elements and insects.

Limewash and whitewash are two techniques used to give brick a light, matte finish, but they differ in composition, application, and permanence. The best choice depends on your aesthetic goals and the specific surface.

Composition

• Limewash: A natural and environmentally friendly option made from limestone, water, and sometimes pigments. It is breathable and soaks into porous surfaces like brick.

• Whitewash: Traditionally made from lime, water, chalk, and binders, but a similar look can be achieved with watered-down white paint. It is paint-based and sits on top of the surface.

Appearance and Finish

• Limewash: Provides a natural, textured appearance that allows the brick's character to show through. It offers a more traditional finish.

• Whitewash: Creates a softer, more opaque finish, often used for a rustic or shabby-chic style.

Application and Permanence

• Limewash: Is semi-permanent and can be removed, making it a good choice if you might want to change the look in the future. It requires more skill to apply and cannot be used on previously painted brick.

• Whitewash: Is a more permanent solution. It is more forgiving to apply and can be used on painted brick. However, because it sits on the surface, it can trap moisture.

Ultimately, if you want a breathable, natural, and reversible finish for unpainted brick, limewash is a great option. If you need a more permanent, opaque coating that can be applied over painted surfaces, whitewash is the better choice. Whitewashing may also be more economical, costing approximately $1.40 to $4.20 per square foot.
