I would purchase approved silicone mastic. Clear out any debris, and apply the mastic when the concrete is very dry.

Would a good finish be hard to achieve as a basic diyer

jack of all

I think a butyl mastic, like Rito would be easier to work with.

Could you just brush in some silica sand instead?

Get a knife or screw driver and rake out the joint, then use some grey tek 7 (or similar). Don't overfill the joint, it should be quite easy to get it smooth as it will be retained within the joint.
