AMOTHERM WOOD WSB

Supply and application of Amotherm Wood WSB water-based intumescent paint and Amotherm Wood TOP WSB solvent-based topcoat (transparent treatment) for protecting load-bearing wooden structures from fire.
The fire proofing treatment must be carried out by spraying, brushing, using a roller or with an airless pump, applied at any height, either vertically or horizontally and/or at any angle.
The preparation varies according to the type of surface to be treated. More specifically:

 

• New raw timber surfaces must be cleaned of any impurities, particularly if they are made of exotic wood, and washed down with nitro thinner to eliminate any resin.
• Old, previously varnished wooden surfaces should be thoroughly sanded down to remove paint residues that are not perfectly anchored to the surface.

 

The quantity of intumescent paint to be applied to the various wood surfaces to be protected will depend on:

 

• the fire-resistance class required (R)
the section of the individual elements making up the structural framework to be protected
• actual conditions of load and light and span lengths
• the type of exposure to fire of each of the structural elements and their type (pillar, beam, etc.).
• the type of wood material (solid or laminated)

Assessing the protective measures to be taken and determining the thickness to be applied must be carried out based on the contents of the evaluation reports prepared in accordance with the methods laid down in standard EN 13381-7.

Costs of materials and application by airless spray (excluding scaffolding and any preparation of the surface):
• Amotherm Wood WSB: € 20,00/m2 (for 460 g/m2 equal to 360 g/m2 WOOD WSB
+100g/m2 WSB TOP)
• Amotherm Wood WSB: € 25,00/m2 (for 600 g/m2 equal to 500 g/m2 WOOD WSB
+100g/m2 WSB TOP)
• Amotherm Wood WSB: € 30,00/m2 (for 760 g/m2 equal to 670 g/m2 WOOD WSB
+100g/m2 WSB TOP)
