Mastering Deck Finishing: Sealing the Bottom for Longevity

Finishing off the bottom of a deck is a crucial step in completing your outdoor living space. Not only does it enhance the aesthetics of your deck, but it also provides safety and protection from elements. Let’s dive into the process of finishing the bottom of your deck, ensuring it’s both functional and visually appealing.

Before we start, it’s essential to understand that finishing the bottom of your deck involves more than just adding a skirt or lattice. It’s about creating a cohesive look, improving safety, and preventing debris and pests from accumulating underneath.

Choosing the Right Finish

Selecting the right finish is the first step in completing the bottom of your deck. The finish you choose should complement your deck’s design, material, and your home’s exterior.

1. **Deck Skirting**: Deck skirting is a popular choice for finishing the bottom of a deck. It’s a decorative panel that hides the underneath area, creating a clean, finished look. Skirting can be made from various materials like vinyl, composite, or wood, and it comes in different styles to match your deck’s design.

Vinyl Deck Skirting

Vinyl deck skirting is a low-maintenance option that’s durable and resistant to rot, insect damage, and fading. It’s available in a variety of colors and styles, making it a versatile choice for many decks.

Pro tip: Choose vinyl skirting with a textured surface to mimic the look of wood grain, adding a touch of elegance to your deck.

Pro tip: Opt for composite skirting with a grain texture to create a natural, wood-like appearance.

Installing Lattice for Ventilation

Installing lattice is another effective way to finish the bottom of your deck. Lattice provides ventilation, preventing moisture buildup and reducing the risk of mold and mildew growth. It also adds a decorative touch to your deck.

1. **Picking the Right Lattice**: Choose lattice with a design that complements your deck and home’s exterior. Common lattice patterns include square, diamond, and scalloped.

Installing Lattice on Concrete Slab

If your deck is built on a concrete slab, you’ll need to secure the lattice to the slab. Use concrete screws or anchors to attach the lattice to the slab, ensuring it’s level and secure.

Pro tip: Apply a bead of caulk along the seam between the lattice and the concrete slab to prevent water from seeping through.

Installing Lattice on Posts

For decks with open space underneath, lattice can be installed directly onto the deck posts. Measure and cut the lattice to fit between the posts, then secure it using screws or nails.

Pro tip: Ensure the lattice is level and the spacing between the lattice and the ground is consistent for a polished look.

Adding a Barrier for Safety and Pest Control

Installing a barrier around the bottom of your deck provides an extra layer of safety, preventing small children or pets from crawling underneath. It also helps keep pests like rodents and snakes out.

1. **Using Hardware Cloth**: Hardware cloth is a durable, galvanized steel mesh that’s perfect for creating a barrier around the bottom of your deck. It’s available in various sizes, so choose one that’s small enough to keep out pests but large enough to allow for ventilation.

Measure and cut the hardware cloth to fit around the bottom of your deck posts. Secure it to the posts using staples or screws, ensuring it’s taut and secure.

Installing Hardware Cloth on Concrete Slab

If your deck is on a concrete slab, you can install hardware cloth around the perimeter. Use concrete screws or anchors to secure the hardware cloth to the slab, ensuring it’s level and taut.

Pro tip: Apply a bead of caulk along the seam between the hardware cloth and the concrete slab to prevent water from seeping through.

Finishing the bottom of your deck not only enhances its appearance but also adds value to your home. Whether you choose to install skirting, lattice, or a barrier, take your time to select the right finish and ensure it’s installed correctly. Your completed deck will be a welcoming space for you and your family to enjoy for years to come.
