3 Preconditions for the execution of the paint work

3.1 Qualification

3.1.1 Companies contracted to apply protective paint systems to steel structures, and their personnel, shall be capable of carrying out the work properly and safely. Work requiring particular care with regard to its execution shall only be carried out by personnel having qualifications which have been certified by an approved body, provided no other agreements have been made between the parties concerned.

3.1.2 Where the contractor has a quality management system in operation, a quality plan shall be prepared by the contractor which includes his general standards of workmanship. A method statement shall be provided for each stage of the work.

The contractor shall show that he will be able to achieve the specified quality level at each stage. Evidence for this is, for example, given by the use of a quality assurance system in accordance with ISO 9001 or ISO 9002.

Unless otherwise agreed, the contractor shall provide the client with extracts of all execution and supervision standards given in his quality manual that are relevant to the specification.

3.2 Condition of the substrate

A protective paint system requires proper surface preparation, which depends on the initial and final condition of the surface. The respective requirements shall be specified in the painting specification and be capable of achievement.

Methods of surface preparation are described in ISO 12944-4. The prepared surfaces shall be assessed with regard to visual cleanliness, surface profile and chemical cleanliness, using the methods given in ISO 12944-4.

The requirements for the supervision of these aspects of the work, the frequency of assessment, and the location of the assessment work shall be agreed between the parties concerned.

If the condition of the surface differs from that described in the specification, the client shall be informed.

The temperature of the surface shall be without doubt above the dew point of the surrounding air, unless otherwise specified in the paint manufacturer's technical data sheet.

3.3 Health and safety and environmental protection

The applicable regulations concerning health and safety and environmental protection shall be complied with. See ISO 12944-1 and ISO 12944-8.
