booth curtain..

[Lizer]

So I'm in the process of building a new 30x48 shop with 14' ceiling. The paintbooth has its own 9x10 overhead door and the booth will be 13x23'. The back of the booth will be a permanent framed wall I'm thinking, which is where the intake will be, and a man door. The front of the booth with be an overhead door. The side of the booth will be the wall of the building...so the other side of the booth is going to be a curtain.

@OJ86 -- so you paint in that room with a tube heater in it and it doesn't mess the heater up with all the overspray or present an explosion hazard (if there's some kind of gas pilot light burning?) I thought an infrared tube heater would be great but didn't think it could go in a spray booth. My shop is heated by radiant floor heat so the car will be sitting on a warm floor too. Maybe the IR tube heater wouldn't be necessary. My builder is installing the overhead door on a high rise track which I see one of your doors has, but your door with the heater is on a low rise track, I'm assuming so the door can slide up below the heater.

@Dean Jenkins With the 3" unfiltered gap at the top of your curtain, how is the cleanliness in the booth? I'd be worried about pulling in dust floating in the air from the rest of the shop.

There is only a flame when its running, but its all pretty sealed up, and when the fans are on there is a ton of air flow and the concentration doesn't get to the point where it could explode(I hope....fingers crossed)

The door is way lower than the heaters and it doesn't even go back that far when its opened.

one thing I don't like about the placement of my heaters is that depending on how the parts are sitting in the booth area it can get the parts pretty hot. So I have to sometimes be careful how I position things.

It hasn't been an issue for me. But my exhaust vents are in the ceiling so air coming in through the top gap of the curtain doesn't get pulled down towards the vehicle. This works pretty well to evacuate paint most overspray as it seems to mostly rise up.
If I need more air movement to get overspray out (usually clear needs this) I open the roll up door a few feet and put a 24-inch fan in the opening and pull air out from the bottom in addition to the ceiling exhaust.

Like you, I do a shop blow down the day before and let it settle really well before painting.
