Supply and application of Monokote MK 6/s fire proofing plaster for the protection of reinforced and prestressed reinforced concrete structures from fire.
The fire proofing treatment must be carried out by application with a plastering machine, 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 structures must be cleaned of any impurities;
• existing structures 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 Monokote Mk 6/s fire proofing plaster to be applied to the various elements to be protected will depend on:

• the fire-resistance class required (R/REI)
• the section of each structural element and its type
• concrete cover values and type of reinforcement (ordinary and/or prestressed)
• actual load conditions
• the type of exposure to fire of each of the structural elements.
For indoor applications, where there is damp and heavy condensation, we recommend applying Amotherm Brick Top WB acrylic topcoat.

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 standards EN 13381-3.

Guideline cost of material and application (excluding scaffolding and any preparation of the surface):
• Monokote MK6: € 10,00 /m2 (thickness 10 mm/m2 - This amount is net of any application waste, which can vary, depending on the type of structure, anywhere from 3% to 30%).
