SikaFiber®-1218 PPM
SikaFiber®-1218 PPM is a monofilament microfibre made from 100% polypropylene, with a fibre length of 12 mm. It is used as an admixture in concrete and mortar to help reduce shrinkage cracking, improve durability, and enhance the properties of cementitious materials in non-structural applications.
SikaFiber®-1218 PPM Applications
Suitable for concrete and cementitious mortars requiring reduced shrinkage cracking, such as:
Concrete slabs on ground
Screeds and concrete toppings
Wall plastering and rendering applications
Precast concrete elements
Sprayed concrete and mortar applications
Extruded concrete applications
Interior and exterior applications
The product is suitable for non-structural cementitious applications and cannot be used as a replacement for structural steel reinforcement.

Mixing Method
It is recommended to:
Add the fibres together with the dry aggregates.
Distribute the fibres evenly throughout the mixture.
The fibres may also be added after the other components have been placed in the mixer, but additional mixing time is required to ensure uniform fibre distribution.
Do not add the fibres directly to the mixing water. sikafiber_-1218_ppm
Important Precautions
Use with good-quality concrete or mortar.
These fibres cannot compensate for poor-quality concrete or mortar.
Compatible with Sika concrete admixtures.
Do not use as a replacement for structural steel reinforcement.
