Re: Rat repair.
 

Ok so as i posted the rust repair on the driver side is done but i had some surface rust on my front fender, i did some sanding on it and brushed the inside with rust treatment, however it was just too cold to sand and cover the fender with 2K primer.

Working under the car cover i have limited space to work, i will need to pull the truck out and turn it around to start the other side, i didn't want to do that with the fender off so i kinda fell into hold mode and started researching a bit on paint booths.

So the past week has been really nice outside, so nice that i got sprig fever and didn't touch the truck, what can i say.. This weekend i finally started building my small paint booth, i'm at the point i need to start covering it in plastic.

Which brings me to the question, do i plastic the inside or outside?? This will be a positive pressure, fan pushing air in, 20"X20" fan will have a filter plus 2 20"X20" filters for the exit, the far wall will be hinged and latchedand have foam weather stripping to make it air tight..

Re: Rat repair.
 

The fan should be at the bottom and pull air out install filter at the top to filter the air coming in. blowing air in will blow in dust bugs and small debris. Rap the visqueen around the out side.

Re: Rat repair.
 

I agree with Dwilbur, that's how I did mine. I also placed a couple of small electric heaters just outside the air inlet filter and it helped keep it toasty warm inside.

Also place put a filter before the fan if you don't want it painted.

Re: Rat repair.
 

So i was going to tape the filter to the outside of the fan so the air coming in is filtered, reason was i thought i read somewhere about having a positive pressure in the booth, so i guess that is wrong and i need to pull the air thru.....

I posted the same question on the paint forum a while ago too, no time to do any more today anyway so i'll see what they say as well.

The good news is i use the same size opening on both sides for filter and fan so its an easy fix, just a little more time involved..

Re: Rat repair.
 

Being in a negative helps remove the fumes, doesn't blow your paint around as much and having some sort of a door that's overlaps on the outside will be kept closed by the suction. At least this worked well for me, I painted a couple trucks this way. You still should have at least an organic filtered mask or an air supplied respirator !!!

Re: Rat repair.
 

Got the respirator covered. Do you think i will need 2 fans or just the one?

Re: Rat repair.
 

That's a fairly small enclosure, you should be fine with one fan. Your biggest place of air flow restriction would be your inlet filter, maybe put in a second filter. I imagine your fan is a 3 speed, so you can choose what speed works good for you.

Re: Rat repair.
 

Yes the two squares in the frame on the other side are for 2 filters, 20"X20", plus 1 20" x20" to cover the fan.

No pictures today but i moved the filter frame to the top of the wall where the fan was, then moved the fan where the filters were originally going to go, also added a second fan frame for an additional fan if needed.

Re: Rat repair.
 

So fighting some back strain today and my chiro is out today.... so won't get the booth finished.

But i have the framing all done less plastic and putting the hinges on both doors. Two 20X20 filters nearest the camera, a side walk thru door and the far wall will be hinged to allow for body parts to be brought in and out, doors will be sealed with weather strip foam. Oh, i ordered an additional fan identical to the one i have so will have plenty of air flow, they mount in the far wall/door bottom. Hopefully i'll have it done Sunday as i'm working Saturday.

Re: Rat repair.
 

Nice job Mike, sucky about the back man hope you feel better. I thought we'd need 2 fans for our booth also but one set to high did a great job.

Re: Rat repair.
 

You guys are getting me to want to build my own booth and spray something!!!! Can't wait to see more Mike! Hope the back heals up!

Re: Rat repair.
 

I was feeling a bit better and getting board so i did some more, i did take today off work too... probably not the best move i ever made as i have two more work days to go. :lol:

Got a tarp under the booth and started the plastic on 2 sides and the top, pulled the plastic under the walls to the inside and tapped up on the bottom and door opening, also the large door is covered.

I'm kinda surprised at the duct tape i bought while at Harbor Freight, its some really sticky stuff!

Re: Rat repair.
 

Intently following along this is great!! I need to do the rockers and floor in mine and learing a lot from your thread.

Re: Rat repair.
 

With the exception of adding the plastic on the floor the booth looks to be done, side door is operational its right to the right of the filters, fan and filter installed on the large wall door, simple latches to keep it tight to the weather strips, i had to pull the blue tarp out from underneath as it was interfering with being able to swing open the big wall door. I got that second fan yesterday but not sure i'll need it.

Still uncertain what air flow is necessary, don't want too much or too little. Right now with the fan on high i can feel a draft on the back of my hand when standing in the center of the booth

Back is still a little out of whack so not doing much, another chiro trip tomorrow in the works..

Re: Rat repair.
 

Good job Mike way better than what we did for our frame painting.

Re: Rat repair.
 

Looks good Mike !!!! Too good to be temporary !!!! "LOL"

Re: Rat repair.
 

Looks great, Mike. Something you might want to rig up prior to using this fine contraption is the ability to switch the fan on and off from both the inside and the outside of the booth. That way the fan can be off when entering or leaving the box since you don't have an airlock. And lights... lotsa light! Being of advanced age, that's a must have for me (maybe not so much for you) but it sure helps to see spots you may have missed. Good luck!

Re: Rat repair.
 

So the switch is inside, the cord plug is outside, I was thinking i would just shut the fan off before i step outside but again i know not what i'm doing... So a little hand door or opening so i can reach in and turn the fan on or off??

Oh, I did give in and bought a HF spray gun and the mixable 2 part epoxy, I hope this nozzle size 1.4 is ok? I seem to recall something about maybe needing a 1.8 or 2.0?? Vic i recall you telling me what gun to get but when i was there i didn't have the info..

The spray can of epoxy i have will be used outside on the floor and rockers on a nice day.

Following Huggers advice on the paint forum i also bought a digital thermometer to make sure the metal is up to temp for proper adhesion.

One last thing, MY setup is as follows, compressor, pipe manafold, 2 inline milton oil/water seperators, then my hose reel. I moved the one seperator on the left in the last pic to having them both after the manifold, its an old pic but just wanted to show the manifold. i'm hoping that this setup is enough to prevent any fish eye problems?

Re: Rat repair.
 

Brett and Gary, I know its kinda fancy and probably could have tryed draping plastic around the area but if you were to look at what is on the other side of my garage you would insist on zero overspray.. LOL!

Re: Rat repair.
 

ok I will bite!!! Whats on the other side of the Garage???

Re: Rat repair.
 

Mike I think 1.4 tip is fine for epoxy. That is what I used. The 1.8 or 2.0 are more for the high build primers.

Re: Rat repair.
 

I agree, two part epoxies are a little runnier than the 2K primers so you can get away with a 1.4 tip. It just takes a bit longer to spray out the material so you'll want to mind the pot life if you squirt it on a warm day.

Re: Rat repair.
 

Question: I know there are different grades of light, which would be best for the booth?
T8 32-Watt Daylight (6500K)
T8 32-Watt Cool White (4100K)
T8 32-Watt Neutral

Re: Rat repair.
 

Due to the overwhelming response ( :) ) of my last question I went ahead and opted for the 32 watt Daylight because the lighting guy at Home Depot said they were the brighter of all the T8 bulbs in the display, I will compare them to what i have hanging on my ceiling and go from there..
