products for patching cracks in mortar clad internal walls

[Jason]

Hi @warren124,

Welcome to Workshop and many thanks for joining in the discussion.

It would be great if you could provide a little more information so members can assist you with specific advice. I would particularly recommend popping up a photo of your walls and how big the cracks are so members can see what you are working with and recommend the most suitable product (and techniques) for you to use.  

Thanks again,

Jason
