Legend
- ------ = No Primer needed.
- N/R = Not recommended.
- * = Coarse sanding / grinding is mandatory to achieve good adhesion. It is also mandatory to perform an adhesion check on the area to be primed before applying coating.
- Where two primers are listed, choose one as desired.
- (1) For roofs exposed to sunlight, use BOTH U5677 and E-5320.
- (2) E-5320 Primer is used if coating system is used in water immersion service.
- (3) Self prime with a thin film of 4 to 6 mils.
