Skirting - what glue/sealant? And screws?

[BotusBuild]

Installing skirting boards in first room. Cut and ready to fix.

 

CT1 seems like overkill and may be difficult to remove (if that became necessary).

 

So, which glue? Or sealant? Or silicone?

And would you screw in as well, if so what screws? Something that is hidden would be requested 😁

Our joiners insisted on cheap ass silicone along with 50mm nails. None have fallen off. Im doing our basement room this weekend and will be taking the same approach.
