Cement Polymer Composite Coating System for Reinforcement

C.E.C.R.I Karaikudi Method
CPCC System consists of a Primer Coat and a Sealer Coat

Advantages:
Simple to apply and the coated bars can be cut & bent. Cost effective.

Surface Preparation:
The Steel bars shall be cleaned by sandblasting to the near white metal.
