floors in basements and utility rooms are self-design and are usually located directly on the ground.Solid concrete floors on the ground in basements and utility rooms made of mortar or concrete in the following sequence.

The first step is to cut the vegetation layer and smooth ground.Then we go to sleep, rubble and produce it tamping the soil.Concrete mix, made from cement, sand and gravel in the ratio 1: 3: 5 is placed in a thin layer of 7-8 cm. It is also thoroughly flatten and sealing tamper.Manipulations can be called "rough" finish.

After three or four days is possible to align the floor in the "finishing" version.The drying time of the first layer are approximate, since its duration depends on weather conditions, ie,air temperature indoors and outdoors during the production work.Also of great importance is the thickness of the plaster and its consistency, iethe degree of hydration.

Thus, in hot dry weather, you can continue to work much faster.In any case guided by the actual condition of the
coating.After all, you will need to step on it and carry heavy buckets of solution without damaging the original layer.

If after some time your floors are dried up, and you can safely step on them, go to the second stage.I recommend that before you start to put beacons.To do this, check the levelness of the finished coating layer and expose beacons of metal rails on strong cement-sand mortar, to quickly grasp it.Majachnye rack mounted parallel to the long wall.

first series set at a distance of about half a meter from the wall, ie,at arm's length.Leveling solution on the entire surface of the rule, along the wall you in any case have to tinker with his trowel.Subsequent rows in classical literature is recommended to put the building at a distance of 2 m. However, from my own experience I know that the most optimal distance - 1,5m.Although in this scenario consumption Lighthouse slats a bit more, but the solution is to flatten a narrower distance much easier.By setting beacons, beware.It's a shame when installing another lighthouse, we will bring down the previous one, is not yet fully dried lighthouse series.And then you have to redo work already performed, wasting the empty time and energy.So it is very good advice at this stage of the work: when you install beacons do not hurry and often work level.

solution for preparing a second layer of cement-sand in a ratio of 1: 2.Its consistency, i.e.We determine the amount of water added to the eye.In finished form, it should resemble a very thick cream.If you make the solution too dry, it will succumb to bad leveling and teaser will appear on the rules, spoiling the whole look of your floor.To eliminate this drawback just add a little water and bring the solution to the desired consistency.If you initially add too much water, your solution will spread, stains under the beacons, making it difficult to work.If you add too much water - do not worry, and add a little sand.

About the fortress of the solution do not worry.I offered you a part of 1: 2, but there is a second version of proportion - 1: 3.Why do I stick to the first prescription?Yes, just in case you want to add sand with highly liquid solution.If you are in order to save just make a solution of 1: 3, then you will not be able to add sand remains in the process.A very weak solution creates a fragile coating from which the sand will stand out even a broom at each cleaning.

Having achieved the desired consistency, put the mortar between majachnye rails and leveling rule.Before the final smoothing can sprinkle the top with a thin layer of cement, ieto produce so-called "cement".To prevent the formation of cracks and has finished a little watered floor dried up.Do this two or three times a day for three to four consecutive days.
