Epirez Ultra High Build Epoxy Coating 733 16L
Ultra high-build epoxy coating for demanding concrete and steel protection
- Cures underwater for splash zone piling and marine infrastructure repairs
- 16L kit covers approximately 5.3m² at 3mm thickness
EPIREZ Ultra High Build Epoxy Coating 733 is a solvent-free, high-performance epoxy coating designed to protect and repair concrete and steel exposed to flow wear, chemicals and demanding service conditions.
The coating is designed for infrastructure assets, splash zone areas and industrial environments where a high-build protective system is required. It can be applied in a single spray application at 3 mm DFT or greater, helping reduce application time and labour requirements compared with multiple thinner coating applications.
Ultra High Build Epoxy Coating 733 can cure underwater and withstand early immersion, making it suitable for maintenance work on splash zone piling. It can be applied at low tide and continue curing under immersed conditions to provide ongoing protection to wharf piling.
The coating provides excellent adhesion to wet or dry concrete, high mechanical strength, abrasion and erosion resistance, and resistance to a broad range of acids, alkalis and solvents.

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.
