To fill the screed of concrete, it is better to prepare a list of tools and materials:
1. Roulette;
2. Concrete mixer;
3. Sutual shovel;
4. Two levels – water and alcohol;
5. Rule;
6. Sand;
7. Cement M500 Price;
8. Gravel;
9. Construction fishing line;
10. Reinforcing mesh;
11. Lighthouses.
The very first step in the work will be marking around the entire perimeter of the area by water level, for this the highest point is determined and other points are made from it. We arrange a reinforcing mesh throughout the area. If the thickness of the concrete exceeds 12-15 cm, then the reinforcing mesh can not be placed. For better convenience, the fishing line along the room is pulled from the marks. At least we pull on three pieces: two on the sides and one in the center. Then the beacons are laid out under the fishing line, so that they almost touch the fishing line almost.
Lighthouses are usually strengthened with cement mortar and allow to dry a little. When the beacons strengthened well, you can fill in a concrete screed. For concrete screed, the cement of the brand 400 is usually used. The preparation of the screed solution itself goes, thus, a proportion is used 1: 4: four gravel shovels, four sand shovels and one cement shovel, such a screed will be very strong. The solution is kneaded in a concrete mixer and poured the floor with it. At the same time, the solution is leveled with the rule.
