On the job, apprentices learn to prepare surfaces, mix and match paint, and finish wood. They learn different techniques for applying paint or paper as well as the characteristics of different finishes. Apprentices often learn more techniques than those who learn their skills on the job. These workers start as helpers. They start with basic tasks like carrying supplies and erecting scaffolds.
Trainees quickly learn to do simple painting and surface preparation tasks.
At the same time they learn about paint and painting equipment. Within a few years, trainees learn to prepare surfaces for painting and paperhanging, mix paints, and apply paint and wall coverings neatly. Near the end of their training, they may learn decorating concepts, color coordination, and cost-estimating techniques. As trainees gain experience, they become full-fledged painters and paperhangers. The learning period for these workers generally lasts much longer than an apprenticeship program.
