When you paint with a roller, do you ”cut in the wall” first then roll, or roll first then ”cut in”?

I worked on a campus paint crew for two years in college, way back. I always prefered to do cutting first, then roll. Both on walls and ceilings. Learned from Supervisor it took less paint, not as many mistakes, and saves cleanup.
I never used the tiny 2–3” roller that some now use instead of brushes. It would take some experience to be on- point and assured, I would guess. Has anyone tried them?

Cut in then roll. Except I’d get my husband to cut in. I’m really bad at cutting in.

We have staff for that

I think cut in first is best.

I cut in first.

I have used the mini roller. It’s good for the ceiling line, not great for corners, since it doesn’t get all the way in there like a brush.

Cut in first, but it usually requires retouching after finishing the wall.

@zenvelo When people do roll first they don’t go near the corners and ends if they are going to cut in.

Cut in, then roll. Otherwise too much care and time are taken to not let the roller touch walls, ceilings or floors that you don’t want to get paint on. But cut I about 3” – 4” so there is adequate room.

My only real comment on that was the amount of paint used. I have done both and as far as paint go, if you roll first but can roll tight, you don’t use any more paint than if you cut 1st, and maybe less. In some cases you save time because you hit all the large areas then all you have to do it fill in where the roller can’t go, as mentioned by some others.

Isn’t that funny. Two different approaches. Good thing we don’t share a can of paint, I guess. We’ll have to discuss it over the dinner and drink, customary at the end of a job.

Cut in, then roll. Over the years I find I am less likely to accidentally roll into a surface that is not to be painted that color if I have a colored line to stop at.

Unless it is baseboards and trim, then I roll up to the woodwork, occasionally getting wall paint on it, then come back and paint the woodwork.

… You painted around a mirror bracketed to a wall?

I have, if there is not time to remove it, or the resident dweller doesn’t wish it removed or pay a little less because of the small cost included to remove and replace it. One would be surprised at things I have been forced to paint around. If it is a remodel or new construction, it is usually better because you are painting before there is baseboard, socket covers, door knobs, mirrors, light fixtures, etc. Plus there is usually no flooring so you don’t have to be so neat (even though I am) or wrestle with drop clothes.
