Taping the concrete wall of an apartment easily and quietly (Magnetic Door Stopper Installation)

When you work on the concrete wall of an apartment,
It's best not to damage the neighbor's house, but to pierce it quietly.
It's the technology and manners of the day.😉
I've been installing a magnetic door stopper in my house.
I'm going to show you some know-how in drilling concrete walls.^^
