[Avodah] zecher lechurban

[Eli Turkel]

In todays daily halacha from ROY, he is lenient on making
a zecher lechurban in a home based on a Rambam that
the halacha applies only for pure limestone. Since today
the wallis covered with a mixture of materials one can be lenient
except for middat chassidut.
If the wall is covered by wallpaper he requires leaving the amah by amah
empty without any black paint
