What are Shop Painting Applicators?
Qualification Procedure No. 3 – Standard Procedure for Evaluating Qualifications of Shop Painting Applicators
1. Scope
1.1 This standard procedure describes a method for evaluating the qualification of shop painting applicators whose primary function is to provide surface preparation and protective coating application services. However, the procedure may be applicable to a fabricating shop, shipyard, or other entity that applies coatings in the shop, even though providing coating application services is not its primary function.
1.2 The procedure encompasses shop application of coatings in the industrial and light industrial/commercial market.
1.3 In addition to the evaluation criteria outlined in this procedure, the qualifying agency should review the applicant’s financial status, performance history, and ability to do a specific project in more detail than required by this procedure.
1.4 This standard is intended for work at fixed, permanent facilities. For field painting work that involves the use of a temporary structure, evaluating contractors using SSPC-QP 1, “Standard Procedure for Evaluating Qualifications of Painting Contractors,” or an equivalent procedure, is more appropriate.
2. Description
