3.1.1 The lifetime of a coating applied to a new
construction may be influenced by several aspects which include coating
selection, application and maintenance scheme.
3.1.2 Use of a hard coating is the most common
practice in present technology. The effectiveness of a hard coating
can be achieved only if the manufacturer's technical product data
sheet and job specifications are carefully followed.
3.1.3 Multi-coat treatments with coating layers
of contrasting colours are recommended. The last layer of coat should
preferably be of a light colour in order to facilitate in-service
inspections
3.1.4 Coating performance can be improved by adopting
measures at the design stage such as the reduction of scallops, the
use of rolled profiles and ensuring that the structural configuration
permits easy access with tools and facilitates cleaning, drainage
and drying of tanks.
3.1.5 Where coating is supplemented by cathodic
protection, the coating must be compatible with the cathodic protection
system.
