Expansion Joint Sealant Recommendations

Any recommendations for a good quality sealant to finish off the expansion joints on our house please?
The walls are 100mm block, 100mm cavity, 100mm block, white render finish.
The expansion joints are 10mm thick. We have the movement ties and the foam filler. Just need a nice long lasting sealant to finish them off.
Many thanks.

The render beads should come with there own expansion built in joint 

Hopefully you haven’t had it done yet

    Thanks everyone. I can see how this is installed with the expansion bead. Makes perfect sense now.
