Unless you’re using a 2-in-1 formula or painting over an existing coat of paint, it pays to apply a coat of primer ahead of your new paint. Decks see a lot of footfall and exposure to extreme and sudden temperature changes and moisture levels. The primer promotes better paint adhesion, moisture repellency, and a smoother finish, which means you’ll often need fewer coats of paint. 

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.

You’ll need to restrain your deck when you notice fading, cracking, peeling, or mold and mildew over a moderate to large area, or when it’s become especially difficult to clean. As for how often to stain a deck, plan to do it every two to three years or whenever you start to notice extended damage.

It’s best to use an exterior latex acrylic paint to promote maximum adhesion to composite decking. This flexible paint type can better cope with the natural expansion and contraction that can occur with composite deck boards. Oil-based paints won’t adhere as effectively and are more likely to crack and peel as the boards flex. Testing whether your chosen paint will stick on an inconspicuous section or a spare board is a good idea.
