Petrochemical Roof Refurbishment

Client: Petrochemical Plant

Industry: Petrochemical

Scope: Roof Refurbishment

Date: July 2018

Location: South Korea

Products: RL 500PF & RC 500GTC


The roofs of two petrochemical tanks were suffering from corrosion damage and required to be refurbished.

The client mentioned that these roofs are normally repaired every 2-3 years and that they were looking for a system which could offer them long-term corrosion protection.


The roofs had to be refurbished whilst the tanks were in operation; therefore grit blasting was not permissible.

There would also be no encapsulation of the roofs due to large costs and setup times; therefore coatings could only be applied by brush/roller.


The roofs were prepared using water jetting to  WJ-3 standards.

One primer coat of wet & rust tolerant epoxy RL 500PF was then applied, followed by one topcoat of highly chemical and UV resistant topcoat RC 500GTC.


The tanks were successfully refurbished whilst the tanks were in operation, which saved the client substantial time and cost.

Due to the success of the project, further roofs were scheduled to be coated using the same system for this client.
