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.

Satin paint is generally considered a better choice for woodwork—including trim, baseboards, cabinets, and doors—than flatter finishes like eggshell or matte. Its soft sheen enhances architectural details and stands up well to frequent cleaning and daily wear. Compared to eggshell and matte finishes, satin is more durable for high-touch areas because it is less porous and doesn't absorb dirt as easily. Matte finishes, in particular, are prone to scuffs and are harder to clean, making them less practical for surfaces like doors and cabinets.

It’s often best to spray on deck sealer. Sprayers can apply sealant more quickly and evenly than rolling while still enabling you to reach tight spaces. When using a sprayer, always use a low-pressure setting at a close distance to ensure an even application. Avoid using sprayers on windy days.

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.
