Hello, I have bought a new house and lifted the carpet in the living room which leads onto other rooms with laminate floors. As the living room moves away from the other rooms with laminate fitted the floor falls towards the front of the house. I want to level the floor so the new wooden floor will be level with laminate floor throughout the rest of the downstairs so my thoughts are as follows: 1) set a screed rail using some steel angle from the area of floor which is at the correct level near the existing laminate. 2) mark where the floor starts to fall from level 3) poor self levelling compound up to the screws rail and the mark where the floor returns to correct level 4) let the initial compound dry 5) out very thin layer of compound over complete floor. any thoughts?
