Sikacrete®-213 F
Sikacrete®-213 F is a 1-part, cementitious, fire protection mortar for wet spray application. Suitable for fire protecting all types of reinforced concrete buildings and civil engineering structures including tunnels. It contains phyllosilicate aggregates, which are highly effective in resisting the heat of hydrocarbon fires. The fire protection performance allows a reduced thickness of fire protection required compared to concrete. The fire protection layer thickness depends on the specified fire resistance.

EQUIPMENT
Select the most appropriate equipment required for the project:
Substrate preparation
- High pressure water blasting system
Mixing
- Suitable forced action mixer
Application
- Wet Spray - All in one mixing and spraying machine or separate spraying machine and all associated ancillary equipment to suit application volumes
Finishing
- Trowel ( PVC or wooden)
- Sponge
MIXING
Important: The consistency must be checked after every mix.
- Pour the minimum recommended clean water quantity into a suitable mixing container / equipment.
- While stirring slowly, add the powder to the water
- Mix thoroughly for at least for 3 minutes adding additional water if necessary to the maximum specified amount and adjust to the required consistency to achieve a smooth consistent mix.
APPLICATION
Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.
Important: Avoid application in direct sun and/or strong winds.
Important: Do not add water over recommended dosage.
Sprayed application - Wet Spray
Note: Include light wire mesh as required.
- Place the wet mixed Sikacrete®-213 F into the suitable wet spraying equipment and apply onto the pre-wetted substrate between the minimum and maximum layer thicknesses without the formation of voids.
- Where layers are to be built up, to prevent sagging or slumping, each layer must be allowed to harden before applying subsequent layers “wet on wet”.
Surface finishing
Important: Do not add additional water during the surface finishing as this can cause discolouration and cracking.
- Carry out finishing to the required surface texture using suitable finishing tools up to one hour after application dependent on the temperature and humidity.
CURING TREATMENT
Important: Curing compounds must not be used when they could adversely affect subsequently applied products and systems.
- Protect fresh mortar immediately from freezing and premature drying using an appropriate curing method, e.g. curing compound, moist geotextile membrane, polythene sheet, thermal blankets etc
CLEANING OF EQUIPMENT
Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
