PB is finally ready to try to find a fix for the red streaks. When, I did not give him his last draw, he suddenly came up with a suggestion. He wants to spray a thin coat of light gray colored epoxy on the deck. We asked for pictures or samples of what the deck would look like. He said he could not provide any, because it had never been done before. ??? I said make me a sample on a piece of plywood. He said he could do that. Does anyone know what he's talking about? BTW, he does decorative concrete work too, but he said this would not look like that. He claims, my finished deck would look like even colored gray concrete upon completion. We made it clear we did not want the deck painted. Any input out there? Thanks, again
