Buying Guide
- Odor-blocking mechanism: Look for primers labeled as odor-killing, odor-blocking, or mold-killing. Some products also act as sealants to prevent odor bleed-through from previous finishes.
- Surface compatibility: Confirm interior suitability for surfaces such as drywall, wood, plaster, concrete, masonry, and metal. Some formulas perform better under oil-based or water-based topcoats, so plan accordingly.
- Dry time and recoat window: Short dry-to-touch times and quick recoat intervals speed up projects, especially for large spaces or tight schedules.
- VOC and odor levels: Low-odor and low-VOC options reduce indoor air exposure during application and curing. Consider a product with low emissions if occupants will stay indoors during remodeling.
- Mold and odor coverage: EPA registration or mold-killing claims provide additional assurance for damp or previously moldy areas. For kitchens, bathrooms, or basements, prioritize mold and smoke odor control.
- Topcoat compatibility: Ensure the primer is compatible with the final paint or sealant you plan to use. Some products are designed to work under all paints and clear finishes, while others are optimized for specific topcoats.
- Application method: Sprays offer fast coverage for molding and corners, while brushes or rollers suit large wall surfaces. Consider the project size and access when choosing a product form.
