Title
General - How to repair broken parts
Introduction
Cyan acrylate or super glue alone may join broken parts only insufficiently. If the parts will be stressed, often the bonding breaks at the same point again.
The trick is to increase the bonding area by scattering glass sand alternately with glue onto it.
After the repair the parts are often significantly more stable than before.
The video shows how this works.

Conclusion
Low viscous cyan acrylate glue is better for this technic than the jelly like glue, because it sucks more easily into the gaps in between the glass particles.
Glass sand has the advantage that it is alkaline and therefore the super glue hardens quite fast. In principle you may add as many glass layers as you like to build for example reinforcement ribs or bridges. In addition you may fill layer-wise holes or cracks this way. Excessive material may be cut off using a scalpel. Also post processing by filing or sandig works fine.
The glass sand scattering technic is also working well to repair broken porcellain or ceramics.
Unfortunately not all plastic material can be easily glued. Especially with poly ethylene, poly propylene an Teflon superglue needs a primer.
