Hello LumberJocks,
I have been asking a lot from you guys lately but I have been getting such great information I can’t help but to keep reaching out to you guys. So my most recent dilemma is that I have purchased a Fuji Minimite 4 HVLP with a G-XPC gravity fed spray gun. I could not be happier with it. It has taken my finishing abilities to places I never thought they would be. But the problem is although over spray is somewhat controlled there is still over spray. As of right now I cover all my major tools with blankets sweep everything up and spray. My complaints are
1. It is quite a process to cover everything and clean everything before I have to spray. Then I have to do the exact opposite when I am finished.
2. While things are drying I can’t do anything. I don’t want to uncover anything fearing I will create dust. So all my Woodworking comes to a complete standstill.

So I guess I am reaching out to see what some of you guys do. I know I can’t be the only one that has this problem. Spring is right around the corner so soon I will just be spraying outside but until then and in future cold months what do I do. I am open to any and all suggestions from simple to complex. From cheap to expensive. Just want to get some ideas and see if I can make something work for me.

As always Thank you very much.

1) Really cheap 6×9’ tarps are often free at Harbor Freight. If you were forced to pay for them, they are pretty cheap. Depending on the size of project you will need to prop up a big enough frame to allow the piece to be totally inside the enclosure.

2) The absolute best is if you have ample room, and can wall off a place just for finishing, with something like that you can make a booth that you can close pretty well, or set up a finish room not in your shop. I do mine downstairs (basement) which is climate controlled, so I can finish year round. I have made up a knock down room and use a few of the Zip Wall Zippers so you can essentially put a door into your finish room. I have not tried one in the shop, so I cannot guarantee if it would keep dust out. Mine keeps any overspray down, and I vent mine out through a vent in the window block, so fumes are not a problem. It’s possible if there were a bit of distance you wouldn’t have a problem with dust getting in, if you taped the seams real well. It would be easy to test on some scrap, if you were practicing a finish.

My inside booth uses the garage door rails as 2 sides of paint booth. Unplug opener to avoid surprises, tape plastic to inside of door, hang tarps/plastic over rails instant 3 sided booth. If I need a 4th side, place a 2×4 over the back of rails and hang plastic on it. With 4th side added, I can work in garage on small things outside the booth. Nice thing about this, do not need to clean or move any thing sitting near walls outside the booth. Just push the tools out of the area, set up booth, move project parts into it and spray away.
This is not my idea, I saw here it on LJ somewhere. :)

My outside spray booth is a dozen 2×4 screwed together to make a box that sits in side yard. Have a couple of plywood triangles on both sides of 2 corners adjacent to each other, and opposite the opening. Use those freebie HF tarps and typically make a 3 sided spray chamber. Occasionally use some plastic film or tarp on 4th side when it gets windy in afternoon to stop dust migration. HOA doesn’t like my blue monster left up permanently, so I assemble/disassemble as needed in about an hour. During repeated use, leave top assembled leaning up against fence, and add legs/tarps when needed.
I have used this same type of 2×4 booth indoors when I had single wide door on a 2 car garage and didn’t want to commit 3/4 of garage as spray booth?

Only problem with 4 sided booth is over-spray control? At old residence I added a box fan with a furnace filter taped on it, located in middle of back wall of booth. A bit redneck, and not meeting code for solvent spraying; but it worked well to pull over-spray away from the project and filter keep over-spray from getting all over the rest of garage on big projects.

Best Luck.

I built panels from 2×2 and plastic sheeting. They bolt together using T-nuts to create a room. I keep positive pressure in the room by blowing filtered air in and exhausting outside through another furnace filter. I’m fortunate to have a separate one car garage I dedicate to spraying. It takes 45 minutes to install. My original intent was to erect and when needed take down so the wife could park inside. The turbine sits outside the room and I wrapped LED lights in plastic wrap.
I researched pretty hard on the internet and cobbled this together to fit my needs. No regrets but it could be better with more light and a door on the exhaust side of the booth.
FWIW, I also have the Q4 Gold gravity and love it.
Good luck.

or it’s little brother:
I have both. Still need to ventilate if inside but both of these shelters easily takes care of overspray.

I have been really looking at those. How quickly can you put up the big one? How durable is it. Does it take up much room broken down? And does it really contain most of the over spray. Will the shop still fill up with a cloud? I’m guessing with no ventilation that would be the case.

something that I don’t see discussed here is the floor of peoples shops.
when I had my sign shop, it was imperative to have a dust free environment.
I bought the sawdust floor sweeping compound and used it religiously.

it is basically sawdust, sand and some kind of mineral oil and liquid furniture wax.
you could make it yourself by saving your sawdust and buy a bag of sand and the
appropriate oil at BORG. avoid any kind product that contains silicone on your floor.
also important is the broom – a 24 – 30” wide push broom with soft nylon bristles
to push the sweeping compound around will do wonders for a clean floor.
avoid the stiff bristle brooms as all they do is kick dust back up into the air.
no matter how good your vacuum system is, you still get airborne dust that settles on the floor.
shop cleanliness is one more step to professionalism.

Mr. Smith,
I couldn’t agree more. And I do not only take pride in my work I take pride in my shop too. And I do try to keep my shop organized and clean. But as I am sure must of us know one thing leads to another and the next thing I know my shop is a mess. I always tell myself I am going to just clean up every night but something always comes up. Work wife kids dogs the house. It never fails. Plus my shop is a work in progress. My Most recent project was sheetrocking and painting the ceiling. Well in the process of doing that things get moved around and unhooked and just chaotic.

But my point of this rant is that I want to thank you John for pointing out how important shop cleanliness and organization is. Because of your reminder I am putting everything on hold and spending some shiop timejust cleaning and organizing. I have been having a hard time figuring out exactly how I want my shop. One of my short comings is figuring out where everything works best and committing to it. And I think if I put more time and effort in to that maybe getting things clean and ready for spraying won’t be something I dread so much.

I have both but have only used the small one so far. I liked the small one enough to purchase the big one to be used when the weather allows it outside because no room in my workshop for something that big.
The small one is a pop up and contains overspray, yet does nothing for the cloud that comes with spraying. I have a $5 1HP delta DC I snagged at an auction, and thinking of doing some outside ventilation with that.
Durability? Hmm.. it’s basically a pop up tent with the same material.
