Hi
When spraying a car shell in my garage last time the slight issue was the lack of air extraction. This meant that there were clouds of paint lingering in the garage. Whatever paint type is used there must be a lot of spray that ideally would be extracted.

Would one of these extractors with the relevant trucking make a big difference?:

It is the over spray clouds that are not being extracted that make the area I use for painting change colour as well!

Any advice on extracting the over spray would be great.

Cheers

This will do the job, we use these if we do a Smartrepair in the unit. Not sure if it will cope with the amount of fumes from a full hit though!

I am sure it will be better than not having one at all.

When I sprayed the last shell red, when I left the garage and looked back it was like a red smoke filled room.

When the description says " It can even be used to extract non-flammable fumes too! " I'd have my doubts personally.
Paint extractors/fans need a fully enclosed motor to be safe

Hi
Have you got a idea as to what may be a better option??

It's not easy for a home garage,anything that has come out of a spraybooth will probably be too large.

I actually use one that came out of a pot bank but it's 3-phase.

The OP might well be ok with that one from MM but there's a risk.I've seen what happens when spraybooths go up in flames when something goes wrong with the extraction system,you don't want to be in there when it does !

Leave the doors ajar would be the simplest option but not on a windy or wet day lol

As above put it under the garage door and close it as far as it will go, resting the for on top it will help a bit.

Hi Guys

The main garage door will be shut. Opposite the main door is the normal access door (standard size door) which leads to the garden.

Last time I left the door ajar during and after spraying. Although the end result was very good what was annoying is that the whole garage ended up red. Luckily I knew this would happen so sprayed the shell before he garage was finished.

This time I am spraying White and I do not want the overspray going everwhere.

What seems to be the issue is air flow. Last time the red clouds were moving around slowly as they were not being extracted, hence I thought an air extractor would be good.

The last thing I want though is a potential bomb on my hands.....

Is there a chance that with the paint fumes being flamable, that these fumes could/would be drawn into the extractor and alight the motor causing in essence a massive explosion?

Or is there a way around this?

Cheers

i would assume that 'proper' booths would have laminar flow systems ( like the charnley tent the joiners , sorry EFA orthopods , use during joint replacement surgery ...

as has been suggested there is a risk of a nay blower that's not intrinsically safe ingesting overspray that is flammable and going boom ...

To get air out you need air to come in also,so if your main door is closed but your side door is open you aren't pulling enough fresh air in to get the fumes out quick enough.

In all honesty if you're spraying 2K everything that isn't masked up is likely to get a covering

Thanks.

Does 2K primer spread / produce the same sort of fumes?

From what I remember last time I gave the shell 2 coats of primer and it did not make a mess.

This, but if you rig the fan to blow fresh air INTO the garage, therefore blowing the contaminated air OUT at the other end / side or whatever, you wont have to worry about it explodingeek

eta if the 'fumes' you're talking about are standard 2K, you REALLY shouldn't be in there without an effective respirator / air fed mask.

Hi Kim
So are you saying a standard fan placed the opposite side of the car to the door positioned to blow air over the shell whilst it is being sprayed should be enough to blow the fumes towards the open door?

The fan will blow the same amount of air wherever you put it, the only thing that will limit it is the size(s) of the door opening(s). As to whether it'll move the air fast enough to prevent the dust / overspray settling, that's something you'll just have to experiment with, I'm afraid. In my experience it will certainly help clear the 'fog' but you will probably still get 'dropout' all over the garage. This even happens in pukka spraybooths - they use a special scrape - offable coating which gets changed on a regular basis.

If you're blowing air into your garage be careful it doesn't blow crap and dust all over your new wet paint.
Proper spraybooths use filters over the inlets and outlets....talk to a friendly local bodyshop and see if they'll sell you a length for a few quid
