Troubleshooting
Stains are bleeding through after one coat.
Ensure the first coat had adequate dry time (45 minutes) and then apply a second, thin, even coat. Very stubborn stains or strong odors may require two applications.
Primer is not adhering to a glossy surface.
Verify the surface was clean and free of grease, oil, or wax before application. While sanding isn't required for adhesion, a thorough cleaning is critical. Ensure the product was well-stirred.
Strong odor lingers after application.
Ensure the area is thoroughly ventilated during and after application. The odor will dissipate as the primer fully cures. Maintain airflow for several hours.
Tools are difficult to clean.
Shellac-based primers require specific solvents. Clean tools immediately after use with denatured alcohol or an ammonia and water mixture (50:50). Do not let the primer dry on tools.
