Performance & Benefits

Universal Primer-Sealer:
Bullseye 1-2-3 bonds well to a wide range of surfaces including wood, plaster, concrete, masonry, gloss paint, PVC and metal without the need for sanding in many cases — saving prep time and effort.

Stain Blocking & Sealing:
It effectively seals common stains such as grease, tar, graffiti, tannin bleed and mild water marks within the primer film, helping to prevent them from showing through your finish coat.

Rust Inhibition:
When applied over clean ferrous metal (e.g., iron or steel), Bullseye 1-2-3 forms a rust-inhibitive layer that resists flash rusting and promotes longer-lasting results under paint.

Mould & Mildew Resistance:
Contains a biocide that helps protect the dried primer film from fungal growth, improving performance in high-humidity areas such as bathrooms and kitchens.

Interior & Exterior Use:
Suitable for a broad range of substrates on both internal and external projects, including walls, ceilings, doors, trim and metalwork.
