Projects Paint safety at home..is anything safe to spray ?

Been reading warnings about Acrylic Urethane paint..not good. I just need to paint engine bay, and later down the road door jambs. I have the Harbor Freight auto body paint charcoal mask with replaceable filters. is any type of paint safe to spray at home without having an freshair mask system ? When it comes time to have the body painted, I will send it to a shop with a paint booth, and someone who does this daily.
How bad is BCCC at home,...just asking ?

 

Get the Proper Auto Paint Respirator(like a 3M paint resperator)with the proper filters for the particular evil poison you are spraying

Do some research on filters

I use one even when im spraying rattle can rustoleum

I dont like hocking up rustoleum loogies, or shoving tissue up my nose to wipe out paint from my nose hairs

Decades ago, There was a kid next to my shop , sprayed DuPont Imron without a mask. He was coughing up blood. I always wondered what happened to that dude if he died young
.

 

For just doing jambs and engine bay I would get a full face respirator, inexpensive tyvek paint suit and gloves. All the toxins can be absorbed through your skin especially mucus membranes like your eyes so a half face respirator is only doing half the job. Lots of people will probably say a half face will be fine but it really isn't.

 

The 3m 6200 is my recommendation. However, if you can't spray with the doors open and plenty of ventilation, I would recommend rethinking. You absorb the chemicals through your skin and eyes. As has been discussed many times, you don't know how sensitive you will be until it's too late. If you can move your project outside to paint, I would.

 

I went to a 3m workshop a few years ago and one thing they did was to help with the proper fit of their disposable mask and my fit was effected by my beard. The full face fit better for me..

 

If you have a beard nothing but a fresh air mask is doing the proper job. Respirators will not properly seal against facial hair. You cannot get certified for respirator use with any facial hair.

 

I sprayed in a booth for years and had to adapt spraying in my shop at home. A couple things I do is, take my time, use low air pressure when it’s possible and I have some vents that will let my fan pull air through the shop when I’m painting, another thing is I use faster catalyst and reducer when I can especially on smaller jobs.

 

This might not help answer your question but I had to paint some robot cell parts for a customer and the only paint I could get to match was Sherwin Williams water based paint. I never sprayed water based paint and I didn't think I had the proper equipment to spray it. I used my cheapie HVLP gun and was surprised how nice it sprayed, laid down and how quick it set up. I used an industrial grade paint for machinery so I don't know how it would handle UV. I didn't add any hardener, spray it as it came out of the can, no thinning. It was a mat black so I don't know how a gloss would stay glossy, especially when exposed to the elements but might be worth talking to a paint supplier about.

BTW, I was told I didn't need a respirator to spray but I still used one. I don't have a spray booth, just spray in my shop. Also, there wasn't much of an overspray mess to clean up.

 

Supplied air and a full Tyvek suit is about the only safe way to do modern 2k paints.
I used to shave once a year for my annual respirator fit tests. When I turned 50, a quarter century ago, I failed the lung capacity respiration test. I retired two months later with no regrets. My only painting nowadays is air brushing One Shot, thinned with turpentine, using a booth that exhausts to the outside of my workshop.

 

Single stage enamel is less nasty than urethane. The hardener for enamel is where isocyanates come in. If you reduce and spray without hardener - cure time is longer - but the airborne chemicals are less.

Get a better respirator for whatever you spray

 

Bob;
Don't the water-based paints require a clear over the top, & aren't they the usual isocyanurate-hardened ureathanes?
Last I heard/read. Curious.
TIA.

I don't know much at all about the paint I sprayed. I just depended on what the paint store manager told me. I asked if I needed a hardener and what kind of protection I needed. He told me to spray it directly out of the can and that I didn't need a respirator just a dust mask. I used a respirator anyways

Again, this was paint for industrial applications so I do know how UV resistant it is.

 

Yes, for sure. The problem is that your body can not metabolize Isocyanates. So they collect.

Yep, I am screwed there.

 

Here’s what I use I wear eyeglasses only thing that works for me. I wish I had found these years ago.

 

Hey, unkl;
I know about the iso's & *my* life, was wondering about the life of the paint w/o any uv-clear. Hence my Q's & concerns. Just from what I've read about things, water-based is not the panacea that it's promoted to be. *If* everything's water-based w/o iso's & can last like past paints, + have the deep depth/shine, that's great. Otherwise, it's just a *little* less dangerous - in terms of painting-chemicals time-exposure. Which isn't saying all that much. Which results in trying to figure out how to deal w/the fumes blown out of a garage, when the house is sorta close, making sure wind puts the gar downwind, I guess, while keeping the cat & wife inside for a proper time. Anything else around gets fkd, I suppose... IDK, I may be overthinking this...

