Paint Safety - Two Part Polyurethanes Perfection & Ironsides

[marksa1458]

After hours of researching, I find that I am more confused than ever and am looking for some advice from folks that have used the two part paints.

I have been restoring this boat:



Since the boat is brown and has/had several damaged spots to the hull that I used epoxy/cloth to repair I wish to paint. I have rolled and tipped two boats so far. The Interlux Brightsides came out beautiful and the system 3 stuff came out ok.

Since this is a trailered boat and should rarely see more than a week in the water, I am looking at the Interlux Perfection -2 part or the Super Marine 2 part. In doing the homework on rolling/tipping these paints there is a lot of conflicting information regarding the appropriate safety gear, specifically respirators. If I do the paint work myself it will be in an attached garage with plastic sheeting around the work area to control fumes and keep dirt out.

In watching the youtube video of the application of Interlux perfection, the fellow doing the work has his face practically in the paint with no respirator what so ever. https://www.youtube.com/watch?v=gR58IdPAB1Y

the same for this video:https://www.youtube.com/watch?v=ItNo_pzdZJI

And in this video it they are using a full face shield: https://www.youtube.com/watch?v=ss6HvjRBaR0

In reading the MSDS sheets - they documents state that some situations may require a respirator. which isn't very helpful

In reading about the dangers of the isocynates that are in the paint there is also a lot of conflicting information out there - The seeming "general" consensus is that the only real danger with the isocynates in this paint are when it is atomized by spraying and for Roll and Tip application after everything is properly mixed the isocynates are trapped and generally harmless.

Can someone point me in the right direction provide advice for safety precautions with these paints - I certainly want a finish that is long lasting and durable but I don't want to poison the family either. There are certainly other options, such as renting a space, building a tent, etc... that I can pursue.

Thanks

The danger is magnified when shooting perfection you are atomizing large volume's of paint that become airborne. Rolling it out will not do that but the stench is still there so a good mask is in order the face shield is merely added protection and good measure.

It's been several years but I went through the same research. As I remember the consensus was if you were doing it for a living you want an air supplied suit, vented booth and full body protection. But, I compromised. The level of concentration is important so I used an exhaust fan to lower it and stayed up wind, covered every part of my body, changed filters daily and got the heck out of there as soon as I finished spraying. Isocynates get absorbed in the lungs, skin and surprisingly your eyes. If I had it to do over again I'd wear a Tyvek suit and a full face respirator and get a better fan. As far as I know you can get away with this in relative safety if you don't do it very often. Is it smart - no. In the end you are going to have to decide how risk averse you need to be. There are a lot of opinions out there and the safest way is well known but you won't find anyone that has researched the middle ground and can conclusively say if you do this, this and this you will be perfectly safe at a given exposure rate for a given amount of time. Hope this is some help.

If you roll and tip, the majority of the VOC's are kept to a minimum and basically just outgas while the paint is setting up and the paint is in the pot.
It is always a good idea to protect your lungs, skin and eyes, but if you have plenty of ventilation available while rolling and tipping and you work carefully, you should not have any serious health issues...unless of course you have certain allergies that may be aggravated by the chemicals in the paint you are using...
If you are spraying, that is an entirely different animal and you should take every safety precaution to prevent from literally being poisoned...airborne isocyanates will permeate through your skin and eyes and breathing it can be deadly...don't take unnecessary risks with your health because the whole point is to be around long enough to enjoy the fruits of your labors...
Good luck and have fun!

Thanks GT. All of your advice on my different posts has been most helpful!!! How long does the paint take to "outgas"

Usually till it dries or cures...in some cases it may take a few hours, in others it may actually take days or weeks for the paint to fully cure...depends on the chemical make up...
This is a strange way to tell, but I have found that it actually let's you know whether paint is fully cured or not...smell it, up close and personal, after its dried of course...if it still has a smell of chemicals, it is still curing or out gassing...when it no longer has that 'smell' to it, it can be considered cured...

Just removing the lid on Perfection or Alwgrip is fairly overwhelming


mast sprayed with SATA mini jet (big air brush ) so the bad things were minimal



Dont even get me started on how the recall was NOT handled 5 years ago








1. HUMIDITY is the enemy of the gloss , If dew forms overnight your screwed

2. The paint rolls well over the correct primer BUT completely different on the second coat AND IS FAR MORE PRONE TO RUNS

3. If you cause a problem and have to wet-sand the stuff is like a brick and takes forever

4. There are very specific instructions about drying time base on temperature

Tommays your work is amazing. Hope to duplicate your results!!!!
