Factors influencing the selection of a paint system
Ease of maintenance
Customer’s expectation (durability)
Paint application methods available

Surface preparation available
Health, safety and environmental factors

The part of the document that describes the way the paint work is to be carried out, in conformance with the project specification and the protective paint system specification, as well as with the inspection and assessment specification
Corrosivity of the Environment
It is important to identify the corrosivity category of an environment since it will relate to:
Corrosion rate of the building material
Material selection of building products
Selection of proper corrosion protection methods for the building materials
ISO 12944-2 defines the classification of environments by corrosivity category
Specifications and procedures:
Specification: A document stating what we wish to achieve (To what quality level a certain piece of work must be carried out).
Procedure: A document explaining how we shall achieve the requirements in a specification (Processing instruction, check points, quality control).
