One coat can cover. Covering and looking finished are different things, and the gap between them shows up in evening light.
Why two
A single coat lays down unevenly — slightly thicker where the roller started, thinner where it ran out. You cannot see it under a ceiling light. You can see it when afternoon sun comes across the wall at an angle.
When one is genuinely enough
Repainting the same colour, on walls that are sound and were properly finished last time. That happens, and we will tell you when it does rather than charge for a coat you do not need.
When you need three
Going light over a strong colour, or any deep red or dark blue — those pigments have poor hiding power and need the extra build. A tinted primer usually saves the third coat.
Primer is not a coat
It seals and gives the paint something to grip. Counting it as one of your two is how people end up with a finish that looks thin in a year.
What it means for the quote
A two-coat job on prepared walls is priced by the room. If a quote is much cheaper than the others, the coats are usually where it was saved.
