Hi: I am a great fan of your products. I have used all of your epoxies to repair our rotted windows 2 yrs. ago and they look great, I estimate you save me around $70,000 (if I had replaced the windows).

I have a new project, preserving the wood planking of our dock at a fresh water lake. The wood is 18 yrs. old and has a lot of surface cracking and checking. It is structurally sound. I am coating the boards after thorough power cleaning with CPES. Do I need to apply a topcoat? Appearance is not an issue. I like the rough rustic look. I assume CPES alone will withstand the weather in our northern climate. Am I right?

Well, thanks for the kind words!

The CPES will help preserve the planking. However, like all epoxies the surface molecules will gradually deteriorate with UV light exposure. The epoxy that is in the wood is not affected. The surface will take on a light grey tone, which serves as a kind of UV blocker for the epoxy underneath.

And, as always, feel free to come back if you have additional questions.
