Son's cabling initiative continues to throw up questions.

He has got the hall back to bare brick and blockwork, with the intention
of getting all the CAT6 cables into place and then employing a good
plasterer to finish the walls over the top. My suggestions of plastic
ducting have been rebuffed.

The cables have to go round a few corners and along lengths of wall, so
we need to tack them in place for the time between the cabling and the
plastering. It's moderately dusty.

My only thought is to use hot melt glue gun to tack the cables on, but
is there anything better? It has to be very quick drying
