p2 mask, and thoughts on a powered respirator
FuryRebuild - 18/5/14 at 10:29 AM

So, I've not been able to play composites for a couple of weeks (work got in the way) and my cough seems to have more or less gone. When I'm cutting, flatting and sanding body-filler/glass I wear a p2 mask, but I'm losing confidence in it. I have a goggles/mask combo, but it's not very good - it's more or less a cloth filter and I struggle to get a seal. I also have a good P2 mask that does get a good seal, but then I struggle to get safety eye-wear that also fits well because the goggles but against the mask. I am reluctant to use wrap-around glasses for anything but the lightest of jobs after I was grinding with a set and got a piece of metal in my eye, where it went in under the bottom of the glasses. No harm done, but it was an uncomfortable couple of days while I got it sorted.

When I need to spray high-build (not done that yet) I'm acutely aware of the health-risks of spraying 2k without the right protection. For those that don't know, 2k sets regardless of being in air or not - breathe the paint fumes in and you are in essence, breathing vaporised glue into your lungs. I have bought a P3 mask for that (from screwfix, it's local) but I also use it when I'm working a lot with poly resin because it keeps the styrene fumes at bay.

So, my question to the group is ... has anyone used a powered, respiratory mask with a full face visor? If so, anyone know of a supplier that isn't going to lighten me by £300?

So, mask advice? Also, anyone got any horror stories to share?

If your gonna spray 2k I would say go for the very best protection you can afford - even if you have go skint to get it .
We had a guy who used to come in where I work to do small repairs and spray jobs - with 2k - and I never saw him use more than a basic filtered mask.........he dropped dead suddenly a couple of weeks ago , a fit and healthy 31 year old.......

I bought a diaphragm compressor (nice little devilbliss one. Actually very heavy) for £20. Length of hose, cost me about a tenner, and then I got a face mack off the bay for another tenner. Ex MOD type of thing. Connect together=nice air supply.

good friend uses a cheapo grinding type mask http://www.toolstation.com/shop/p53860
with foam strip to form a basic seal around his face, and uses a similar setup. The positive pressure keeps the nasties out very effectively.

getting it wrong with 2k will kill you fairly quickly - you will start to feel wrong in time with the curing time you've set. Dropping dead outside of that can be any manner of surprises - aneurysm for instance.

I'm aware that all the grinding and sanding i'm doing does release a lot of glass and bog dust, and I don't want to store up long-term lung problems ... not many hobbies are worth that. My half face masks do give a good seal, but then are useless with decent quality goggles. Similarly, my goggles/mask combo is only a cloth filter kind of mask and not working well for me.

these guys sell a full face mask which is where I'm leaning now - I can swap P2 and P3 filters to my heart (and lungs) content. They also do air-fed masks which I can pair up from my compressor - should then all be fine and dandy. My compressor is in a different workshop to the painting.

Stupid question - but do you have any facial hair? We use P3 masks at work when go into certain areas and before we are allowed, we are face fit tested and must be clean shaven or else it will compromise the seal.

Second that, I've just been fit to fit accredited from the bisf for work as we sell and fit all types of mask. I would not use anything less than a P3 for what you are doing, also if there are fumes and chemical involved then you may need an a1 or A2 cart as well as the p2 or p3 will only protect you from practical of solids.

For the cost of the it's not worth the rust esp when you realise that the traditional masks ffp2 ffp3 etc can only be worn once for a maximum of 1 hour and it you break the seal, even just 5 minuets from putting it on they have to be thrown away.

The force 10 mask is a good choice.

If you going down the compressor route be carefully and make sure the air intake is filtered

I just thought I'd give some feedback to everyone who chipped into this thread - I had a good chat to Matt from Protective Masks Direct yesterday, and I settled on two masks - this air-fed mask
for spraying, and a compact dust mask which is designed for wearing with goggles, so now all is good.

I use an air fed mask with 2k, run from a compressor in the garage, which is 15m, and generally upwind from my painting shed. Not cheap, cost me £120 I think, off ebay. It's never been used.
Wish I'd bought one years ago even for celly, it's great. 2k, not worth the risk
In my mind there's nothing heroic or brave painting 2k without the proper kit, just plain stupid
