Specifying intumescent paint coatings

Whilst intumescent coating products may look just like paint, they have an important function (i.e. passive fire protection) that makes their specification a much more involved process.

A correct intumescent coating system specification should include the following information:

  • The corrosive category
  • The steel section size, or the designated profile and dimensions of the member in question
  • The number of exposed sides that the member will have, for example a freestanding column will have four exposed sides, whereas a beam topped by a concrete slab or abutted against a wall will have three sides
  • The FRL that must be met, in accordance with the classifications provided by the NCC
  • The critical temperature or design load used by the structural engineer in their design
  • The steel preparation required
  • The intumescent basecoat and finish required
  • The top seal required
  • A product technical data sheet
  • Client details
  • Project details
  • Any other requirements, such as core-filling or meshing

The specification of intumescent paint coating systems is a highly specialised field requiring qualified practitioners in order to achieve compliance. Contact Swart & Sons for more information (or see the banner link at the bottom of this page).
