What kind of paint did you use on the floor? 60 days huh? I am waiting till no fear of another freeze . . . probably right after first week of April, can't imagine waiting 60 days after that! 2 inches of sand, layer of poly, 2 inches of styrofoam with grooves for wirsbo tubing, topped with 6 inch wire mesh. Can't wait to see that gray concrete finish! I shoulda busted my butt and did this last fall . . . always something else taking priority. My wife is having kittens now over the fact that her parking spot is still full of truck parts, tools, and all manner of "junk" (her word, certainly not mine) grin
