I am building a spray booth using wood. I want to use half inch white mdf melamine but I can't find any locally even though I am in a major metro area (WDC). Are there any coatings that would work on plywood as a substitute? Would white shellac on MDO be a suitable alternative? Or would it be better to put white laminate over a substrate?
I type on a tablet. Please excuse the terseness and the autocorrect. Not to mention the erors.
Unless it has to look like it's some part of decor, I would just do plain old plywood. It will soon be multicolored on the inside anyway.
Have you looked at shops that sell cabinetmaking materials? They're the best source for melamine, baltic birch and veneer plywoods.
You can get white smooth bath panels from any of the big box home inprovement stores. Can also get white laminate from most any floor covering/cabinet shop. You can use contact cementand put laminate direct to MDF particle board.
I'd kind of be concerned about weight, if it ever needs to move. A half sheet of the above will be 30 pounds or so.
Maybe 1/4" would be better. In which case pre-finished sheets should be easy to find.
The interior of my booth is a mix of Navy Blue, Haze Gray, Hull Red. Occasionally I hit it with a blast of cheap white Krylon rattle can stuff.
Modeling is an excuse to buy books.
I built my latest one from 1 x 2 frame and quarter inch plywood. I used a couple coats of prime then spray can enamel. The inside sheeting is quarter inch foamcore, easily replaceable so I have no need to repaint anything. Just cut new foamcore panels and insert.

I built mine out of foam core. Glued it together with Shoe Goo held in place with Duck Tape ( SG is kind of slow drying but holds well once dry). You could get fancy and cut in lock tabs I suppose but I didn't do that. The bottom/floor is regular hard masonite.
I built mine with regular mdf and undercoated then painted the inside, works fine.
Unless you need to match existing decor, you could try clear lexan or clear 10mm Twinwall Polycarbonate, lifgtweight, & on mine I put al LED light strip outside the box to light up the spray cab.Here is mine, self-built:

I like that idea, gonna be moving all my gear into one room soon and I may just go with this idea instead of moving my current spray booth which is a bit fragile anyway.
Sheets at the big box stores around here are particle board, not mdf. And they don't list having half inch boards.
I was doing white just to have a brighter interior. I just had an emergency vitrectomy - I need all the help I can get!

Particle board will be fine, i used a regular high volume brushless extraction fan. Works a treat.

I have a couple of empty plastic storage tubs down in my basement waiting for one to be butchered, I mean reconfigured, into my second spray booth. I'm thinking of going back to shooting solvent based paints down there and keep my upstairs booth just for acrylics. I have a window down there that needs reframing anyway and I can add a fan there.. I used to spray Floquil down there years ago. Anyway, I've seen a couple of videos where guys have used storage bins or tubs to build their booths from and it looks like a decent idea and easy conversion.
