Effective formula blocks stains and seals porous surfaces such as wood, plaster and concrete. Quick-drying properties help shorten project timelines.
Stops stains showing through – Thanks to stain-blocking formula
Stain-blocking formulation seals affected areas to prevent tannin and discolouration bleed-through when topcoat is applied. The barrier reduces the risk of old marks reappearing after painting.
A clean, uniform finish is achievable without repeated sanding or extra stain treatments, so repainting looks more professional first time.
Improved paint adhesion – With multi-surface sealing action
Sealing action creates a strong bond on porous materials, improving adhesion for subsequent coats on wood, plaster and concrete. The primer prepares the substrate so topcoats key correctly.
Fewer topcoats are often required and the final paint lays out more evenly, saving time and effort during redecorating.
Faster project turnaround – Thanks to quick-drying, easy application
Quick-drying formulation reduces waiting time between coats, while a user-friendly consistency allows straightforward application by brush or roller. Suitable for both indoor and outdoor use.
Rooms can be redecorated more quickly with less downtime, making the primer well suited to renovation schedules and patch repairs.
