Ultra Primer 12L – 100% Solids Epoxy Primer for Concrete Flooring Systems
Ultra Primer is a professional-grade 100% solids epoxy primer designed for concrete and masonry surfaces. Engineered for strong substrate penetration and superior adhesion, it creates the ideal foundation for epoxy flooring systems used in residential, commercial, and industrial applications across Australia.
Its low-viscosity formula penetrates deeply into porous concrete to strengthen the substrate, improve coating adhesion, and reduce the risk of pinholes or coating failure. Ultra Primer is commonly used in garage epoxy flooring, warehouse floors, workshops, retail spaces, and industrial flooring systems where long-term durability and strong bonding performance are essential.
Ultra Primer is moisture-tolerant and suitable for slightly damp concrete up to 5% moisture content. For concrete affected by rising damp or high moisture levels, Ultrabarrier moisture barrier is recommended instead of Ultra Primer.
Designed for Complete Epoxy Flooring Systems
Ultra Primer is not designed as a standalone coating. It is the first coat within a professional epoxy flooring system and is commonly used under solid colour epoxy floors, decorative flake flooring systems, and industrial epoxy coatings.

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.
