Epoxy
8900 Mastic
Epoxy 8900 Mastic is a high-build, high-solids epoxy mastic coating engineered for industrial maintenance, asset refurbishment, and corrosion protection applications where abrasive blast cleaning may not be practical. This surface-tolerant, self-priming coating adheres exceptionally well to mechanically prepared steel, aged coatings, and tightly adhering rust, providing a durable protective barrier with excellent corrosion resistance and long-term performance. The high-gloss finish, low VOC content, and ability to be applied in a single coat make it an ideal solution for tanks, structural steel, industrial equipment, and maintenance projects.
Available in 10L kit sizes.

Intended Uses
Epoxy 8900 Mastic is designed for industrial protective coating projects where surface preparation constraints, maintenance requirements, or refurbishment conditions make conventional blast-cleaning difficult. The coating provides excellent corrosion protection on mechanically prepared steel and suitably prepared concrete while delivering strong adhesion to existing aged coatings and tightly adhering rust. It is particularly well suited to maintenance programmes, asset life extension projects, structural steel protection, tanks, process equipment, and industrial infrastructure exposed to atmospheric corrosion and wet service conditions. When overcoated with a polyurethane finish coat, it provides an exceptionally durable long-term exterior protection system.
Typical Applications:
- Structural steel protection
- Storage tank exteriors
- Process vessels and equipment
