Does anyone know why hollow core doors have a striped/ridged edge? And can it be removed? Hume brand hollow core doors from Bunnings were used in my home renovation. After painting, every door has a partial ridged/striped finish, on the edge, where the hinges are attached. I've been told this is how they're manufactured there is nothing you can do, or a power planer has "chattered" on the door edge leaving stripes, or the painter should have sanded to remove the stripes/ridges, or the carpenter should have filled to a smooth finish. QBCC said it was manufacturing and rejected it. I can't believe that, as Hume sell millions of these doors and nobody would use them if this was the finish. The old hollow core internal doors were smooth, for comparison. Would anyone know what this is, how to fix it, and who is responsible for the fix (carpenter or painter) please? Thank you.
