I have a new staircase that's gone in, and I've happily stained and varnished it.
Now I have a problem.
It appears that on the handrail that was varnished, some of the adhesive from tape that was holding a covering cloth in place was missed.
Its a single square right in the middle, and although I've gone over it a few times (and I thought I'd cleaned it thoroughly in the first place) it's glaringly obvious, even from a distance.
What I'm wondering is, could I sand off the varnish on that section and (hopefully) lift the adhesive, then reapply the varnish without making the situation worse?
The varnish I'm using is a water based polyurethane.
