We expect cement consumption to the screed to avoid unnecessary costs

all exactly as in a drugstore

calculation cement screed produced in kilograms per cubic meter of solution (you can also count per cubic meter of sand).The exact amount, largely depends on the grade of material.Screed in apartments and houses is most often done with the use of marks M150 and M200.To determine the exact amount needed to settle ties.For example, we perform the calculations required amount of materials for screeds:

• Making pouring a thickness of 5 centimeters and 40 square meters.
• believe: 40 m2 x 0.05 = 2.0 cubic meter of mixture.Sand and cement are in a ratio of about one to three.It turns out that you need to at least 1.5 cubic meter of sand and 0.5 cubic meters of cement.

However, consider the fact that the mixture during cooking loses its volume.This is due to the fact that small parts filler fill the void in the mixture.Therefore, from 1 cubic meter of dry mixture obtained about 0.7 cubic meters of concrete mass.Consider the difference in the loss of volume and use more of the dry mixture.

Note!The sand for making screed solution should be fine grain.

What and where to use?

Before starting the preparation of the solution should be to decide what is best for cement screed.Many manufacturers write on the packaging, the purposes for which this brand is more suitable products, but the general recommendation is still there.Firstly, you need to take into account the cross-country.Thus, the tie for the apartment and the hospital corridors will be quite different, as in the flat floor is not subjected to such high loads, both in the hospital.Second, the material is considered to be applied onto concrete.For example, if the final coating acts as granite, the cement must be of superior quality.

Note!Choosing the material grade screed, we recommend to consult with a specialist.

for leveling floors in houses and apartments the best option is to use the M200 brand.Mixing occurs in a proportion of one to four, that is part cement and four parts sand.A tie layer is 3 cm thick.Drying it for 2-3 days.In public places, better use of M300 cement.It is mixed in the same proportions as the M200, but drying for 4 days.

Each brand of cement screed, in addition to cement, sand, rock dust needs.Standard mixing proportions - 1: 4: 4 (a portion of cement accounts for four parts of sand and rock dust).The layer thickness of such a solution should be not less than four centimeters.It dries the mixture for three or four days.It is ideal if the floor will be faced with granite.

casting process floor

If you understand with what is needed and how much solution should be cement screed, comes the turn of her casting.Independently make it difficult, you need only adhere to the work technology:

• Paul cleared of debris, and marked the highest points screed;
• Mounted lighthouses, lighthouse rail can act in their quality;
• To the solution froze quickly, it is added to the gypsum;
• After installing beacons begins installation of the intermediate elements;

ImportantTo make the correct installation of the intermediate elements, using monofilament thread that stretches between the base profiles.

• kneading solution;
• on pre-wetted surface is filled with the mixture.Pour recommended in the space bounded by the two lighthouses;
• After pouring the floor hiding film 12 hours for aging;
• Thereafter, the entire surface is overwritten wooden float;
• dismantles band beacons and overwritten by them.