I use the same, and have for almost two decades now. It's great for use while grinding, too, as the metal particulates are caught in the filter, but the pre-filters need to be changed out more often...small price to pay for continued lung capacity.

The downfall is the mask needs to be replaced once the lens gets scuffed, etc., and they don't sell the lens piece separately. They do sell peel-away lens covers for use when painting (I have used those, and they are great), so those will prolong the life of the fixed lens a bit.

Any 2K product and I would use a fresh air supply respirator, no exceptions.

 

After many years of wearing filter masks in power plants the ONLY filters I use with anything..solvents, paint etc. is one for pesticides. It’s the only one I have found you cannot detect an odor of anything.

 

Paint suit
Full mask respirator
Gloves
Face sock
Ventilation

 

I get certified once a year they have you put on a 3M mask then shoot a real bad smelling smoke under your mask while reading a weird poem if you pass out or tap out because of the smell your done that why a called bullshit on the covid masks they don't work You're going to be fine spraying those small areas get a good 3M mask and if you can smell anything I mean anything it's not working then stop and tighten up your mask wear a suit there not that pricey. The only thing that will protect you 100% is a fresh air suit and hood be prepared to shell out some good money for it though good luck.

 

it’s banana oil vapor.

 

I know a lot of people here harp on CALI saying everything will cause cancer. It was a good attempt pushed to the limits by lawyers.
That said, think about what is happening. You are taking a liquid and spraying it in the air to land on a surface to dry or harden to a tough, solid shell. This is without taking into consideration what the chemical makeup is in that mist. Benign stuff ain't great. Water based isn't like breathing on a foggy day. It's fog with stuff that hardens into a hard shell too. When talking about hardeners, they are almost always poison. Read your Material Safety Data Sheet (MSDS). Understand what Aerosol is and how it can affect you.

 

They used to use banana scented vapor but now it some nasty #%&# stuff that is bitter.
I wore respirators half mask ,full mask and supplied air depending on the situation. I worked in the petrochemical industry for 20 years and at 3M for 22 years and was around some nasty stuff. A simple test for half and full mask respiration is to unscrew the canisters and block the intake ports with your hands and inhale. If you can’t get air in, you have a reasonably well established seal. You need to be clean shaven anywhere the respirator touches your face. Tyvak suits are reasonably priced, get one rated for chemicals and paint, tape the seam between your glove and suit, also do not reuse the respirator canisters, some are rated for up to 8 hrs or one days use however if you smell solvents the cartridge is done Stop and Replace. Use a HVLP gun and ventilate your work area. A couple box fans with a furnace filter attached to the suction side, a fan placed on each end of shop one blowing in and one blowing out works for me. If you have a heavy haze in the shop stop and reevaluate your ventilation.
Stay safe

Yes. A HVLP gun will reduce overspray and wasted paint

 

If you are betting your life...and you are, buy the good stuff not HF. Your life, your call.

 

After reading ths, I think I will getting a 3M half-or full face respirator with the 6001 cartridge filters and with the N95/P100 outter covers...any thoughts for improvement, beside a fresh air system ?

 

These are not recommendations on what to use and what not to use. Make up your own mind.
My father died last November at the age of 92. He rode motorbikes in his youth without a helmet. He rode road racing pushbikes in his youth without a helmet. He was a panelbeater from the age of 14 and worked as one his entire working life. In his 20s and 30s he worked building hearses and ambulances where bodies were custom made. The joins were leadwiped and ground down before final filing. He told me they used to able to see the lead dust floating around the workshop when the sun shone through the windows. Most were painted in enamel or nitrocellulose lacquer without the use of masks.
I used to help in his business from the age of 12 till I left school and did my apprenticeship with him. He ground body filler, sanded it, painted with lacquer, enamel and 2 pak acrylic enamel and NEVER wore a respirator or mask his entire life and when he passed away it was from old age without a hint of respiratory trouble.
The old bugger was bullet-proof.

 

@spanners , I knew several old guys like that. They lived long, hard, and died in their sleep at an age we’d all love to aspire to. Seems like nothing affected them.
Sadly, I’ve also know others who never made it out off their 20’s, who were never sick but were suddenly taken sick and didn’t last anytime at all.

Life’s a gamble, we never know what we’re going to get out of it or what we’re going to have to put into it.

 

What is the number of 3m crarcoal filter pack you use ?

This link will give a good description of cartridges, also if your paint supply person is knowledgeable they can give you a good suggestion, I don’t think you can wrong with 3M a little more $$s but…..

I painted my 26 RPU in a home built booth in my garage with a HVLP turbine spray system and a hobby air supplied air respirator. (Allegro full face coverage mask)

I sprayed RM Uno Acrylic urethane.
isocyanate paints aren’t something to mess with without proper protection.

There are details on my home built booth and everything else in the thread above.
