Kitchen how to fix wooden worktop upstand to wall

[TofuSpaceship]

Hi all

We have bamboo worktop and bamboo upstands to match.

How would you fix this to the plastered and painted wall?
Would you use the same silicon sealant that will be used to seal the corner between worktop / upstand and upstand/wall?

Would you use pink grip?

What else and why?

Thanks!
