I have a concrete staircase with banana-shaped steps. I'm not sure if it was intentional or if they built too weak a mold, but the steps are 120 cm wide and about 1.5-2 cm bowed outwards in the middle.
I thought about trying to lay tiles, 30x60 cm, and straighten out the steps so I need to lay then 15-20mm at most of adhesive towards the edges.
I found this one that can build up high, Keraflex Maxi S1, but it's quite expensive and hard to find (without paying insane shipping) so is there another adhesive that works with such thick/high layers?
