On a domestic job, you would use paint, varnishes and wallpaper to decorate rooms. You would follow the householder's instructions about choice of colour, finishing texture and wallpaper patterns. For industrial projects, such as bridges or ships, you would remove old paintwork with abrasive blasting methods before applying new coatings using industrial paint spraying equipment. You would use a cradle or safety harness when working. As a trainee you will often be supporting more experienced colleagues and be expected to learn from them to develop your knowledge.
