I have a problem installing a moulding in a 11'x11' room. On one side of the room the ceiling is 8' height. On the other side of the room the ceiling is 8.5' height.
This gives a <4 degrees slope, almost horizontal, very difficult to insert an intermediate piece in-between.
The moulding must form an angle of 45 degrees between the walls and the ceiling.
Formulas and charts do not include that kind of slope... If the ceiling were horizontal, I would use a 35.36 degree mitre and a 30.00 degree bevel. But considering the ceiling has a slope of almost 4 degrees, what should I do?
Must I seal the "/" (or the "/" ?) with joint compound OR is there a way to include the walls-ceiling angle into the formulas?
