Why is Choosing the Right Deck Finish for Pressure Treated Wood Crucial?
Choosing the right deck finish for pressure-treated wood is crucial for preserving the wood’s integrity and extending its lifespan. The appropriate finish protects against moisture, UV rays, and environmental damage.
The United States Department of Agriculture (USDA) defines pressure-treated wood as lumber that has been treated with a chemical solution to resist rot, insects, and decay. Proper finishing adds an additional layer of protection.
The importance of selecting the right finish stems from several factors. First, pressure-treated wood is often high in moisture content right after treatment, which can lead to issues like warping or cracking if not properly sealed. Second, finishes help prevent the wood from absorbing water, which can promote mold growth and further deterioration. Lastly, finishes that include UV filters will protect the wood from sun damage that can cause fading or splitting.
Technical terms involved include “penetrating finishes” and “film-forming finishes.” Penetrating finishes soak into the wood to provide protection from within, while film-forming finishes create a surface barrier. Each type of finish has distinct properties and applications.
Understanding the mechanisms is vital; for example, when water penetrates unprotected wood, it can lead to swelling that alters the shape of the boards. In contrast, a good finish repels water and prevents these changes. Similarly, UV rays degrade lignin, a component that helps maintain the wood’s structure. A finish that blocks UV rays will help preserve the wood’s strength and appearance over time.
Specific actions that contribute to degradation include neglecting to apply a finish after installation or using the wrong type of finish. For instance, using a film-forming finish on newly treated wood that still has high moisture content can trap moisture inside. This can lead to peeling and other failures. Conversely, regular maintenance, such as reapplying the finish as recommended, can significantly extend the life of the deck.
