The duties of a painter apprentice are to learn and perform painting techniques and other essential tasks under the supervision of an experienced painter. Typically, their responsibilities involve prep, such as masking, sanding, and laying drop sheets, and then applying paint under the direction of a supervisor. Other responsibilities include caulking, finishing, and touch-up work. After you gain experience and skills through training and instruction, you can become a journeyman. Qualifications to be a painter apprentice vary, but often include a high school diploma or GED. Some prior experience in painting or construction is useful.
