Here’s the thought. I fabricate solid surface countertops I have a lot of leftover Dekton 1/4” thick material. I would like to do my interior stairs, tread and riser as one piece joined on a 45.
So far I have preped the structure of the stair case to stop deflection and sheathed the tread with 2 layers (3/4” each) screwed on 4” 7 ply plywood. And caped the riser with 12 ply 3/4 plywood. What adhesion should I use and how thick will it be after setting so I can account that in to my measurements. Should I leave small gap filled with color matched silicone for expansion on each step or just top and bottom of the stairs? I’ve never seen or done this type of application and seek the advice of flooring experts thanks.
