Uggg. It never fails. I finally get my technique back and with the aid of a real nice gun you'd think I could spray like a machine. Not. I just cant seem to keep the dust out. Weve been cleaning the shop for a week. Using and air want, sweeping, blowing down trusses, walls, blowing out floor. Have a huge 36" fan to get the dust out. Each day cleaned and cleaned and cleaned some more. Still got lint in the paint. I shouldve rented a spray booth. :(

In the past I have built a booth in the shop out of painters drop clothes(Plastic ) build a frame of wood then just staple it to the frame
Are you wetting the floor?
I start by wetting it... then blow off the walls, lights and and ceiling... then wash the floor down again... then blow the car off... wet the floor.... tack off the car and paint.
I do sand and buff every job, so minimal dust isn't really a problem for me.
You beat me to it........Heck, sometimes I even wet the floor down in my booth depending on what I'm spraying........Quote:

The reason I mention, my first paint job was a Grand National. I was spraying PPG Base coat & Concept High Solids clear and the humidy was so high after wetting the floor the clear got milky. It was the middle of June so heat & cold wasnt a factor. I was told by my parts wholesaler that it was the humidity. After a couple of days in the sun it did clear up though. Now I'm spraying Concept 2020 single stage.
I sure was hoping to not have to ultra-fine and buff. Not for laziness but instead because I've been told that the single stage can chalk after time when its been sanded and buffed? Something to do with because the base and clear are together and the binding agent after buffing will have some base exposed. Whats your take?

your fan could be pullin to much sucking dirt .most all dirt comes off you and paint cup bottom sitting on bench . air hose in side and outside of the hose. car .you can blow shop out but this can add to more dirt up in the air so if you do this you have to let the shop sit over night . i allways wetted the floor . i painted cars for many years not very many in a real booth the cars i did shoot in them did not come out any cleaner then the many shops i shot paint in with out one
Pat,
After I cleaned the shop and used the air wand a couple of days, I did leave shop undisturbed over night. But I didnt wet the floor. I didnt use the fan while painting even though I sure was wishing I could. LOL's.
What you say makes sense. There is a fella around here that paints in a shop with a dirt floor. He does get a little dust but his paint jobs always turn out looking great.
I have the doors forward all painted. I'll try wetting the floor for the back half. Thanks.

wet the floor add a shot dish soap. then i used a push broom so the hose can not splash water up if you have low spots in the floors .you need to watch air movement that big fan you will need to have a window or door cracked to draw air from the out side some guy make up a insert with house filters the first 3feet of hose i wipe down with thinner . then a old tack rag . then tack rag the shop bench top the paper it off set gun on paper . tack off all your masking paper if you have any thing tape offQuote:

you can do slower reducer but it will take longer to tack off= dirt .start painting furthest from the fan helps with over spray as it pulls it over paint thats not wet small jobs a cheap house fan works very good .i used a house furnace squirrel cage fan that pulled low poor mans down draft and EX it out a window
dust is a killer. I just started a custom painting bussiness and don't have a good booth yet. Did you try spraying down the walls with water just before painting?
Me too but i also cut several holes in the side and ductape some cheap furnace filters in and then on one end cut a hole and seal in my giant shop fan so it sucks the fumes and overspay out, I also wet every thing down and leave the hose running on the floor.Quote:

So Built the booth,prepped,and left one bay door half way up and shot it,went back Monday and tore the booth down,no big deal. Tuesday we are working away on customers cars and I hear this chopper hovering real low,run outside and he's right over the power lines in front of the shop ????? Next thing I know I'm getting forms several different times from the County Air Quality folks with mandantory questions asking if we use spray equipment,grinding,sanding or sandblasting equipment etc. Nothing ever came of it but won't try it at the shop again. Only paint job I've got left on the agenda is the coupe might risk doing it @ the house,but the yuppies have me a little concerned so I'll probably find a shop to shoot it when the time comes.
You are kidding...arent you??:eek:Not allowed to paint in your own shop??That sux big time..I have heard that it is law in the nutty Ca..but I didnt know the rot had spread that far east..yeesh..Like to see that happen down here..There would be a lot of blood spilt..**)Quote:

I'm not sure what they would do to the guy spraying @ his home shop.
Thats scary..So you need a proper spray and bake type booth,a down draft,or similar,to do the job there?? And I suppose the fine would surely cover the expense of paying two guys to fire up the chopper to go have a look at whose painting illegally... Theres a lot to be said for living out in the sticks,and working from home then,isnt there??;)Quote:
