Repairing garden wall that s falling apart?

[pointedstarman]

I have to repair / repoint a garden wall that’s old and the outer layer is falling apart. I don’t want to knock it down and am fixing most of it by repointing and replacing bricks where needed. There is a section behind a shed that I can’t practically get to and was wondering if there’s some kind of spray that will seal the existing bricks and mortar? Any suggestions would be greatly appreciated!

There are a fair few products. Unibond was a traditional solution to stabilising bricks but I'm sure there are modern alternatives.

Thompsons weather seal does this (it won’t stabilisce the bricks mind)
