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.

Key Features & Benefits

• 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.

Usage & Application Tips

• 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.

Why It Qualifies as a Quality Product

• 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.
