TL;DR
Two coats is always the answer for a uniform finish. Three coats when going dark-to-light, painting over red or yellow, or covering unpainted drywall. One coat is only acceptable on touch-ups of the same color.
The honest two-coat rule
- →Modern 'one-coat' paint marketing is misleading. Even premium one-coat-rated paint applied correctly looks better with two coats.
- →A single coat applied 'thick enough to cover' will sag, drip, and dry unevenly.
- →Two thin, even coats outperform one thick coat in every case.
When you need three coats
- →Going from a dark color (navy, black, charcoal) to a light color (white, cream).
- →Covering red, deep yellow, or deep orange — these pigments bleed.
- →Painting raw drywall: the first coat is primer/sealer, then two finish coats.
- →Going over oil-based paint with latex without a bonding primer (don't do this).
When one coat is fine
- →Touching up small spots with the exact same paint, same can, within 6 months of original application.
- →Spot-priming a stain before painting (the stain block, not the finish coat).
Common questions.
Not if you want a uniform finish that lasts.
