And finally the connection on the belt for the air hose has a familiar quick-detach tail but doesn't fit my quick-detach thingies as it seems to be a size up. I found that all the connectors that come with Aldi air tools are those slightly-bigger ones - they look like they'll fit, but they don't, so I've replaced them all with PCL equivalents. Also still no pics as my camera kept saying battery flat, despite charge-indicator showing full. Am thinking it doesn't like the cold perhaps. Was frosty down at barn tonight. I get the same with mine. It's getting on a bit, and it lives in the car most of the time. Frustrating when it switches one, does all the right things, then when you press the button it shuts down again with "Low Battery". |

That's interesting as I was in Halfords yesterday and they seemed to have the bigger ones on their SIP bits. Back of packet said 'export' in the description which probably means nothing. It should probably say Rectus 25 or PCL XF. This seems to be the two brand names for compatible parts that size |

If you have an air-tight sealed breathing apparatus, and use a manual 'snorkel' type air feed (such that is is lung-powered, with several meters of hose), 'vented' to breathable air (e.g. atmospheric), then I can see neither: - How the paint can be breathed in (as I say, air-tight mask) - How the external air wouldn't be breathable quality If its air tight - then fine - but how do you know that and how do you test it External air down a long pipe - Pretty sure it would be a breathable quality - I'm not medically trained but I'm pretty sure that you are asking a awful lot of your lungs to draw the air down the pipe - how do you specify a pipe of the correct diameter to ensure that you achieve the correct air flow rate - secondly it would require some type of a one way valve to prevent exhaled air being forced down the pipe that you are relying on fresh air from - sure it's achievable - but at what cost Has already stated it's not that expensive to kit yourself up properly - so why go taking risks with something that you think (in theory) will do job - If it was that easy a solution that's exactly what every trained & qualified paint sprayer would be adopting We have not even touched upon how you would manage a airline plus a air tube of larger diameter - getting them around the vehicle / panels without snagging / getting caught up and catching a panel that you have just applied paint to / condensation created within the sealed mask from your exhaled breath falling from the exhaust valve on to your newly painted panels etc - Its not has easy has you think it is but not that difficult or expensive to do it properly either maybe hes he's gonna test it in the bath under water! If he don't drown it'll be ok, if not,no sprayjob anyway 😁 |

I've got a hot tub air pump in an adjacent shed, feeding a loop of 25mm conduit around the garage ceiling with a T piece at each corner I can plug the face mask which has about 8 feet of similar hose into, loads of fresh air and positive pressure means no chance of breathing ambient air, the only problem is it is noisy.

Well am quite pleased this (hopefully last) airline fitting will mean I can spray 2K before the year is out. It's freezing just now and I know you're prbably meant to spray 2K at 50 degrees Celsius or some ridiculous temp that we never get in UK but as this is for chassis parts am not bothered about visuals. iirc cellulose apparently 'blooms' if you spray on cold/damp days. Mb 2K doesn't hardend properly. I don't know but only one way to find out. I actually have (cheap) infra-red lamp bought for heating painted parts and I just bought some very expensive replacment bulbs for it but tbh I cba setting that up just now. Will keep it for bodywork So yes this fitting.... it's a PCL quick-coupler body and has a male 1/2" BSP on other end. I will be screwing it into the ball-valve on the 2nd compressor and connecting airline from there to 3-stage filter. It was £6.95, inc P&P, and looks pukka with the little rubber band round it. Am still not sure if PCL and Vertex are brand-names or industry-standards but this has both stamped on it  PCL coupler to 1/2" BSP male |

You need to paint in warm conditions for 2K. 15 degrees plus ideally.
It won't stick to the panel properly or cure properly if you paint at lower temps. Get you infra red lamps sorted and do it properly. You have gone the whole 9 yards with all the PPE but are going to bodge the paint??

I've put the primer on in this cold weather and it seems to have stuck fine (Glasurit EP 801-72)  |

There is sticking ok and really adhering to the parent panel. Correct temps will get you the second option.
Done properly the paint will stick forever, done incorrectly it will chip off or flake/rust in the future.

It's also a good way to learn from my own mistakes |

So the weather is warmer and I have everything I need to start spraying 2K but one last question....
Once I've finished spraying (and not lifted my visor once) and exit the spraying area for the day can I clean my gun etc without the mask?
Also before starting. Can I mix up the paint with no air-fed mask?

No. Clean gun while still wearing your PPE.
You can mix paint without an air fed mask, but you should wear a 3M 06941 mask instead - so you might as well use your air fed one.

So I have all my gear ready and importantly a compressor to supply the mask situated well away from the painting area. I'm painting inside barn and mask compressor is about 20' outside the building. The hose from that compressor needs to enter the building at some point to meet my mask. No point using the door as I'll need to go in and out there are hose would stop door closing properly anyway. Barn just happens to have an opening, from days gone by, which was bricked up but I can still squeeze my hose thru between the stonework. It's obviously not air-tight but I am doing some mortar-work in there anyway so can reduce size of hole then was thinking seal it with mastic or something. I guess my question is 'how far do you need to go with this to make sure your air-supply isn't contaminated with isocyanates?'  |

You'll be breathing through filters right? 3 stage plus a coalescing filter on the air fed mask (think thats what my set up is anyway), so your mask should be supplying air good enough to live on, as the filters will be filtering out nasties.
Wind direction is always on my mind when I'm painting. My compressors are outside 1 side of the building and my fan blows out the other side. If the wind was blowing from the north west my compressor would likely be inhaling the fumes from the fan, most of the time the wind is going the other way so my compressor is inhaling clean air.

Yeh I think theres plenty of factors to consider there but it really just comes down to common sense. And yeh the carbon filters will filter out any trace nasties that do get through

Are we talking about nasties from the air-compressor tank (outside 'booth') or all nasties?  I was under impression that even with a good correctly-filtered air-fed mask you still couldn't risk having the compressor in the same area as the paint as you couldn't filter the isocyanates out of the air. If the filters can do that do I need to bother with a remote air-supply? I opened up a mysterious bit in the barn last night and am going to fix all the gaps in the mortar but leave just enough for the hose to come thru from outside  hope to have my mask-air coming in here somewhere

I don't categorically know the answer to your question but for me it was a case of doing what seemed to reduce the risk the most - for me that is having the compressor outside and as far away as possible from the exhaust fan and of course using filtered air fed mask.
When i look back i probably shouldnt be here - i used to work for someone (before i knew any better) and we used to use 2k in a workshop with no masks (at all), the door was rolled up a bit and a fan at the back of the workshop would blow some/most? of the fumes/overspray out...this was a so called professional outfit. Id like to have a word with him about it now. Absolute to553r. I was unaware of the risks at the time.

You are over thinking it.
As long as the compressor is pulling in clean outside air it will be fine. It wont hurt to seal up the hole around the hose tightly, but it's not necessary.
As Aaron states, you don't want the compressor downwind of the fumes but otherwise it's fine.

You know how I mentioned common sense... 😋
In theory a correctly specced carbon filter will filter it all out even if you had the compressor in the spray booth but clearly it's better to have it in as clean an air supply as possible from the start.

Thanks guys. Well I have finished my pointing work and just got a small hole left for the hose. Warm weather supposed to be on its way so expect some 2K to be going on this week. If I get work-related athsma now can't say I haven't tried to be safe  |
