So I have a slight issue. Gut my bathroom, replaced door boards with plywood, but also brought the floor to level. There are some gap areas since I could only take out so much of the floor. Anywho, the flooring that runs along the door has a gap about 2 inches wide and going from 1/2 inch to about 1.5 inches. Can I use leveling compound for this area? Make a shaped wedge?
