repairing k-rend?

[exposed]

Im not sure how to go about this.

I had a drill a hole through the wall for a camera cable and decided to go inside > out so that I didnt drill straight into wires in the wall.

The problem is that it caused a lot of blowout on the external side. its about 5" round dish shaped. can this be repaired and look fairly natural? I have been told its through colour k rend, which i imagine i can buy, but no idea how i would get the same texture or even if it can be used to repair. I also need to figure out what the actual colour is as there seems to be a load of variations

cheers
