Sikacrete®-213 F

Wet sprayed, or hand applied, specialist fire protection mortar

Sikacrete®-213 F is a one-part, cementitious, specialist fire protection mortar for wet spray or hand 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 (up to 4 hours is achievable).

  • Pre-bagged dry mortar mix.
  • Application by the wet spray process, or by hand. 
  • Minimal layer thickness to comply with fire regulations.
  • Does not contribute to the formation of smoke or toxic fumes during a fire.
  • Lightweight, low density and breathable system. 
  • Easily surface finished by trowel or wooden float.
  • >240 minutes fire resistance achievable.
  • Minimal rebound when wet spray applied.
  • High thermal and acoustic insulation.
  • Easy to maintain and repair.

Application steps

EQUIPMENT

Select the most appropriate equipment required for the project:

Substrate Preparation

  • High pressure water blasting system.

Mixing

  • Large quantities shall be mixed in a suitable forced action mixer. Small quanities can be mixed using a low speed electric single or double paddle mixer (<500 rpm).

Application

  • Wet Spray: All-in-one mixing and spraying machine or separate spraying machine and all associated ancillary equipment to suit application volumes.
  • Hand: Clean containers, plasterer's hawk and trowel.

Finishing

  • Trowel (PVC or wooden).
  • Sponge.
 

MIXING

Important: The consistency must be checked after every mix.

  1. Pour the minimum recommended clean, potable water quantity into a suitable clean mixing container / equipment.
  2. While stirring slowly, add the powder to the water.
  3. Mix thoroughly for at least for 5 minutes, adding additional water if necessary to the maximum specified amount, adjusting to the required consistency to achieve a smooth consistent mix.

APPLICATION

Strictly follow installation procedures as defined in the latest Method Statement of Sikacrete®-213 F, application manuals and working instructions which must always be adjusted to the actual site conditions.

Sprayed Application - Wet Spray

NOTE: Include light wire mesh as required.

  1. 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.
  2. 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'.

Hand Application

NOTE: Include light wire mesh as required.

  1. Place workable amounts of the wet mixed Sikacrete®-213 F onto a plasterer's hawk and apply onto the pre-wetted substrate with a trowel between the minimum and maximum layer thicknesses without the formation of voids.
  2. 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'.

Sprayed Application - Dry Spray

Dry spray application of Sikacrete®-213 F is possible, please contact Sika® Technical Service for detailed application information.

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 TOOLS

Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
