Are you using the actual Harmonics stairnose?  Did you purchase it from them or are you using a different one?  Reason I ask is that we haven't started yet.  I told hubby I wanted all baseboards back on the office we just completed before starting the stairs (((scary music playing))).  We are probably going to go to Home Depot and buy the Corner Round to put on the stairs and then stain it.  We have a double staircase, so it is even more expensive.  I am nervous, but we still need to buy a jig-saw to cut off the lip on the stairs now.  I will ask him what he thinks about your post.

i am using the stairnose ordered from harmonics themselves.

Im against filling the gap with any kind of silicone for a reason or two, and I do have a solution if nothing else presents itself, but when I called them (two separate times without giving my name, and they said BOTH TIMEs that they had never heard of the problem before) they also said just to fill it with their color match filler.


please please please, If you could just take a look at how the install would go if you were doing it, to see if you run into the same thing  (just line up a piece of laminate and a piece of stairnose with the nosing overhanging the edge of some flat surface and tell me if there is a gap....because if there isn't, something is very wrong here.



If nothing else, Im just going to get some thin wood (door skin or whatever I find in the thickness I need) and shim up the laminate piece and leave the stair nose flat on the step.


I __DO__ plan to run a very small bead of clear silicone caulking on the edge of the lip to seal out dirt and to prevent the stairnosing from delaminating after usage.
