The most optimal option for replacing old,creaky, rotten, uneven floors will be a concrete screed. Such surfaces differ in strength, strength, in addition, they will be dry due to the waterproofing substrate. The concrete floor is an ideal base for laying tile, parquet, laminate, as well as materials based on natural stones (marble, granite, etc.). The concrete floor screed is ideal for installing a roughing of wood chipboard for the further installation of any flooring.
Before you start laying carefullyplan all the work. The concrete screed should not have a thickness of less than five centimeters in the base, therefore, in advance it is necessary to measure the height of the door openings. All the communications passing under the future floor need to be closed with casing and carefully insulated. Also important for laying the floor is the fact that there should be no overlapping of the ventilation of the wooden floors located in the neighboring rooms. To prevent this, you should lay 100 mm diameter plastic pipes on the floor. They should go from the holes of the outer walls to the ventilation units of the internal floors.
Starting work, you need to check the availability of allnecessary materials. For concrete screed all you need (except sand), you can buy in any construction shop. Sand is ordered in organizations engaged in career development. Sometimes you can buy a ready-made solution.
To ensure that the concrete floor screed is of high quality,you need to calculate the required amount of material. To do this, the floor area is multiplied by the thickness of the future screed. The material should be purchased based on the proportion of cement: sand: crushed stone (gravel) - 1: 2: 3. Sometimes it can be considered and in another way: six parts of the finished mixture of sand and gravel take one part of the cement. It must be remembered that cement should be stored in dry rooms.
If the room where the screed will fitconcrete, has a large area, and it is necessary to produce a mixture of a large volume of solution, it makes sense to worry about an electric concrete mixer that can be hired.
To prepare the solution, in a concrete mixer for twoone third fill dry materials in the above proportions. The components are then thoroughly mixed, adding water to obtain a uniform consistency. The following mixtures can be carried out, immediately pouring water, and after adding the mixture.
All work should be done in mittens or gloves, which will protect your hands from the corrosive effect of cement mortar. Having finished the work, the tools and the concrete mixer must be thoroughly washed.
Before the concrete screed lays on the floor,The room is divided into strips about a meter wide. Begin the installation from the far corner of the room, moving towards the doorway. After installation, the concrete should be kept wet for two weeks, then you can mount the parquet, tile or perform other work.
If the concrete screed is laid on the street, thenthe technology is somewhat different. On a clean ground pour several layers of different materials. First lay gravel or gravel, the thickness of the layer should be about twelve centimeters, the second layer should consist of sand. Further, the surface is leveled and the protection from the waterproofing material is spread. The edges of the waterproofing must reach the walls above the level of the concrete floor. The next layer is laid with concrete, and in the end the screed is poured with a liquid cement mortar.
If everything is done according to the rules, then the concrete screed does not require further maintenance. And when it breaks down over time it can always be replaced.
