We decided to lay a parquet or laminate on the floor, or maybe ceramic tiles, it can be done if the floors are perfectly even. If not, then you have to make a screed of the floor and level them. You can entrust this business to a professional, calmly prepare the necessary amount of money and enjoy the result, and you can devote a little of your precious time, and make a screed yourself.
How to prepare a screed solution
How, you probably already understood, the screed must be done if the floor is not even, and so that the floors can withstand a certain load.
Types of screed:
There can be several types of screed:
The main thing is concrete and cement-sand;
dry (gypsum);
magnesite;
anhydrid;
mosaic;
epoxy;
asphalt;
bulk floors (composition: cement, sand, plasticizers, aggregates)
If the screed is made right on the floor, then it is called stiff or baseless. A screed arranged on a layer of waterproofing, heat or sound insulation, it is called separate or “floating”.
The stage of preparing the floor for screed is to cleanse the surface of the overlapping of excess waste and dust. In addition, the floors need a primer, and possible cracks in lighting with a thick solution. Even all walls and partitions must be fenced from moisture absorption. How to provide it? Glue the strip of roofing material on the very bottom of the walls so that, its upper edge protrudes approximately 15 centimeters above the level of the future screed.
How to prepare a screed solution
The quality of the floor will depend on how the screed is laid. In the process, all important characteristics of the technology used should be observed. Close attention is paid to the process of manufacturing the working solution.
Preparation of a screed solution
This is what is needed for the preparation of a screed solution:
Cement
Construction sand
Polypropylene fiber
Plasticizer
Water.
You ask what ratio there should be components? It all depends on the purpose of the floor.
If the room has too intense cross -country ability, then cement and sand should be in a ratio of 1×3 (that is, 1 part of cement and 3 sand). Thus, the screed will turn out to be particularly strong. First of all, this applies to public buildings, where day after day it provides for the passage of a large number of people.
Resident
Naturally, the load in a residential apartment is much smaller, so it will be appropriate to use a screed with this ratio of cement of sand: 1: 4. As a result, you should get a strong quality screed solution. And here exactly the case, with an increase in the fraction of the sand, is associated with the destruction of the floor screed.
It is necessary to make a solution using fiber fiber. Ultimately, its share should occupy approximately 900 grams per cubic meter of the mixture. But about the required amount of plasticizer, the packaging itself will indicate you. Most often it depends on manufacturers.
Do not forget about another important component in the solution – this is water. It is added based on: 50 kilograms of cement and 15 liters of water.
If possible, mechanize the construction process by modern means. There are even devices that themselves will dose the necessary components. You only need input using the control panel of the necessary proportions of the solution. If you are not rich in such equipment, then measure proportions with volume from the calculation of the entire weight to volume. In this case, buckets, shovels and similar inventory will help you.
How to prepare a screed solution
Remember, after the floor screed, before laying parquet or laminate, you should go through at least 30 days. It is during this time that the cement floor will completely dry and become durable.
