What is Epoxy Pipe Coating?
Epoxy Pipe Coating (also known as brush coating or spray lining) is a NoDig method of pipe rehabilitation where the inside of the pipe is coated with a two-component epoxy resin. The result is a new, smooth surface that protects the pipe from corrosion and leaks — all without digging.
🎯 When to Use Epoxy Coating?
- Old metal pipes with corrosion
- Pipes with minor cracks or leaking joints
- Pipes under floors, in walls, or hard-to-access locations
- Renovations where you want to avoid demolition
- Preventive protection of new installations
The Process
- Camera inspection — assess pipe condition and locate problems
- Cleaning — pipe is thoroughly cleaned using high-speed method
- Drying — pipe must be dry for good epoxy adhesion
- Epoxy application — two-component epoxy applied by brushes or spraying
- Curing — epoxy hardens (usually 2-4 hours)
- Final inspection — camera confirms coating quality

- Uneven application — check brush and pipe diameter compatibility
Conclusion
Epoxy Pipe Coating is a smart alternative to expensive pipe replacement. With the right equipment and technique, you can rehabilitate pipelines for a fraction of the cost and time — with 50+ years warranty.
