Can I Use Gripfill to Replace Two Bricks on my Small Garden Wall?

[Maggie1]

Two bricks have come off on my small garden wall. I was wondering if I can use Gripfill to put them back in place.
I can't use plasterboard or anything as a trellis fence goes on top so it has to be the same height as before.
Thank you in advance for any advice.

Should be ok, I've used no more nails to put a coping stone back on, lasted a good few years.

I would go for a MS polymer such as Sticks Like Sh*t.

It will stick to the existing mortar even if it slightly damp.

Ensure that the mortar is not dusty.

The "glue" line will be less than 1mm thick.

Use soudal fixall.
I used it on a few bricks of a wall that had to be demolished 18 months later.
When we took it down those bricks would not come apart.
A lot stronger than mortar.

Done this several times. Just make sure you get exterior grade
