I have tried what I feel is just about everything to help control dust or rather the particles from getting in my finish.

I’m working on a blue painted, pre-catalyzed lacquer job right now and it seems no matter what I do, I cannot stop a speckle here and there. (I even sent my gun out to my supplier A Kremlin airless air assist pump to be cleaned thoroughly)

I also find possibly a fiber from my clothing getting into the finish as well.

Are you guys wearing suits when you do this? If so, where did you buy it and did you find it helpful?

What else are you guys doing to help control the dust or particles from getting into the finish?

I have even tried blowing it off with one hand and the gun in the other as soon as I am done completely blowing off, I shoot the finish immediately but for some reason it’s still will not control the dust or whatever is getting into the finish. I don’t always notice it right away, but it becomes more noticeable when it starts to dry. I don’t turn on my booth while I am spraying, because I’m concerned the booth is sucking dust from throughout the shop into the booth and onto my finish. I even wet down my floor and sprayed liquid fabric softener out of a pump sprayer to help attract the dust I have also reached out to a company that sells a product that you spray on the walls, the floors, etc. and is a sticky product that is supposed to attract airborne dust to the floor and wherever you spray it. They’re going to come by and show me a demo of it to see if it helps. Do any of you have any experience with this? has it helped?

What suggestions and recommendations do you guys have for the best dust to control when using an open booth? Thanks

a shoot suit is a good option for u vs a tyvek suit

an open front spray booth is a vacuum cleaner so to speak. it sucks in height x width x approx 100fpm. it is sucking the shop air , dust etc.

a possible option is front filter doors. take the number of exhaust filttele itr you have, double and use apporx 20-=20 intake filters, the tackified side faces the insisde of the spray booth.

do you have a variable speed drive on ur fan. if not get one...do single phase power, take the hp x 2 and that will be t
he size you need hp wise.
those are about the best options outside of an air make unit

If the fan is variable, I have no idea how to adjust it. I do have a make up air system. I don’t turn on either one of them when I am spraying

Where did you get the suit you wear? Any idea of where this particulate is coming from? I guess I would’ve thought my wedding down the floor, the walls and also using fabric softener, then it would help greatly. Because of static electricity, I’m assuming, as soon as I pull the trigger of the gun, the crap is being attracted to the finish.

I have the cleaning needles that I used to pick out things here and there, but on paint jobs it’s very difficult because you will see everything.

Where do you get this shoot suit from? Is there a particular style that you use? Approximately how much is it? Why do you like that more than the Tyvek?

Herb,

The other challenge is, I’m a cabinet maker plus do refinishing, so the dust is unavoidable completely. I don’t know if I will be wasting my time by taking a leaf blower and going up on the ladder to blow off all the rafters, etc. and then to use that sticky chemical to spray around my shop. I don’t want to sound OCD, but it irritates the hell out of me that I have to end up with a particular here and there.

For instance, today when I was spraying, I did not create any dust today, so I let the dust settle overnight and then came to spray and it’s still the same crap.

We used to spray with parts laying flat which I assume you are also doing. When we started hanging and spraying parts vertically we noticed way less dust in the finish. It took some getting used to but made a huge difference. It's also much faster because you can usually finish all sides of all parts at the same time.

This may be common sense but it's worth noting, be sure you tack
the item off real good before even starting spraying.
A lot of times dust is still on there even when you think it's not.
Static can also be a big problem. Static will suck the dust to it.

If you are not replacing the air you exhaust in the booth with clean air from a makeup fast enough, your booth fan will be starved for air and start pulling dust from every corner of your shop. Your pieces may also get a slight static charge (especially when it gets colder I've noticed) and attract fibers from the air. You can use an anti static air gun to neutralize the static charge.

Craig,

I was introduced to a chemical that you mist on your floors, walls and fixtures, using a bug pump sprayer, to attract airborne dust. I am under the understanding the more applications you do of this, the better the results. I have a guy coming by my shop from the manufacturer of this on Tuesday to demo the product. It’s like $50.00 a gallon and is supposed to do 14,000 sq ft.

It will be really interesting to see if it works

Regarding my make up air system, I’m already concerned that is blowing dust from the rafters, etc. toward the booth and into my finish, which is why I don’t have it or my booth turned on when I spray.

These little particles are driving me bat shit crazy

I wear a nylon coverall with carbon threads woven in. It dissipates static charge. It has made a huge difference in the amount of dust in my finish. Winter particularly when the air is so dry. The CV I spray is highly charged when scuffed and blown off. I do an initial blow off well before spraying and limit the amount I do in the booth.

Tom, I have sprayed inside and outside the booth, along with going to the extent of building a enclosure around the front of my booth in the main area made out of2x4’s, 4 mil plastic and adding furnace filters here and there to allow airflow to come in and even using a Fastcap dust door so I can get in and out…… And there really was no difference between the two. I have a booth coating I spray on the galvanized metal. I know that collects overspray and I thought blowing that off and even wetting it down with water would do the trick, along with fabric softener in a pump sprayer, but I’m still getting crap in the finish. I’ve even waited all night, come back the next day without kicking up any dust… That I know of and then spraying and it doesn’t do much of a difference.

Myself being a custom cabinet maker doesn’t allow for me to have much of a “dust free” shop. I’m a one person company and I cannot go around and continually blow out the entire shop, as I can spend days doing that.

I got on a ladder yesterday to go up to the ceiling 17 feet in the air and blew off the top of the rafters, fixtures, etc. so now my last course of action is this chemical I will be trying out on Tuesday which has I believe an electric charge to it that attracts dust and hopefully the dust will be attracted to that versus my finish or will at least limit it. I also bought a Tyvek suit from Sherwin-Williams and we shall see how well that works

how do you adjust the vfd. how many cfm is ur air makeup unit and how many hp is ur fan and size.

is your booth enclosed

i wear the shoot suit because it breathes, just look up a supplier on the internet.

have u sprayed ur coating on a piece of glass and had ur supplier or mfg of the coating try to identify the particulate

one other suggestion, take one of ur siphon guns or a gravity feed gun and see if you have the same issues.

one with the airmake and fan off, the other running.

is ur air make up directlyconnected to the booth

do you have a diffuser on the outbound side of the air make, remember if you don't have a large diffuser, the air coming out ofo the a/r is really screaming and that might be disturbing the particule in your shop

i really doubt ur kremlin is the source of the particles that go on ur finish but one way to tell is you get the same issue with a gravity or siphon gun.

i know it is a lot of work but some of the questions might help you narrow down ur issue

good luck herb j

The quality of my finished product took a big leap forward when I bought an anti-static coverall.
