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?
