Tom C asked:

We had a kitchen remodel with new ceiling sections and a knock down texture over the ceiling. A leak in the roof got through the ceiling along the the sheetrock seams creating a ***** and ‘flat’ texture down the seam. Does anyone know how to repair this by texturing over the seam? Do I have to re-texture the whole ceiling? Can I do a new knockdown texture over the old one? Thanks!
