Want the freedom to paint and weather your models safely and easily in your basement? MRVP’s David Popp shows how to make that possible by installing a fold-up spray booth from Micro-Mark.  Follow along as he talks you through the entire process — product assembly to venting exhaust to adding bright lights!

  1. Man, David can flat out build stuff. And one of the best teachers of anything, anywhere. Concise, comprehensive, and fun. Building my first layout, and anytime I run into a problem, I find a video of David solving it. Thank you!

  2. Thanks for the tip. That is a great addition to the spraybooth.

    Btw. interesting landscape on your model railroad in the background. I like the abstract concept with mountains of paper stacks and books. I have the same type of layout at home… 😉

  3. Hi, David, I missed this episode when it originally aired. Great suggestions from some of your viewers. Two things that I did, 1. I used plastic wrap to keep from getting a build-up of paint on the sides and bottom of the paint booth, and 2. I also used a piece of furnace filter in front of the filters in the spray booth to catch the overspread and such. My booth was purchased from eBay and it has the LA D lights that mount on the interior and that is a wonderful solution.

  4. PS.. Because my home made system employs a bathroom ceiling fan, and I wasn’t sure how much airflow or negative pressure inside the booth box it would generate, I did a little checking into the subject and came upon some industry installation data that says in essence, in order not to disrupt the flow inside the duct and thereby limit the amount of overspray the fan will remove, you should basically never have a 90 degree bend in the duct. The simple formula for optimizing the efficiency (OK HVAC engineers, don’t jump on this amateur if the terminology is a little off) the radius of the INSIDE curve of the duct bend needs to be 3X the diameter of the duct. So for a 5 inch hose like I believe David is using, the inside curve of the duct should be a 15 in radius — where’s my 15 in radius Atlas snap track measurement gauge 🙂 Ed

  5. Thanks David – Great how-to video. I created a home-made booth out of two, nested large plastic storage bins, metal vent ducting, and a bathroom vent fan (brushless motor!). Not as nice and portable as the Micro-Mark unit but it was really inexpensive and I can move it out to the garage when not in use. I intend to improve my setup based on the great tips in your video:Ed

  6. Thank You David, Calling Micro-Mark this afternoon for my booth. Really appreciate the info. Please stay safe.

  7. Nice project David. The turntable will also get grunged up with paint and dust. I cover it with disposable coffee filters.

  8. Parchment paper works well on the bottom to collect over spray. I hold it down will a couple of pieces of double-sided tape. Spray on!

  9. David, I am impressed at the amount of engineering that went into your project. Someone coming into your basement wood look at it and say, Cute. You have saved us all countless hours, money and missteps. One of your best videos. Thanks.

  10. David great video, i have a similar portable spray booth. Mine came with lights that fit right inside the booth. I love mine, the lights light up the whole inside of the booth. I got mine from TCP GLOBAL.

  11. Great video David, thank you. I have the same spray booth and had already built a window insert for my vent but didn’t know about that quick-connect adapter. I will have to look for it. One thing I found helpful was to put a handle on the MDF panel to make it easier to pull out of the window. As far as the cardboard in the spray booth, I keep a roll of butcher’s paper to cover the floor of the booth. Cheers!

  12. No bad experience with dryer vents, but have read warnings about possible fires simply from the lint accumulation; flexible dryer hoses are no longer recommend, I don’t think. May not be good to add even small amount of paint, or dull cote, etc. to the mix.

  13. Looks good! I’m very impressed with your portable light stand. You could also use that structure to attach an airbrush holder (it looks stable enough to handle that also). Another option to cardboard for the bottom liner might be wax paper or parchment paper. Both are available in grocery stores or big discount stores for a few dollars and a roll will last for years. Thanks for showing us this set up.

  14. David, you and the MRVP crew have done yeoman service producing numerous videos during the lockdown, thank you. Many don’t realize the amount of work that goes into making a video. It would be interesting to show the whole process from concept to posting. Might be a topic for a video

  15. David, I have a Micro-Mark portable spray booth. Thanks for showing me how I can set it up for basement use. Excellent tutorial!

  16. David, Thank you for the inspiration.I already have my Micro-Mark booth, just like yours. My advantage is that I intend to sit il on the clothes drier. Just have to work out how to connect the hose to the drier vent (already in place).

  17. Great video, David! It looks like a winner! It would also be great if you could do a video on your spray gun and compressor favorite set up. What kind of spray gun and compressor do you like best for infrequent and minimal spraying? All the best! Keep it up!

  18. Nice work. For a more permanent installation you could have used MDO ( sign board ) or plexi but for your application, MDF will work just fine for a long time. I was going to ask a few videos back, What your war game of choice was? This will also help you prime and basecoat those models but you all ready know that. Keep up the great work.

  19. I’ve been using one of these for a little over a year now, and I’m very happy with it. Even though I use mostly acrylic paint, I still vent through a window, and I found that some particulates must be making it through the filter, because the screen in my window gets lightly painted in a little strip the size of the exhaust vent.

  20. Neat. Especially if you have basement windows that open. Guess I’ll either drill a hole in the wall; or figure out some contraption to go in the outside door.All things considered (sounds like a name for a radio show), how do you like using your booth? Presuming, of course, that you have used it.

  21. David very well done. One suggestion would it be better to use a white cardboard/ paper base instead of the brown cardboard so as to reflect light back up on your project? As always enjoy your videos.
