Far more than intumescent coatings



AITHON not only produces intumescent and reactive coatings for concrete, potted slabs and timber fire protection but also ensures specialized application through a team of approved applicators trained by AITHON. Furthermore, the company cooperates with IDF, which offers all complementary services:

  • Definition of any preliminary concrete restoration, when needed.
  • Adhesion/cohesion testing between rendering or plastering mortars, or old paints and the substrate to which they are applied, in order to verify that they are a suitable substrate for a fire protection coating.
  • Detailed cover survey and thermal map modelling, for a precise evaluation of the existing level of fire resistance.
  • Exact calculation of the quantities of AITHON products required for the fire resistance upgrade.
  • In situ verification and certification of applied thicknesses.
  • Issuance of a Fire Resistance Structural Appraisal according to BS EN 1992-1-2.

IDF is an independent fire engineering company with extensive international experience, particularly in the field of reinforced concrete.

Pioneers In Fire Protection

We continue to experiment

With over 30 years of experience and technical solutions tested by major
laboratories in the EU, United Kingdom, USA and Australia, we have resolved issues related to many different construction techniques. We continue to experiment, collaborating with manufacturers and universities in Sweden and in Australia, to meet requests from the over 25 countries in which we operate.

This helps us always to have an extra solution on hand when dealing with a specific project.
