Surface fireproofing by application of finishes

The application of finishes is possible - varnishes, paints or saturators - when dealing with the reaction to fire of wood-based materials.

Several scenarios are presented according to the desired aesthetic criteria, the classifications to be respected and the context of end use of the product (inside or outside).

There are two categories of finishes:

  • The classifying finishes: they improve the reaction to fire of the support,
  • Non-decommissioning finishes: do not modify the reaction to fire of the support.

Technical characteristics

Depending on the nature of the substrate, whether it is put into service indoors or outdoors, and the desired appearance (translucent or opaque, film-forming or not)
Woodenha Industries offers a range of products specifically developed for reaction to fire issues:

• Intumescent: classical paints or varnishes, composed of an active base that protects the substrate, combined with a topcoat.
• Varnishes: can be classifiable or non-decommissioning.
• Saturators: non-film-forming and non-degrading
