Surface must be clean and dry. Clean contaminated surfaces with a 50/50 mixture of Isopropyl Alcohol and water using a lint-free cloth.
Shake the primer well before use and apply a thin, uniform coating. Allow to dry for about 5 minutes at room temperature. For porous surfaces, two applications may be required.
3M Primer 94 can be applied with a brush, swab, flow gun, or roller.
Clean-up:
