Intumescent Coatings

Intumescent and Fire Retardant Paints and Coatings


Intumescent paints and coatings are basically a paint-like material which is inert at low temperatures – under 200 ◦C – but reacts with heat. As the temperature rises, during a fire event, the intumescent coating swells and forms a char layer that covers the steel. Created for structural steel and cast iron and are available with several different protection levels 30, 60, 90 and 120-minute fire protection.

Sometimes referred to as fire-proof, fire-resistant, fire-rated paint, the intumescent coating products listed on this page are available for interior and exterior use and come in a wide range of colours. Most of our intumescent paints can be applied by brush, roller or spray.

Your intumescent enquiry is utterly bespoke and needs to be treated by us individually. We are therefore here to help and support you to calculate how much intumescent paint you will need for your project meeting the specification required by building regulations – how much protection can be obtained with the listed coatings. What the differences are between Class 0 and Class 1 fire protection and much more.

Important fire test standards when using intumescent coatings on structural steel constructions are European Union: EN 13381-8 (this replaces national Standards in Europe) and United Kingdom: BS 476-20/21 (Commonly referred to in EU, Middle and Far East).
