Jotun Ultra Primer is a high-performance water-based primer designed for both interior and exterior use—especially on fresh concrete and masonry surfaces. It acts as a foundational layer for premium paint systems, enhancing adhesion and protecting against common wall deterioration issues.
Excellent Paint Adhesion: Enhances the bond between the wall substrate and the topcoat, helping paint last longer and perform better.
Anti-Efflorescence & Anti-Discolouration: Formulated to resist alkali attacks, efflorescence, and patchy discolouring that often affects newly-built or poorly prepped concrete walls.
Suitable for Fresh Concrete: Can be applied on newly poured concrete (after proper curing) and also works on slightly chalking or weathered old concrete surfaces.
Water-Based & Alkaline-Resistant: Offers easier application and is formulated to resist alkalinity and moisture penetration from substrates.
Interior & Exterior Versatility: Though often specified for exterior work, it is also suitable for interior walls under the right conditions, making it a flexible choice.
Green / Low Harmful Chemicals: Some regional product specs indicate it is formulated without certain harmful chemicals and may meet environmental/green-label requirements.
Ideal for new builds, renovation works or repainting projects where the substrate is fresh concrete or masonry.
Ensure substrate is cured and conditioned: fresh concrete should have cured adequately (e.g., moisture content under a certain threshold and surface pH below a defined limit) before application.
Application may involve one coat of the primer, followed by the selected premium topcoat system.
Use suitable application methods (brush, roller, airless spray) per surface condition.
Surface preparation is essential: walls should be clean, sound, and free from major defects for optimal performance.
The primer helps stabilise substrate surfaces, promoting better topcoat finish appearance and longevity.
It is not just a decorative coat but a primer engineered to address structural and material challenges (e.g., efflorescence, alkaline attack) that degrade wall finishes sooner than expected.
It supports “premium paint system” performance—by installing a strong foundation, the overall paint job is more durable, stable and visually consistent.
The versatility (fresh and old concrete) and the backing by a widely recognised brand in coatings make it a reliable specification choice.
For exterior walls (and sometimes interiors), where weathering, moisture and substrate quality are more challenging, this primer brings advanced protection rather than being a basic, generic primer.
