The antonyms for the term "tore off" are fix, restore and build-up. While "tore off" refers to the act of ripping, pulling or cutting something apart, fix and restore means to mend, repair or put back together. Build-up, on the other hand, implies the act of adding layers or stacking items in a deliberate order. The opposite of "tore off" can come in handy when you want to maintain the integrity of a structure or a surface, rather than destroying it. For example, instead of tearing off a wallpaper, you might decide to build up a new paint layer, fix the cracks, or restore the original surface.
