Bare wood, MDF, and fresh drywall are thirsty, porous surfaces that soak up paint unevenly and telegraph patched seams. These aren't slick-surface or stain problems — they just need an all-purpose primer that seals the surface and gives a uniform base. Here are the best picks for new, porous surfaces, with each one's honest trade-offs.

Frequently Asked Questions
- Do I really need to prime new drywall and bare wood?
- Yes. Porous surfaces like new drywall, joint compound, and bare wood absorb topcoat unevenly, which shows up as patchy sheen and flashing over seams. An all-purpose primer seals the surface so the finish coat looks uniform and uses less paint.
- What's the best primer for a smooth finish on trim and doors?
- A sandable wall-and-wood primer like Sherwin-Williams Premium Wall & Wood sands to a very smooth base, which is ideal before a showcase topcoat on trim and doors. Water-based all-purpose primers like Zinsser 1-2-3 also work well and clean up with soap and water.
