Its self-adhesive design seals tightly around screws and nails, preventing water infiltration. When installed between treated lumber and metal, it also prevents metal corrosion, extending the lifespan of your deck. Engineered for reliable protection, this tape is an essential solution for maintaining deck integrity and durability.
