What the AI looks for in Primer Paint
- Base by problem
- Use shellac for smoke, odor and severe stains, oil for tannin and water stains, a bonding primer for gloss, and PVA or latex for new drywall. Primer base determines what it can actually seal and stick to.
- Topcoat compatibility
- Confirm on the label that the primer accepts your topcoat, whether latex or oil. Mismatches can cause poor adhesion or wrinkling.
- Tint for color changes
- Have the primer tinted toward the topcoat color, or use gray primer under deep colors. This cuts the number of finish coats needed for full hide.
- Cure before topcoat
- Follow the label's recoat time, and allow extra time for bonding primers to cure before stressing the surface. Bonding primers reach full adhesion only after curing.
Brands that matter
- Zinsser: Category leader in stain blockers, including B-I-N, Bulls Eye 1-2-3 and Cover Stain.
- KILZ: Broad range from drywall to severe-stain primers.
- INSL-X: Stix is a go-to bonding primer.
- Rust-Oleum: Primers for rusty and clean metal.
What to avoid
- Relying on paint-and-primer products over water stains
- Latex primer on bleeding cedar or redwood knots
- Shellac primer as the sole coat outdoors
Questions
Why does a water stain show through after priming?
Water-based primers can reactivate the stain. Spot-prime with shellac or oil-based primer first.
