What is the best product for sticking dislodged terracotta pan tiles back onto the mortar that they were bedded down into?
This is a little stone outbuilding roofed with clay pantiles. I know normally you might drill the edge tiles along the gable and put a nail into the batten to secure them. In this case because the end wall is at an odd angle there are various slivers of pantile bedded into mortar along the top of the wall and some have been loosened and dislodged by the storm. I want to get up on a ladder and glue them back where they came from. they aren't broken.
PVA? Gripfill? Silicone? Cement?
