SPECIFICATIONS

& MATERIALS SELECTION

Following a site evaluation or inspection, DGC will generate and submit a site-specific work specification. The specification will outline the cleaning, preparation, application and inspection methods to be used to achieve the highest level of quality for every project.

Material selection is crucial as it will not only have to resist the demands of the corrosive atmosphere and environment, but will also determine the required method of surface preparation and application.

 

Important considerations in coating or lining selection will include but are not limited to:

  COATING    PROPERTIES  

  • Flexibility

  • Colour and gloss retention

  • Wettability

  • Drying and curing time

  • Appearance

  MAIN FUNCTION    OF COATING  

  • Deterioration control - corrosion, weathering etc.

  • Chemical resistance

  • Abrasion resistance

  • Waterproofing

  TYPES    OF SUBSTRATES  

  • Ferrous & Non-ferrous metals

  • Concrete

  ASSESSIBILITY    

  • Timeline

  • Equipment access for satisfactory surface preparation and application

  & OPERATIONAL FACTORS  

  ENVIRNOMENTAL  

  • UV exposure

  • Humidity

  • Temperature

  • Biological - fouling, mildew etc.
