TL;DR
A primer-sealer is a first-coat product that both promotes topcoat adhesion and seals porous or problem surfaces—new drywall, spackled patches, wood tannins, smoke and water stains—so the finish paint lays down uniformly without flashing or bleed-through. Water-based versions handle fresh drywall and general work, while shellac and oil formulas block the toughest stains and odors.

Painters spot-prime repairs at minimum, since paint over raw mud always shows.
