Primer does three jobs: it helps paint stick, it seals porous surfaces so paint dries evenly, and it blocks stains from bleeding through. You do not always need it, but the situations where you do are predictable.
Always follow the manufacturer's label for ventilation, drying times and compatible topcoats. Oil-based and shellac primers have stronger fumes, so wear a respirator and ventilate; see our safety page.

FAQ
- Do I always need primer?
- No. Clean, sound, previously painted walls with a similar color often do not need it, while stains, new drywall and glossy surfaces usually do.
- Can I tint primer?
- Many primers can be tinted to a gray shade close to your topcoat, which can improve coverage with deep colors. Ask the retailer or check the label.
- Is paint-and-primer in one the same as primer?
- It combines both functions in one product, but it is not a substitute for dedicated stain-blocking primer in problem areas.
- How long should primer dry before painting?
- Follow the product label because times vary by primer type and conditions.
