MEM08015
Apply protective coatings (advanced)


Application

This unit of competency defines the skills and knowledge required to spray pre-treatments and protective coatings when an advanced level of skill is required. It includes inspection and interpretation of the coating results using all current industry knowledge and test equipment.

Where application of basic single and two pack coatings not containing isocyanates is required unit MEM08014 Apply protective coatings (basic) should be selected.

Where the interpretation of technical drawings is required unit MEM09002 Interpret technical drawing should also be selected.

Where the selection and use of engineering measurement is required unit MEM12023 Perform engineering measurements should also be selected.

Where the selection and use of tools is required unit MEM18001 Use hand tools and unit MEM18002 Use power tools/hand held operations, should also be selected as appropriate.

No licensing, legislative or certification requirements apply to this unit at the time of publication.
