When you move into a new apartment or just make repairs in an existing one, you want the floor to be in order as well. But in order to lay parquet, linoleum or laminate, you need a strictly horizontal base. And here the question arises: how to level concrete floors? This is quite possible to do on your own, so you can save money, and you do not need special skills. It will be quite enough for you to at least once see earlier how such work was performed from the outside.
If we talk about how to level concrete floors, then it is worth noting that any work begins with marking. Find the highest point of the floor. This is done using a hydraulic level, a good cord, cups or chocks of different heights. Two people first pull the cord diagonally from corner to corner, and the third only touches the level with the cord, inserting it horizontally. All mounds on the floor should be below this cord. When you have reached the goal, a beacon is placed on the floor in the center of the room, a chock of the required height is selected, and marks on the walls are placed in the corners of the room in places where the cord is located. The second diagonal must be constructed in exactly the same way.
Speaking about how to level concrete floors, it should be noted that the highest tubercles are usually in the corners of the room, as well as where the seams are located. If the difference in height is large enough, then it’s worth assessing, maybe it’s better to cut down a high hillock than to pour almost the entire room with cement.
Understanding how to properly level the concrete floor, it is necessary to draw a marking line along the marks from the cord. This line can rise to the same height depending on irregularities, but it cannot be lowered, because the central beacon has already been set at the highest point. Now you should move the cord along the lines on the walls to put additional beacons on the floor of the room. The distance between them should be 70 centimeters. It is necessary to check the correctness of their exposure several times in order to exclude the formation of new irregularities. To do this, the cord should be pulled from wall to wall in all directions. Marks on the walls should be at the same level with the height of the beacons.
We understand further how to level concrete floors. The next step is to start pouring. Before this, the floor must be covered with soil. For screed, you can use ordinary cement mortar, but it is recommended to use a special mixture. The thickness of the mortar should be selected depending on how thick the cement screed will be . Here the principle is very simple - the thicker the screed, the thicker the solution should be. Installation of concrete floors should be carried out as accurately as possible, evenly filling the space with a solution. At the same time, the screed should run exactly along the exposed beacons. The surface should be leveled with a wooden lath very carefully. When the screed is slightly set, the beacons need to be removed, and pour the solution in their place. The surface should harden well, so you do not need to walk on it ahead of time.
Now you know how to level concrete floors.
