Hi folks and like others, I thank you for the great info you provide on this site. My issue revolves around finishing my IPE deck. I built the deck last year after getting great info off of this site. The deck looked fabulous, and I finished it with TWP 116 just using a paint pad. The winter ice seemed to do a number on the finish though (or I did something wrong in applying it, as try as I might I definitely ended up wiht a slightly uneven looking application) and it has faded, with a bunch of grey patches showing through.

I bought some standard Olympic deck cleaner and washed it this weekend, noticing that wherever I really scrubbed the spot went completely grey, removing all the finish. I am planning on doing another coat of TWP 116 next week (still pretty warm here in VA), so here's the question: Do I need to completely remove the old finish? If so how? Is it best to use a pressure washer or a stripper (the deck is a bit to big to hand scrub the whole thing)? What other prep should be done after washing or stripping? Many thanks in advance for any help here!
