Section 12:
PROGRAMMING MAINTENANCE PAINTING
12.1
Definitions of Programmed Painting and Maintenance
Painting. Paint programming is a systematic planning process for
establishing when painting is required, what painting should be
done, by whom, at what times, and in what manner. Maintenance
painting is a vital adjunct to programmed painting. It is
defined as a field procedure for maintaining existing coatings in
an acceptable condition.
12.2
Components of Programmed Painting. There are three
basic components of successful paint-programming plans: plans
for initial design of the facility, plans for monitoring
conditions of structures and coating systems, and plans for
maintenance painting. Each plan must be prepared properly and
completely for the total program to be successful.
Programmed painting can best be implemented as a
computer program. This program will contain the initial design
data, data on the conditions of the structures and their coating
systems obtained from an annual inspection report, and
recommended maintenance painting schedules and procedures. The
latter should include cost estimates for each item of work so
that funding can be requested well in advance of the time it will
be spent. Cost estimating programs for construction work are
available in the Construction Criteria Base (CCB) (National
Institute of Building Sciences, Washington, DC) and proprietary
sources.
12.2.1
Initial Design. The design of both new structures and
their coating systems is critical to achieving maximum life of
each.
12.2.1.1 Structural Design. Structures should be designed so
that they are easy to coat initially and to maintain in an
acceptable condition. Common structural design defects include:
a) Contact of Dissimilar Metals. The more active
metal will rapidly be consumed by galvanic corrosion to protect
the less active metal. This includes contact of steel and
stainless steel.
b) Water Traps. Structural components that collect
rainwater corrode more rapidly. These components should either
be turned upside down or have weep holes of sufficient size and
correct placement drilled in them. Weep holes should be as large
as possible and placed at the bottom of the structure.
