Supply and application of Amotherm Brick WB water-based intumescent paint for protecting brick walls from fire as required by the standards UNI EN 1364-1:2002 and UNI EN 1363-1:2001.
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 of the under-surface will vary depending on the type of surface to be treated. More specifically:

• new brickwork must be cleaned of any impurities and treated with Amotherm Brick Primer WB.
• existing brickwork with old paint must be thoroughly cleaned to eliminate any paint residues that are not perfectly bonded to the surface, and then treated with Amotherm Brick Primer WB.

The quantity of intumescent paint to be applied to the walls to be protected will depend on:

• the fire-resistance class EI
• the wall section (stratigraphy, composition)

For indoor applications, where there is damp and heavy condensation, we recommend applying Amotherm Brick Top WB acrylic topcoat.
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.

Guideline costs of materials and application (excluding scaffolding and any preparation of the surface):
• Amotherm Brick Primer WB: € 4,00/m2 (100 g/m2)
• Amotherm Brick WB paint: € 15,00/m2 (1kg/m2)
