Replace floor with??

[Huron Blue]

Just about done now I think one of the reasons it's best to do pieces is a sheet of plywood is naturally not perfectly flat. Doing it in pieces helps straighten that out and easier to judge and deal with the resin mixing when your not doing a lot at once. I had an issue once after only a few minutes my resin bucket got too hot to touch and it wasted about 1/2 a gallon! Guess I should have kept it on ice or something? But ever since then I've been a little gun shy of mixing a lot at once.
