Ultra Primer - Epoxy Primer for Concrete & Masonry
Ultra Primer is a high-performance epoxy primer designed for concrete floors in garages, warehouses and commercial environments. It delivers strong adhesion, seals the substrate and provides a reliable base for epoxy and polyaspartic coating systems.
Achieve professional-grade epoxy flooring results with Ultra Primer, the essential first step for any successful application. This 100% solids, two-pack, high-performance epoxy primer is specifically designed for priming concrete and masonry substrates. Formulated for superior adhesion, moisture tolerance, and chemical resistance, Ultra Primer provides an ideal foundation for subsequent epoxy coatings in commercial and industrial settings. Its low-viscosity formula promotes excellent substrate penetration and strong mechanical bonding, enhancing coating performance and longevity.
Although Ultra Primer is suitable for application on floors with limited moisture exposure, it should not be used as a moisture barrier; Ultrabarrier is recommended in those situations. Furthermore, Ultra Primer is a thickened primer that can fill minor surface irregularities and grout lines in tiled floors, providing durability and strong adhesion to damp concrete, even in areas subject to vehicle traffic.

APPLICATION INSTRUCTIONS
How to Apply Ultra Primer
- Ensure the concrete substrate has cured for a minimum of 21 days.
- Surface must be structurally sound, dry, and free from laitance, dust, oil, grease, and coatings.
- Mechanically prepare surface via diamond grinding or shot blasting. Acid etching is acceptable where mechanical prep is not feasible. Prime immediately after preparation to avoid contamination.
- Stir Part A thoroughly. Add Part B and mix using a power mixer for at least 2-3 minutes.
- Apply using brush, roller, or spray within the pot life. Avoid application below 5°C or in high humidity (>85%).
- Clean tools immediately with solvent before curing begins.

Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
