This figure is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.

Static Mixers (Small volume quantities)
Mix with an electric single or double paddle mixer (<500 rpm) or using a forced action mixer capable of mixing 2 to 3 bags at a time. Add the recommended amount of clean water in a suitable mixing container.
Stir slowly, add the powder to the water and mix thoroughly for a minimum of 3 minutes. Add more water during the mixing time if necessary to the maximum specified amount to achieve asmooth consistent mix.
If necessary and before pumping, let the material stand to allow the air bubbles from entrained air to finish. Stir gently if required.
Continuous Mixer (High volume quantities)
The mixing ratio shall be determined using a pan test heating method or microwave technique (according to Austrian Standard) to determine the equivalent flowrate/m³ on the equipment. Contact Sika Technical Services for additional information.

Pumping and printing is usually a continuous process.
The application specifics of the extrusion and printing speed must be optimised between the mixer, pump, pump line length and printer head.

When printing, it is recommended to cure the finished printed element with a suitable Sika® Antisol® curing agent.

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