In the room where linoleum will stretch, dismantle the doors and thresholds. Remove all floor skirting boards. To do this, use a screwdriver, mount and other tool convenient for you. Adjust the lower part of the door frame so that you can stick a new linoleum under it. Free all or at least half of the room, collecting all the furniture and other items in half of the room. Having laid linoleum in the free half, move these things there and cover the other part of the floor.
