Paint the wall with a diluted first coat (about 20%), that's it. That's
what I've always done.

Indeed, it works fine.

I have a small improvement on it, which is to paint the wall with
water, give it a few mins to soak in, then paint with emulsion neat.
Its quicker, less messy, and the first coat ends up much denser. Minor
tho.
