Hi, I have a low height single skin brickwork wall with some natural stone copings on it. The wall is basically at single step height between my patio and my lawn. The stone copings have been previously fixed and re-fixed using sand and cement mortar MULTIPLE times over the last few years, but, as I mentioned, because the wall is at step height, these copings have been loosened as people have actually stepped on them. I am thinking of fully cleaning the underside of the copings and the top of the brickwork and then using something like Everbuild's Pinkgrip adhesive instead of mortar. Will this do the trick? Thanks.
