Hi,

I'm attempting to fix our shower cubicle which had the tiles snapped into two because the the water was seeping though and expending the plasterwork behind.

So far I've removed the tiles and damaged plasterwork with a chisel and hump hammer to expose the brickwork behind. I have found that the some of the bricks are ever so slightly loose as I noticed movement whilst pulling away the plaster, and that the mortar is incredably dry and crumbly/powderly with a texture not dissimilar to clay.
The property is a standard London terrace and dates around the 1900s.

The question is, should I be "repointing" the brick work as there are quite deep holes in the mortar and to add a bit more structural strenght before I add the base plaster? I was also wondering if the mortar is lime mortar and should I be using this for the repairs?

Cheer, Ian
