Supply and application of Amotherm Wood WB water-based intumescent paint (white 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 load conditions, 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 (solid or laminated)
Intumescent paint with environmental certification EPD according to ISO EN 14025 and EN UNI 15804 (environmental label type III) as required by Article 34 of the new Public Contracts Code defined by Legislative Decree No. 50 of 18-04-2016 and updated by Legislative Decree No. 56 dated 19-04-2017.
