We have an upstairs stairway where people come out of water to enter the stairs. These are made of metal pans with concrete. Water dripping from people on the stairs leaks to the ceiling below through the edges of the steps. There are a couple of landings that are too large for on piece treads and risers to cover. I am thinking of getting this product and cutting treads and risers to cover those steps. Can this be bent and installed to cover 45-degree angles to seal the steps where risers meet tread and where tread meet walls and over the edges of steps? Would it endure foot traffic over the step edges?
