I was excited to see this thread but unfortunately there's no input.

Dang.

I have the same issue. Ugly and faded 30 year-old Kool Deck which I applied a layer of Supercrete (some kind of concrete recommended at the time) over the deck which actually lasted about 8 years before it began to fade off. Now 12 years later I'm back to square one and thinking about having the deck stained,

A contractor in the Boston area with a good reputation is recommending I go this route as a cheaper alternative to rebuilding the old deck. He wants to power spray the deck to remove the loose Supercrete and Kool Deck and stain over that. I'm concerned about the deck becoming slippery and general appearance.

Any level of comments or insight about this situation would be greatly appreciated,

Thank you!
