I have a brick gatepost and the top three rows of bricks and cap have come off. The part that's come off holds a metal gate retainer, so I suspect that possibly the gate has been slammed hard or something.
The top part appears to have come away clean, with the layer of mortar all being on the remaining part. If put back as it is, the top fits snugly on the on the rest of the post.
I was going to try and cut all the mortar from the post, add a new layer, and fit the top back on.
One problem that I can see is that the vibration of me chiselling away at the old mortar may well part another layer of bricks further down.
One thought that did occur to me was whether there was the equivalent of masonry superglue - something I could spread over the existing mortar and then rebed the top part of the post back on it.
Is there such a thing available?
