I have some cork planks that I'm putting on some stairs. I've read some conflicting things in various places.
1) Glue down or float? I've read that if planks are on stairs, they need to be glued down. However some molding mfgs have instructions for installing stair nosing on glued or "floating" treads. Glued down makes sense to me but. . .expansion
2) I saw a video where someone claimed, since the plank was glued down, you don't have to worry about expansion gaps. The mfg of this particular plank gives specs for expansion and there are no glue down instructions, nor do they indicate that glue down is an option.
So I'm all for gluing these things down on and cutting them tight to the skirt board, I'd just like to make sure I'm not screwing myself here. The other option I was thinking would be to allow for expansion by undercutting them into the skirt. Or leave a 1/8 - 1/16 gap on each end of the tread and caulk it, but I think that would look poor.
