Any thought s on spray masks, if I use two pack will I need air fed. It will be for one project only so don't want too spend upwards of £200 they seem to cost. Second hand worth looking at? Any comments please.

I got a second had devil air fed mask, paid just under £100 for it and it's looked like new, another £40 on new filters and it was ready to use. Remember you would be better off getting a three stage filter for it as well to keep water and oil out of your air since you will be breathing it.

An air Fed system should always be used with 2 pack paints, don't believe the suppliers that try to sell filter masks for 2 pack, they ARE NOT suitable! Neildisco is correct breathing air contaminated by water and oil is not good it can cause pneumonia!! Be safe out there. Kind regards. Chris

Are you going to be using it every day for the next twenty years or so?
If so yes. Get the best darn mask the japs can create.
If your using it once and maybe again in ten years or so get a large hanky and open a window. 20 B&H a day will do you more harm.
If your asking someone else to do it; get the good mask, wrap them in cling film and get them to pull the trigger via a string from the next county. Coz when there 95 and get a head cold Mr claims direct will be knocking at your door.

Ok, we are now in the realms of don't know wtf your talking about, I know nothing of spaying. Was told 2 pack is the one, I was going to use cellulose as its not so toxic maybe any paint sprayer could give me some pointers.
2k is good but usually because it contains isocyanate; which has a high chance of giving you long term damage. asthma and allsorts of bad stuff.
some people have tried making 2k without isos in them.. to make them safer.
you can buy 2k filter masks which people use.. but it's not recommended.
would you or a back street sprayer get away with it? maybe..
think of it like asbestos.. you could breathe that in and be fine for years then one day.. well, you wished you just paid a few hundred to a guy.

Thanks for that, whats the thoughts on cellulose.

Cellulose is becoming difficult to obtain thanks to the EU. I can only get industrial cellulose from my local paint shop! Its the same thing but the colour choice is limited! Get it if you still can! A good quality twin filter mask is all you will need to be safe! Good luck kind regards. Chris
i'm no sprayer. celly isn't as durable, was used for a longtime before 2k came around though
you take your chances. some have sprayed without masks, some with filters, some without full suits, etc
if i could get a really well ventilated place, i'd probably pikey it with a 2k filter mask if it was a one off or go for a non iso. wear a paper suit though.
upto you

I've used 2k a few times to paint my own vehicles.
Mask wise I just used a standard cartridge mask (mainly just to stop the smell getting up my nose)
No paper suit, bloody shorts and t-shirt in summer
My thinking is it's not like you're doing it day in day out with lots of exposure and will be fine.
On the 2k/cellulose subject, I used celly for my first re-spray as I was told it was easier.
Used 2k on the next and wouldn't go back now.
It does seem far superior, better coverage, longer lasting etc..
It's personal preference, so people are scared of it (rightly so) others don't give a **** (like me)

probably oil and water contamination in the tank
iso can absorb through skin, but it's not much compared to breathing it in

It cant be that bad on the skin. I hand brushed gallons of it on factory steelwork in the 80s. with nothing more than mi bib n brace overalls on.
I was allowed into the managers washroom though to scrub the crap off my hands at the end of the day. Its a sod to get out of your tash though

As I have never sprayed before what's easier to put right if I get any runs imperfections etc

You will get imperfections when you start. Its a steep learning curve and you will no doubt be removing more than you put on for a while.
Painting is the art of getting the right amount on without it falling off.
The right amount is 'the most you can' before surface tension gives way to gravity and it all sags into huge curtains. You would be surprised how much this is when the coat is even but as soon as the coat becomes uneven on a vertical surface the peaks are not supported by the troughs and away it slips.
I would say two pack is more forgiving than anything because it has time to relax once on the surface so is a little less likely to powder. Paints that lose their thinner as it leaves the nozzle tend to be harder to get a good finish fir the novice as they find it seems to dry in mid spray.
Dont let the first time you squeeze the trigger be on the car. Have a play. Get used to the flow, speed and pressure needed to get an even wet coat.
Practice and play with paint consistency. Remember only DIY paints at B&Q are designed to be used straight out of the tin. Pro paints are manipulated by the sprayer to individual circumstances.
Once you have a bit of confidence start priming the heap again and again until you become good at it. Primer is a lot easier to rub back than two pack.

You can always roller 2 pack paint if you use a good roller! We put it on the concord at Duxford! A lot of the car trade roller the 2k primer as you can rub it down smooth so it doesn't matter if you have a few lines in it. 2K topcoat can also be flatted alot if you take your time and put a few coats on, but don't rush it and put it on to quickly as it won't build and you need to let it flash off in between coats.
A cartridge mask will only last for about 10mins before the isocyanites will coat the carbon and not work anymore. But even £200 is cheaper than a set of lungs!
There is alternatives out there but they are just as harmful with the additives in them, isocyanites are mainly inhaled as its airbourne with the spraying but can also go through your tear ducts as it is attracted to moisture that's why it dries your lungs out!
Try and see if you can use someones spray area if possible!
Or I've got an old airfed you can use but you need to make sure your compressor will also run that and the gun and have good filtration as you will only be breathing the crap that the compressor draws in, so don't site it were your spraying!
