I put two 4'x8'x1/2" sheets of laminated fiberboard that I purchased at Menards on top of our no longer used ping pong table in the basement to use for spray basting. Cleans up with soap & water easily, although pointing the spray toward the center prevents a lot of overspray. Tape the backing to the laminate with blue painters tape, then spread out the batting and fabric from the center. Right after I spray I leave the basement, and it doesn't circulate to upstairs.
