My family noticed there's a crack in the house's exterior stucco.
A contractor filled it up with a concrete paste, smudged the region (in an attempt to make the new surface even), and then painted it.
However, there's now a noticeable mark as shown in the photo.
Is there anything that can be done to make the mark not as noticeable?
Such as applying a new layer of stucco?
Thanks in advance for your input.
