Sand and re-varnish a flawed area on the staircase

stairsvarnishing

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.

Cheers!

Of course you can do it, and you probably can even get the polyurethane to look pretty good. The trick might be how closely you can get the stain to match. If it's a very light stain or an extremely dark stain it will be more forgiving.

If it's a tone somewhere in the middle, you will need to judge your skill level, and make sure the color is spot on before re-applying the varnish.
