Important Information

Advice and recommendations through Dulux SpecMap

SpecMap provides an indicative top coat powder coating specification based on the atmospheric corrosivity data for the project. We always recommend you to call our Advice Line to confirm your project specification, especially for commercial projects.


The atmospheric corrosivity zone indicated by SpecMap can be superseded for some commercial projects, eg airports and manufacturing sites, due to localised influencing factors such as:

  • ●  Levels of atmospheric pollution including salts, dirt, and grime that can all accumulate over time
  • ●  Winds carrying airborne debris that can cause erosive wear of the coating e.g. sand causing abrasion


Coating/product systems can be expected to perform as indicated on the product data sheets so long as applications and application procedures of the individual products are followed as recommended on the appropriate product data sheet and are also maintained within the Dulux recommended Care and Maintenance guidelines.


Any recommendation provided by Dulux Powder Coatings through the SpecMap tool in relation to goods manufactured by it or their use and application for a project is given in good faith and is believed by Dulux Powder Coatings to be appropriate in accordance with the information entered.
