There are no formal qualifications required to become a painter however there are
courses that will give you a qualification that will always be sought after by employers. Just to prove you know what you're doing. Experience is very important in your painting career the more you have the better. You could start up a portfolio of all the projects you have worked on which will show your abilities as a painter decorator to prospective employers. Sometimes employers will also offer you the chance to learn whilst you are working and maybe employ you on an apprenticeship scheme.
