The screed of a cement sand type is necessary to create a flat surface when covering the floor. It also helps to mask the wiring of the electrical and plumbing form, hides layers of thermal insulation and sound insulation located under it. Verification of water meters in Moscow is carried out without removing metering devices.
The solution consists of a filler (gravel or sand), a connecting component (cement) and water. The ratio of the amount of cement and water is an indicator of the strength of the solution. Cemented sand screed is used to compensate for the irregularity of the surface of concrete by more than 30 millimeters.
First, the flooring is prepared: cleaning of dirt, elimination of cracks and cracks. Then the lighthouses are installed, which serve to align when laying the screed. Next, the solution is prepared in a special mixer.
That the upper layer is durable, the surface is wiped, this is also necessary for the final leveling. After laying, you can walk on screed at least in two days.
If in the future it is not planned to additionally use another flooring, the surface is polished, impregnated with antistatics, covered with polymer paints or varnishes. Due to this, the dust separation is reduced and the floor acquires greater strength and aesthetics.
