before a screed floor, you should decide what is needed operational strength of ties.For residential premises is sufficient if the strength of the concrete will be equivalent to the M-150, and therefore, it is possible to use simple cement-sand mixture to a commercial or industrial premises already required polymer-equated strength to concrete M-400.

first need to be found at the highest point of the floor.If the vertical drop - 1-1.5 cm, it is recommended to use self-leveling leveling-mass if more - the cement-sand mixture.

should be put on the floor a special primer mixture to increase adhesion to concrete ties.The degree of dilution as a primer depends on the uneven floor.It is believed that if a vertical drop of up to 2.5 cm - it is necessary to dilute it to a "jelly", more than 2.5 cm - to "sour" state.

After finding the highest point of the floor, you want to install beacons.At the same time it should be noted that the screed height must be at least 3 cm above this point.Mounted alabaster beacons, or they can be installed in specially drilled holes in the floor.Now the breed mix and put on the floor.When using the filling mixture to be applied to the floor, it must be leveled and the amount of 2-meter rule, periodically checking the leveling.If it takes half-dry mixture, at first we put a base layer laid on him a metal grid and causes a second layer of the mixture, which is already aligned and a wide spatula.If necessary, the mixture can be refilled.

When coupler can withstand the weight of the body, remove all beacons and cover with foil or a damp cloth for 10 days.This creates optimal conditions for drying and the acquisition of the strength properties.Completely dry screed four weeks.
