I am just about to attempt to repoint along my damp proof course, as I am having some damp issues and was advised that the mortar needed repair as the dpc seems to be quite wet in one area of my wall..
Before I do this - I would be very grateful for advice. Do I need to leave the black plastic membrane visible, or can I put mortar right over the top of it. I've attached a couple of pictures of the brick work. Do the areas shown in both pics need to be repointed? Do I need to chip out the old mortar first?
I was just going to use some u-can brick and wall repair mortar I got from B&Q.
Is there anything I need to be aware of?
