Help Choosing Full Face Respirator for Lead Paint

I'll soon be prepping my entire house for painting. All trim is lead paint, in very tight condition. I'll just be scuffing.

I want to invest in a good respirator anyway, one that covers the entire face and eyes.

Looking at something like this:

No reviews, so hard to know.

Would this be good for dealing with lead paint?

Though I can't really comment on the lead removal aspect, I can say I am not familiar with that brand
I'd stick with AOSafety or 3M off-hand
A good full face from your local store should be between 100 and 200
That might seem spendy, but don't be cheap as your health is at stake
It should be comfortable, as if it's not you are less likely to wear it

Also, remember that it won't help if you don't follow the exact procedures outlined in the abatement courses, or from the EPA if DIY abatement is legal in your area

Scuff-sanding is a "belt and suspenders" kind of step. I would MUCH rather use liquid de-glosser (aka "Liquid Sandpaper") followed by an oil-base primer over sanding. Much less in the way of health hazard.

Nothing wrong with MSA respirators. The important thing is that it fits properly and seals against your face. It should have an N-95 rating. Next is to make sure you use the correct filter cartridges. They must have P-100 printed on them for particulates. Don't use organic vapor cartidges.

I got to go with that method for my recommendation. If that paint has lead it is atleast 30 years old. Lead paint was banned in the 70's, so I can't imagine there is too much gloss left.

Also remember you can absorb lead through your skin etc.. so wear gloves.

Best of luck, and liquid deglosser sounds like a great safe idea.

lead paint

There are a few issues with this approach. (We had a lead inspection and remediation in our house, so I'm passing along what we learned.) First, any lead dust will eventually go down to the floor, so you'll need a way to vacuum it up with a HEPA filter vacuum. Secondly, assuming you don't have any kids, the dust can still linger around for other kids to absorb. One partial solution is to use a spray bottle and mist the area as you are sanding. This will make a little wet mess, but will limit the dust. Also, you can't track the dust into other rooms. Where the blue booties, protective overalls, etc. and remove the clothing in that room. It really takes a methodical approach to cleaning, too. Another option -- depending on how many layers of paint there is -- is to strip the paint (Multi-strip is great, although pricey). MUCH more work, but if you already have 10 layers, like we have/had, then it's the right way to go. Otherwise new layers won't last long. Good luck.

Since when can you absorb lead through your skin?

If it were me, I'd get a respirator, but not a full face one that covers the eyes. I can imagine the inside of that thing just fogging up with humidity, and not being able to see out of it. Besides, any dust is going to stick to wet skin and can just be washed off at the end of the day.

I recently bought a new half face respirator made by 3M. It's good quality in my view. To check that it fits well, place your palm over the exhalation port (usually there will only be one in the middle of the mask) and exhale. The rubber face cover of the mask should inflate a lot rather than leak. Similarily, place both palms over the inhalation ports (usually two of them where the dust filters are) and inhale. The rubber face cover should shrink onto your face (due to the difference in air pressure) a lot rather than leak. That's how you test a respirator for fit.

Also, I don't know how real that threat of lead is. My understanding is that it's mostly a concern to newborn babies because the lead gets incorporated into the growing tissues of their bodies. Adults simply don't grow as fast, and so much less of the lead we're exposed to isn't incorporated into our bodies.

If you look at plumbers, it's common for them to be sanding the lead solder out of fittings and off the ends of pipes. And, that actually sanding a metal allow that was mostly lead, and creating fine dust to be inhaled without so much as a dust mask over their faces. I'm not saying that you should sand the lead based paint without any protection of any kind. I'm just saying that plumbers have sanded lead solder off of pipes for their entire careers and yet that seems to be of no concern whereas the lead based pigments in old paints are. Sumfin doesn't jive here.

Anyhow, I agree that SirWired's idea of roughening the old lead based paint with a chemical deglosser (like Liquid Sandpaper) is a much safer way to avoid lead exposure than sanding that paint directly.

(Does anyone know why no one's screaming bloody blue murder over the fact that no one's telling plumbers not to sand the old solder off of copper pipes and out of copper and brass fittings?)
