Best way of hiding tv cables on concrete wall

[Mike Johnson]

The amount of cover to reinforcement in a concrete wall, or any concrete structure is calculated for the structural integrity of the building/wall, chasing out the wall compromises that calculation, DON'T DO IT, concrete cancer is a real concern of concrete structures, and electricians are not qualified to cross that professional line, the answer is a false wall in front of the existing, without shot firing or drilling, plug and screwing the battens into the concrete wall, plenty of adhesives around that will do the job.
