The painting works for the external concrete beam of a high-rise project should be done if you have no any other options to make the external view of your building looks amazing.
This was what happened, the client was so impatient and he wanted to finish the project before the deadline. So what we did is we proposed the paint system to paint the external concrete beam from 1st floor to 25th floor.
So, without further ado, here is the method statement.
