21POLYPLUS is a water-based, environmentally-friendly, coating that offers two-fold protection for marine pilings and the environment.
21POLYPLUS has been proven to encapsulate the preservatives (CCA) used to treat marine pilings, preventing them from leaching into the ecosystem. In many states, the use of marine-treated lumber is now being regulated and in many cases, pilings must be coated with a product like 21POLYPLUS. Our coatings have been used to protect the pier at the Statue of Liberty, the Port of Los Angeles, and many more notable structures.
Secondly, 21POLYPLUS prevents harmful marine organisms, called marine borers, from attacking marine pilings, extending the life of marine pilings indefinitely.
One kit (5 gallon pail) of 21POLYPLUS will complete (2 coats) approximately 140 square feet of surface area.
Tintable to any color – add 1 gallon of exterior latex paint to the kit for color.

I haven’t used this product yet but can I use this on concrete walls of a pool to keep the walls watertight?

We recommend PoolPoxi, Encore’s durable epoxy pool finish for the purpose you’re describing. Thanks for the question!

Applied this to CCA piles very easily. The material is very durable. It was hard for our chainsaws to cut through and the blades dulled pretty quick. That said, the product held up througout the construction of the pier and it has worked out really well. Much more affordable than the “pre-wrapped” options that are out there. I also liked the fact that cuts that we made to stringers could be patched on the site with the same material. Overall, it was easy to use, it was affordable, and it’s working great.
