The ranking value for this specification would be:
|
Primer |
Barrier (1) |
Finish |
|
Epoxy = 2 |
Epoxy = 2 |
Polyurethane = 3 |
|
Zinc Rich = 3 |
MIO = 2 |
Thickness = 2 |
|
Thickness = 3 |
Thickness = 3 |
|
|
Sub total = 8 |
Sub total = 7 |
Sub total = 5 |
Giving an overall ranking of 20
Note that in this specification although 2 barriers are specified it is treated as a single coat of 250 microns to avoid double counting the resin and MIO.
