Re: wash bay in shop??
I have a 32 x 60 wash bay lined with steel, steel lined ceiling, with 2 rows of 110 watt HO flourecent lights on the ceiling, then a string on the walls about 4 ft off the floor, the side lights plug into regular wall plugs, I used pvc electrical conduit to seal as much as possible. I have a 24 x 16 overhead door. I made my trough drain 15 in wide and 14 in deep and about 30ft long , with the top drain covers 17" x 1.5" deep. I made the drain covers 3/4" less than the recess of cement on the sides ( height is same as floor so creeper rolls over ) , so smaller dirt and water will drain easily. I can also use my drain to pull air down and make it a downdraft paint booth. I have one 36" std walkdoor, and one double 36" doors, so that I can move items on pallets back and forth from my washbay and main workshop. I have a 36" livestock fan located between both shops to ventilate either side. I love my wash and paint bay, and I am glad I made it a permanent wall instead of a tarp. I have floor heat and just love it as well. I farm and am an independant mechanic and fabricator, so I use my shop hard everyday ! I also built my "stick" building on a 12" concrete wall so the water puddling is not a problem around the posts, but with the floor heat, it dries p very quickly any way, plus I have my grade at 1" per 10 ft from the drain, it pracically drains itself without squeegee. The only thing I would possibly change would be making the double doors higher, do I could run my forklift through. I have a hot water steam cleaner and use it everyday, sometimes all day when washing combines, it can get a little foggy sometimes if I do not run the fan. When I paint I open the far single walkdoor, and pull warm clean air from the main shop, and then use the exhaust fan to rid the fumes and mist, then they pass thru a water spray over a furnace filter to eliminate chance of paint mist on the outside of my building. I also use a air recirculator ( homemade ) when paintiing in severe cold, to keep heat in.
