This standard operating procedure (SOP) covers the process for applying a primer sealer during a repair. Before beginning any repair, it is important to always wear the recommended safety protection required for the job.
PD-0701: Primer Sealer Application
The application of a primer sealer ensures maximum adhesion capabilities for the topcoat while helping to ensure a uniform color match.
Step-by-Step Instructions
- A technician should review a work order to ensure that all parts to be painted are present and repairs are understood.
- Clean the repair area with a regionally approved surface cleaner. Dry thoroughly with a clean towel.
- Mask vehicle according to PD-0300 VEHICLE MASKING.
- Tack off the repair area. For spot repairs, keep the primer-sealer confined to as small an area as possible. Look up the formula for the topcoat color and identify the recommended G-shade or Spectral Grey primer-sealer. Mix and apply Primer-Sealer according to the Product Data Sheet for detailed instructions.
- When using solvent basecoat color, if a second coat of Primer-Sealer is necessary, allow flashing to a uniform, dull appearance before applying the next coat.
When using waterborne color, ECS 8x or P565-318x Primer-Sealer, one coat application is recommended. If a smoother blend edge of the Primer-Sealer transition is desired:
Option#1- for waterborne basecoat color, melt the Primer-Sealer edge with the same solvent used in the sealer. For solvent basecoat color, a uniform finish blender may be used to melt in the Primer-Sealer edge.
Option#2- after the Primer-Sealer has dried thoroughly; lightly scuff the sealer edge with P800 – P1200 grade paper. - When recommended dry time is achieved, the Primer-Sealer is ready for the application of the basecoat color or single-stage color.
