I too have a warped step – this one is 11 feet long, 12 inches wide, and inch thick of solid oak. It has been ripped twice and glued back together with the center piece turned the other way. Both sides have been sealed with multiple coats of polyurethane after staining. The stair is a step down from the kitchen to the family room. We are on a slab in the mid-South. The stair is supported by two by fours cut to make a box for it to rest on. The inside of the box has been sealed with what appears to be a type of concrete or mortar – rough and grey. I then covered the top of the box with black plastic and stapled it down. Then I placed a quarter inch plywood on top of the black plastic to completely cover the opening. The step was then liquid nailed to the plywood. Step was purchased and shipped to my home.
The step warped after about 4 months of being installed – this was during the winter. And this is the third one I have installed or had installed – the other two did not have the plastic or plywood covering the box. Clearly trying to learn from my mistakes and prevent moisture from coming up from the slab.
Have removed the step and turned it over to remove the glue, sand, restain and reseal. I would appreciate any comments on putting this step back down again. Oh yes – the warp is always the front of the step curling up slightly.
