Two rooms in my house are connected with a set of concrete steps (one tread). As built, the ledge for the first step is inline with the wall framing.
This means that when I add drywall the finished door frame will extend 5/8" over the ledge. I would like to double-rock this wall so now I'm looking at 1-1/4" overhang.The finish floor will likely be tile or perhaps something like a rubber gym mat.
I would like to add material to extend the top step by 1-1/4" but I don't want to break and repour the steps.
I'm thinking of getting a solid plastic board (like decking maybe?) And trimming it down to fit. Then glue + tapcon into the slab to hold it.
I have measured and the resulting tread depth will be 11-1/4" (currently 12-1/2")
How might I accomplish this?
