Former house painter here. Do not sand the walls as another comment suggested. Waste of time. Decent quality paint should cover any other color just fine with two evenly applied coats. No need to prime, as it has presumably already been primed before being painted the first time, and primer is just a barrier for a surface that's absorbent, like raw drywall or wood (trim) so the paint doesn't just sink in. If it's a particularly garish color, you can use one of those "one coat" paint and primer in 1 products, but you'll still wanna do 2 coats.

I never learned sign aside from the alphabet and some basic conversation (thank you, water, drink, have a nice day) and I live/worked service in a city with a very large deaf community. When I worked in printing we would often have deaf/HoH folks come in and my supervisor would always get frustrated and hand them off to me. They were always super nice and it took a good bit of extra time to write out our communications but the appreciation I got from being willing to slow down and really try to understand what they needed was worth it.

I've used Aura quite a few times and the thing is you just have to make sure you put a real nice full coat on, using a good rag roller (not the fuzzy pink thin shit). If you're covering a similar color you can absolutely do one coat, but the way I learned with my dad is if you don't do two coats you didn't finish the job lol. Even with Aura you still wanna do two coats on the cut in because it'll be a little thin no matter what brush you're using.

And if it's red, you're always gonna have to do 3 coats to get solid, even coverage. I don't know what it is about red but it never wants to cooperate lol.

Big fan of Benjamin Moore paints though, that was what we always used.

For repainting trim before you get started it's good practice to sand shit down, but for drywall your employer was wasting your time and his money. Also, sanding between every coat? Just no. You sand down your spackle, you sand your trim primer, but sanding acrylic paint on drywall is absurd. Only do it on the trim if it was an absolute shit job before you showed up. If it was, you get rid of what you can, prime where you hit bare wood, then sand the primer before painting. Absolutely no need to sand between coats when you've got a good base. After that, there's no need to sand between coats because you're only doing two coats to get solid coverage. Paint will adhere to itself.

Painted for the better part of a decade.

ETA most walls don't get enough action to have to worry about long term adhesion, and the texture creates enough surface area to hold shit on to begin with. The biggest issue is when you repaint over trim that originally had oil based paint and weekend warriors like to slap a coat of latex (cheap) over it without sanding. That's what causes peeling. In my almost 10 years of house painting, I've never seen actual walls peel. I feel bad for the people that hired your employer.

If you did automotive paint that's a whole different ball game, but sanding between coats on whole ass sheets of drywall using water based paint is an exercise in futility, and would affect the finish negatively, if it affected it at all - which it wouldn't.

Okay so you post all this information for an AmA and conveniently leave out that you're responsible for what is arguably one of the first "memes" that ever existed?

Long live dancing baby.
