How NOT To Build A Deck - Ultimate Guide On Every Mistake You Can Make
What happens here
Observe any instances where multiple deck boards or flat surfaces are nailed or joined together without proper sealing. The video shows an example of six boards nailed together without any flashing tape. This creates crevices where water can sit and become trapped, leading to premature rot and structural degradation. Anytime two or more boards or any flat space where water can collect, proper flashing tape should be applied to prevent moisture ingress.
Goal: Prevent water trapping and rot by using flashing tape when multiple boards or flat surfaces are joined.
