Building a deck not only increases the value of your home but also offers a relaxing and entertaining space for guests. However, improper waterproofing can lead to serious issues. If you are in the process of building a new deck, you probably want to make sure it’s properly waterproofed to prevent damage from moisture. But waterproofing a deck can be a difficult and time-consuming task. Fortunately, there’s a foolproof method to waterproof your deck, protecting it from water damage and ensuring its long-lasting beauty. In this blog post, we’ll guide you on how to effectively waterproof your deck for a pristine look over the years.

How to Waterproof Your Deck Boards

When it comes to waterproofing your deck boards, the method depends on the material used. For composite boards, no additional sealing or waterproofing is necessary, as they are naturally resistant to moisture.

However, for wood boards, extra precautions are essential to safeguard them from water damage. Two effective options include using a sealer and applying a coating. Sealers, available in different finishes, can be applied every one to three years to repel water and enhance the wood’s natural beauty. On the other hand, coatings, made from materials like liquid rubber or polyurethane, create a thick protective barrier against water. Note that coatings may conceal cracks and splinters, making repairs challenging.

For a durable and long-lasting solution, consider using vinyl membranes. These waterproof decking materials can be installed on top of your deck boards, offering slip resistance and resistance to mould, mildew, and UV rays. Though they may have a higher upfront cost, they eliminate the need for frequent re-application like sealers or coatings.

Properly waterproofing your deck boards ensures an extended lifespan and a beautiful appearance.

Protecting Your Deck Substructure

Shielding the substructure of your deck from water damage is crucial. By applying deck flashing tape to the tops of joists, rim joists, beams, and the ledger board, you create a barrier that prevents water from seeping in and causing costly damage in the future.

Deck flashing tape is a simple and affordable solution that comes in different widths and lengths. Applying it is easy, and using a materials estimator helps determine the required amount for your project.

By taking the time to waterproof your deck properly, you ensure years of enjoyment, increase your home’s value, and provide a space for outdoor entertainment and relaxation.

How to Waterproof the Space Under Your Deck

Waterproofing the space beneath a second-story deck is essential to prevent water damage to the area below. To accomplish this, use sealants and flashing tape. Sealants applied to the joints of the deck boards prevent water penetration while flashing tape creates a barrier on the joists against water.

By using these solutions, you protect the space under your deck from water damage, ensuring it remains safe and dry.

Roof Deck Sleepers

Roof deck sleepers are a simple yet effective way to waterproof your deck. These pieces of wood elevate the decking boards off the ground or roof, allowing the wood to breathe and minimizing water damage. Avoid using chemically treated sleepers, as they are unsuitable for residential use. Regular maintenance is crucial for preventing wood rot over time.

Under Deck Ceilings

Installing an under-deck ceiling adds more living space to your home, but it requires an under-deck drainage system. Adding a vinyl membrane on top of plywood creates a watertight seal. While this approach keeps water out, it doesn’t redirect rainfall, so proper planning is essential.

Interlocking Decking Systems

Another option for waterproofing your deck is using decking systems with built-in water troughs. These interlocking systems direct water away from the deck and prevent it from seeping through the cracks. Ensure proper sealing around gaps between the system and the house to prevent water damage.

Under-Deck Drainage Systems

Under-deck drainage systems are waterproof gutter systems installed beneath the deck boards. They capture and redirect water away from the deck, providing optimal protection against moisture penetration. Using an above-the-joists drainage system ensures 100% protection for all joists and beams.
