## Customer Reviews

### ⭐⭐⭐⭐⭐ Work great on the deck
*by R***F on August 12, 2024*

I purchased six of these rolls for a 16x16 deck and had one left. This is an awesome product to prevent water from getting on the framing boards.

### ⭐⭐⭐⭐ Does it's job
*by R***L on May 20, 2023*

It'll get the job done. It's a little difficult to layout because it sticks to itself and the glue leaks out the side of the role.

### ⭐⭐⭐⭐⭐ Works just like it should
*by R***T on September 26, 2022*

Super sticky and worked as it should. Found it easy to roll out and cut. Did have a couple times where the paper was tough to get off when it did a partial strip. Overall very satisfied
