The device is used for floor screed before laying the preparation of the coating.Screed floor provides a flat surface, waterproofing, soundproofing and heat insulation base.
The cement-sand screed is used primarily for alignment of large drops in the floor, more than 4 cm for devices such floor screed will need the following construction materials: sand, cement (you can take the finished cement-sand mixture M-100) and filler (most commonly used concrete block)
First on the reinforced concrete floor must be evenly lay concrete block, which is pre-mixed with cement to mix fixed on the ground. Then you need to install beacons, by which it will be possible to fill a flat screed. Beacons can be performed as a cement and metal. The distance between beacons should be smaller than the rule about 30-40 cm and the distance between the wall and the extreme beacon must be equal to approximately 20 cm Paul will be more smooth if the rule will be as long as possible.
In the next step device ties of cement-sand mixture is placed between the beacons.The solution should be slightly in excess of surface beacons, to align the rule after the space between the beacons were fully occupied.
If the room has a small area, about ready to apply more cement-sand mixture, it will be cheaper independently prepared solution. Per square meter of floor screed for the device you can take anywhere from 0.05 to 0.1 m3 of expanded clay and from 50 to 120 kg of mixture.
Headband with self-leveling polymer blends is also known as filler floor. This coupler has a thickness of 2.5 to 4 cm self-leveling floor is seamless and when the device must be carefully observed stacking technology mix. When the device inlet floor must use different means of mechanization. Dries bulk floor compared with cement-sand screed to 2 times faster.
