I am doing a small home improvement project by removing the door between the entrance room and the corridor in the apartment. I've managed to remove the door and the bricks around it and am now left with a "scar" across the wall and ceiling.
I would appreciate advice on what material to use in order to achieve if possible:
A solid result that can be second coated with wall mud, sanded and started to be painted over after 3-4 days
I've researched that overall "best material" to use is cement compounds, however, on most of the begs it says 28 days drying before painting. Please let me know if I am unrealistic in my expectation and advice on the best way to address this problem, I would prefer the harsh truth now rather than cracks in the wall or pealing of paint a few months later :-)
