1-2-3 Primer Sealer Stain Killer
Designed for interior and exterior surfaces, Zinsser Bulls Eye 1-2-3 Primer Sealer Stain Killer bonds to glossy surfaces without scuff sanding and performs well at low temperatures down to 35°F. This makes it suitable for challenging exterior substrates like previously painted surfaces, glossy finishes, or areas with light mildew and stains. The product’s stain-blocking properties help prevent bleed-through from water, smoke, and tannins, providing a stable base for topcoats. Application and recoat times are typically straightforward, supporting efficient project completion across colder or humid days.
All Surface Primer
Zinsser Bulls Eye 1-2-3 All Surface Primer is versatile for interior and exterior use on drywall, concrete, wood, masonry, metal, and glossy or difficult surfaces. Its water-based formula seals uniformly and sticks without sanding. Drying time is relatively quick—touch dry in about 30 minutes, recoat in 1 hour—and it covers up to 100 sq. ft. This primer is especially helpful when you’re dealing with newly exposed substrates or surfaces with previous stains that need robust sealing before painting.
Plus Spray Primer
Zinsser Bulls Eye 1-2-3 Plus Spray Primer provides interior/exterior performance in a convenient spray format. It works on new or previously painted drywall, concrete, wood, masonry, metal, and glossy or difficult surfaces. The oil-based formula ensures strong adhesion and uniform sealing, especially on challenging substrates where brushing or rolling is impractical. Drying times are rapid, aiding quick topcoat schedules for exterior projects requiring fast coverage and consistent results across large surfaces or detailed areas.
Water-Base Primer and Sealer
Zinsser 02244 Bulls Eye Water-Base Primer and Sealer is a reliable choice for interior surfaces and many exterior substrates where water-based formulas are preferred. It provides low odor and strong stain hiding on dark or porous surfaces and dries to the touch in about 30 minutes, covering up to 100 sq. ft. per quart. This primer is well-suited for homeowners seeking a low-odor option with solid performance on lighter exterior projects or on surfaces sensitive to solvent odors.
Glidden Total Exterior Paint & Primer All-in-One
Glidden Total Exterior Paint & Primer All-in-One is designed for outdoor use on properly prepared exterior wood, brick, masonry, concrete, weathered aluminum, weathered vinyl siding, and primed metal substrates. It resists fading, cracking, and peeling, offering excellent hide and coverage in a single product. This makes it a practical choice when a combined paint and primer solution is desired for faster outdoor projects, with durable color retention in exposed environments.
Ultimate White Paint & Primer In One
EVOLVE Ultimate White Paint & Primer In One combines primer and finish in a single product for exterior and interior use. Available in multiple sheens suitable for walls, trim, or doors, it offers one-coat coverage, good hide, low odor, and low VOC. This option is suitable for projects prioritizing speed and simplicity without sacrificing performance on exterior surfaces, particularly for light to medium repainting tasks or projects requiring fewer product steps.
Smart Prime Water-Based Primer/Sealer
Zinsser qt White Zinsser Smart Prime Water-Based Interior/Exterior Primer/Sealer delivers stain-blocking resins with a focus on adhesion to glossy surfaces and resistance to mold and mildew in dried film. It is suitable for exterior surfaces where a low-odor, water-based option with reliable blocking and bonding is preferred. This primer helps create a uniform base for topcoats while reducing the risk of bleed-through on challenging substrates.
Buying Guide
- Surface compatibility: Exterior projects may involve wood, masonry, brick, siding, or weathered substrates. Choose a primer designed for exterior use on your material type (wood, masonry, metal, etc.).
- Stain blocking vs. adhesion: For projects with tannin bleed, smoke stains, or water stains, select a stain-blocking formula. For glossy or hard-to-stick surfaces, a product with strong adhesion properties is essential.
- Water-based vs. oil-based: Water-based primers offer low odor and easy cleanup; oil-based primers typically provide stronger adhesion on challenging surfaces but require solvents for cleanup and longer cure times.
- Drying and recoat times: Shorter drying times help speed up exterior projects but consider the weather window to avoid rain or dew during curing.
- Finish compatibility: If you plan to use a one-coat paint-and-primer product, ensure the finish matches your desired sheen and durability for exterior conditions.
- Coverage and substrate conditions: Some primers cover up to 100 sq. ft. per quart, but rough or porous surfaces may require more coats. Assess your substrate texture and prior coatings.
- Odor and VOC considerations: For occupied spaces or homeowners sensitive to odor, water-based and low-VOC options are preferable, especially in enclosed or poorly vented areas.
- Application method: Brush, roller, or spray options can influence product choice. Spray primers can speed up large exterior surfaces but require ventilation and masking of surrounding areas.
- Maintenance and durability: For sealed outdoor surfaces, consider primers that pair well with durable, fade-resistant topcoats to extend color life in sun and weather exposure.
