This is a double-wide mobile home. We just had it professionally releveled last Saturday. It has an OSB subfloor. We are planning to install vinyl plank flooring. In the picture, we are flooring the Master Bedroom and closet, Office area, Living Room, Kitchen/Dining Room, including under the fridge and inside the two pantries, Guest Bedroom and closet. Each square represents 1 square foot. We are leaving the linoleum in the Master Bathroom and Laundry/Hallway/Guest Bathroom. The arrows represent doors.
The tiny bit of the subfloor that I have seen so far is not great, but I don’t want to add hundreds of pounds of concrete to the weight of the home in order to level the floor. I am think that I can chip out the high spots and smooth it out with whatever product you recommend.
