For example, you need to make a transition from linoleum between the summer kitchen and the main part of the house, then first of all level the floor. You can use a shovel, then tamp everything thoroughly. In view of the fact that there may be few land, then there may be a need for lifting the floor. Use the remaining bricks, small stones. In those places that, so to speak, sunk, pour out the wems again and pour water in order to be 100% confident in the smoothness of the floor. Next, you need to concrete the coating. Before filling the floor with a cement mortar, you will need to set a kind of marking in order to have an extremely even surface. You can pull the nylon threads diagonally, use the level, since if you make a mistake with the marking, the floor will not work out really even. When you make sure that everything is done correctly, you can start filling with cement mortar in level. Again, for the solution, use screening, cement, sand, water. As for the proportions, something like this: two buckets of witing, sand and a bucket of cement. No need to make the solution too thick. When the floor dries, perform a regular screed from a sand solution, it is needed to prevent all kinds of defects, and the floor eventually turned out to be smooth and smooth. There are enough two buckets of sand and 5 buckets of cement. When the floor is completely drying, you can safely lay linoleum. Initially, of course, you need to lay the insulation, and then stretch the linoleum well, which is fixed with ordinary plastic skirting boards or at your discretion.
