We now have a noticeable gap between our bottom stair riser and newly installed floor which we're not sure how to fill, as it's uneven and doesn't look good. The gap in question is shown in the attached photo. The risers will be painted white.
How would you suggest we fill this gap, so that having been filled, the painted riser looks seamless and doesn't have a visible join line?
