AMOTHERM WOOD 450 SB
Supply and application of Amotherm Wood 450 SB solvent-based fire-retardant paint, so that wooden claddings for walls and ceilings comply with European fire-reaction rating class B-s1, d0 (EN 13501-1). The fire proofing treatment must be carried out by spraying or brushing, or by using a roller, a curtain coater or 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.
Treatment consisting of Amotherm Wood 450 SB (component A + component B) and Amotherm Wood 450 Top SB (component A + component B)
Normal consumption: 300 g/m2 of primer + 160 g/m2 of topcoat – Total 460 g/m2
Cost of material and application by spraying including intermediate sanding between the two base coats and the topcoat (excluding scaffolding and any preparation of the surface):
• Amotherm Wood 450 SB: € 21,00/m2 (treatment with normal consumption)
