My kitchen was recently remodled by the previous owner. The linoleum lookes very good until you take a close look at one end of the room. The house is 75 years old and the floor has settled. Because that end of the kitchen is where i would like to put my Refrigerate i now need to fix the floor an put down new linoleum. Is their a product that i can smooth out on the subfloor without having to tear up the existing floor. It is a framed wood floor over a crawspace. Thank you in advance for any help you can give me.
