Is Zinsser paint worth it?

Is Zinsser paint worth it? Zinsser paint, particularly AllCoat and Perma-White, is generally considered worth it for specific applications, though more expensive than standard paints. Zinsser is primarily known as primer brand, but its paints offer good value when you need multi-surface adhesion, stain blocking, and mold resistance in one product. Zinsser AllCoat Exterior and Interior are worth it if you need to paint difficult surfaces like wood, metal, masonry, and plastic without separate primer, as it saves time and provides durable weather-resistant finish. Perma-White is worth it for bathrooms and humid areas due to mold resistance. For standard interior walls where you already have good primer, regular premium paints from Behr, Benjamin Moore, or Sherwin-Williams may offer better color selection and finish for similar or lower price. So Zinsser paint is worth it when you have problem surfaces, need strong adhesion, stain blocking, or mold protection, but for normal walls, dedicated paint brands may give better value and color options. Many professionals consider Zinsser primers worth premium, and paints worth it for specialty jobs.
