How to spray interior floor - physical mechanics

So the (tentative) plan is to coat our interior floor with spray epoxy.

This is probably a stupid question, but how do I lay down successive coats of paint without walking on my previous work? Or do you only do as much as you can reach at a time (which would seem to imply a long time to do a bus)?

There must be a drone out there that can spray.


Don't paint yourself into a corner either.

wear socks or equivalent over your boots when you walk on the floor to avoid dirt or damage to the existing paint - be sure to wear a double organic particle mask, a cotton spray hood, coveralls taped to your gloves at the wrists and tape the legs of the coveralls to your boots - that is NASTY stuff to spray, so read up the WHMIS reports for up to date safety measures - the label on the can will give you the proper wait times for re-coating - unless that is going to be the final surface that you walk on, that material is really overkill for the job

So it's ok to walk on the paint you just laid down before it's cured, within the immediate recoat window?

Understood. And it makes me a bit nervous for good reason. Is the mask respirator sufficient, or is it something I should have supplied air for?

It is not the final surface. Insulation and wood going over the top. We're just going through a lot of work & effort to eliminate what rust is there, and I wish to absolutely, positively prevent any more from forming within any reasonable time-frame. I thought this would be the most durable, corrosion-resistant coating. But I'm all ears on what you'd recommend, Sledd. I know you have tons of experience in this area. I'd very much appreciate your advice.

Considering this is the one thing I'll never get to do a re-do on (unless I rip apart the entire bus, which aint happening), it's very important to me to do this as 'right' as it can be done. Just so you know my motivation in considering epoxy. I want it to be 'the best'.

I'd get rid of the rust as much as is practical, paint with one coat of Rustolium primer ( or competitor's product ) then 2 coats of Rustolium finish coat, cover it up with what ever flooring you plan on using - when your grandkids decide to remodel the old bus that grampa fixed up into a motor home, they will likely find a well painted floor in good condition long after you and I are long gone - the only rust there might be would have eaten through from underneath

I've just done pretty much exactly what Sleddgracer has described. After Ospho, a good rinse and scrub, followed by 2 days drying, I used Rust-Oleum 7769, Rusty Metal Primer followed by Rust-Oleum gloss black enamel.

I wore a 3-M mask with Organic Vapor cartridges so I didn't notice any fumes while I was painting, but then after I was done I took off the mask and could see that, with the windows open, I probably hadn't needed the mask, especially since I used a roller instead of spraying. But I still wore the mask the next two times when I painted anyway.

I didn't need any other protective clothing or anything. I got paint on me, but I ignored it until cleanup time then used paint thinner to get it off. So what I went through painting my floor sounds a lot better than Sleddgracer's description of the hazards of spraying epoxy.

I certainly hope so. That's the whole point. As I said in another thread, I intend to live in that bus for the rest of my life.

I'm sitting here just now watching Buster, my 13-month-old Staffordshire/Pit, chase his tail and chew on it for a while every time he catches it. He likes doing that a lot for some reason.

I see staying in one place as I age pretty much the same as Buster chasing his tail: just going around in circles and not getting anywhere.

you need to get this for Buster before he develops behavior problems -- Video
