How to Waterproof a Deck Over Living Space

Are you planning to create an outdoor living space and want to waterproof your deck over living space? Waterproofing your deck over living space is an important step to prevent water damage and leakage. In this article, we will guide you on how to waterproof your deck over living space in a few simple steps.

Step 1: Prepare the Area

The first step to waterproofing your deck over living space is to prepare the area. Remove any debris, nails or screws, and clean the surface with a deck cleaner. Check for any damage or cracks and repair them before proceeding to the next step.

Step 2: Install the Underlayment

The second step is to install the underlayment. Apply a layer of underlayment on the deck surface, extending up the walls by at least 10 inches. Use a waterproof membrane that will protect the deck from moisture and water damage. Ensure that the underlayment is properly sealed around the edges and seams.

Step 3: Install the Flashing

The third step is to install the flashing. Flashing is a metal or vinyl material that is used to prevent water from penetrating the underlayment. Install the flashing around the perimeter of the deck and on any vertical surfaces, such as walls or posts, using roofing nails or screws.

Step 4: Apply the Coating

The fourth step is to apply the coating. There are different types of coatings available, such as liquid coatings, sheet membranes, or rubberized coatings. Follow the manufacturer’s instructions for applying the coating, and ensure that it is evenly distributed and covers the entire deck surface.

Step 5: Allow to Dry

After applying the coating, allow it to dry completely. The drying time may vary depending on the type of coating used, the temperature, and humidity. Ensure that the area is completely dry before using the deck.

Step 6: Inspect and Maintain

Regularly inspect your deck for any signs of damage or wear and tear. Keep the deck clean and free from debris, and avoid placing heavy objects or furniture on the deck. If you notice any damage, repair it immediately to prevent further damage to the deck.
