Performance & Benefits

Universal Primer-Sealer
Bullseye 1-2-3 is engineered to prime and seal a wide variety of substrates — including wood, plaster, plasterboard, masonry, metal, PVC, fibreglass and previously painted surfaces — without the need for aggressive sanding.

Excellent Adhesion & Bonding
The primer bonds well to glossy or hard-to-stick surfaces, often eliminating the need for extensive surface preparation before decorating.

Stain Blocking & Rust Inhibition
It traps and seals common stains such as grease, tar, graffiti, tannin bleed and rust marks. When applied over clean ferrous metal, it provides a rust-inhibitive coating that resists flash rusting and aids long-term performance.

Resists Mold & Mildew
Contains biocides that help protect the dried film against fungal degradation, making it suitable for high-humidity areas such as bathrooms and laundry rooms.

Interior & Exterior Use
Suitable for use on exterior wood, brick, concrete, metal and interior plaster, brick, skirting and trim — making it a truly multi-surface primer.

Recommended Applications

• Interior walls and ceilings
