A surface can be 'protected', making it easier to remove graffiti from it without visible damage. A number of products are available to seal the surface with a protective coating. The use of protective coatings can:
There are many variables and points for caution in the match of surface material, coating and removal products.

"My goal was to have a basic understanding of graffiti removal, products and techniques used. I thought the course was well structured and professionally presented through visual, verbal and multiple choice questions. It was easy to follow and understand although it often took repeated viewing of the videos to answer some of the questions which helped to reinforce the material. Level of Difficulty I have been a painter and decorator for the past 29 years and although l found the course very easy due to my knowledge and understanding of paint processes l did learn a lot about the technical aspects of graffiti management and the many factors involved to achieve a successful outcome. It is a course which requires the student to commit and participate in the learning process without involving endless hours of study. I would recommend this course to others who would like to learn the basic principles of graffiti removal." - John O’Sullivan Vic Wide Painting Service
