⚡ At a Glance

Shellac-based exterior primer designed to bond to glossy surfaces. Ready-mixed white format speeds preparation and application.
Quicker repaint cycles – thanks to a fast-drying shellac base
Shellac-based formulations cure rapidly, forming a hard film that accepts topcoats sooner than many oil or waterborne primers. Fast surface tack reduction leads to shorter recommended recoat intervals.
Faster drying reduces downtime on jobs, allowing repainting to finish sooner. Ideal for schedules that cannot wait several days between coats.
Reliable bonding on glossy surfaces – with shellac adhesion properties
Shellac chemistry adheres well to smooth, non-porous substrates by creating a mechanical and chemical grip on glossy finishes. That adhesion helps subsequent paint layers cling rather than lift.
Strong bond prevents peeling and flaking after repainting, reducing the need for extensive surface preparation. Suitable for surfaces where sanding back to dull finish is impractical.
Stain-blocking performance – with ready-mixed stain-killing action
Stain-killing additives in the formula help isolate tannins, rust marks and common surface stains, preventing bleed-through into new topcoats. Coverage levels reported by users often allow heavy stains to be contained quickly.
Often seals stains in one coat, cutting preparation time and the number of coats required. Useful when covering tired or discoloured exterior substrates before decorating.
