Primer going on extremely thin

We are using a good (BM something or other) primer over a dark red wall. The first coat applied via roller goes on incredibly thin. I mean really really thin. I made fun of my wife for doing such a bad job, but then I tried and got the same result...

2nd coat covers it all up just fine.

Is this normal?

Was the paint stirred properly. If not a lot of the solids can be left on the bottom of the can making the rest of the paint go on thin.

Primer does not cover, it seals and provides a good surface for adhesion of the next layer - the paint. Paint is what covers the color beneath. FWIW, covering dark reds is difficult, may take several coats of paint. Tinting the primer first could have helped but this is simply not the most straight forward paint job which exists.

Why do you think you needed primer in the first place? Unless you were painting latex over oil, it was probably not needed.

Different primers have different jobs, some are for sealing the substrate while others are for stain blocking and often used to facilitate coverage. If solids are left in the bottom of the bucket it will affect coverage no what type of coating it is.

My wife purchased it at the paint store and I imagine they properly mixed it. We may not have used it for a couple of days, would it have settled that much by then?

We ended up using 2 coats of primer and 2 coats of paint. I wanted to tint the primer but we weren't sure on what color we were going to paint. 2 coats of primer was perfect, and turned the wall perfectly white, so we had a 'fresh' slate to work with.

Maybe it wasn't needed, but I'm still glad we did it, just wish 1 coat would have fully covered. Oh well.

Normally paint won't settle in a few days/weeks. It may have been the wrong primer for the job at hand. Not saying the wrong primer wouldn't work, just that it wouldn't do as good a job.
