Something I get asked to do quite a lot is repair brick pillars - sort of thing you find at the end of a low garden wall.
Usually a 'lump' of brickwork is loose e.g. 3 or 4 bricks which are themselves firmly held together by the mortar.
Rebuilding means separating the bricks, chipping off the old mortar (not always easy) & re mortaring in the usual way. Time consuming.
Are there any adhesives capable of just gluing back said lump? Epoxy or one of the latest grab adhesives?
Obviously have to be pretty strong.
