Leveling the floor with a screed is a mandatory procedure if the height difference exceeds 20 mm. To work, it is necessary to prepare the solution, apply it with a spatula and level it using the rule. The main stages of work are described in the step-by-step instructions with a photo, which can be found in this article.

When is alignment required?
Alignment of an already finished screed will be needed only in cases where the total difference is large enough - at least 20-30 mm. To check the difference, use a laser level:
- It is installed vertically on the floor.
- Turn on the horizontal plane.
- They take a construction tape and set it vertically, resting on the floor at a right angle, as shown in the photo.
- Mark the value of the laser level on the ruler, write it down.
- Carry out similar measurements at several points, especially in the corners, and record all data. The result is something like this.
If it turns out that the difference does not exceed 20-30 mm, it is not necessary to prepare the composition for the screed. It is better to use levelers, that is, mixtures for bulk, self-leveling floors. There are a lot of such compositions for sale - for example, Volma, Axton, Ceresit, Founds and others.
Materials and tools
Before you figure out how to level the floor after the screed, you need to prepare materials and tools:
- dry mix for leveling;
- a set of lighthouses;
- construction roulette;
- containers, water;
- rule;
- Laser level;
- needle roller;
- putty knife;
- damper tape.
Step-by-step instruction
Now it remains to understand how to level the floor screed with a thin layer. Laying is carried out in several stages:
- Knead the glue solution so that it is of medium density - the consistency of sour cream. The easiest way is to use a ready-made mixture of well-known brands, for example, Rhodonite, Rusean Concrete 5000, Prospectors S-10 and others.
- Pour it onto the floor, trying to do it as evenly as possible.
- Using a spatula, distribute the composition over the largest possible area, moving from the wall to the center.
- Level the composition using the rule.
- In a similar way, treat the remaining area and wait 2-3 hours for the composition to dry.
- Apply a layer using the same technology and let it dry for several hours.
- Leveling the floor with a thin layer allows you to achieve an almost perfect surface.
Thus, even uneven floors with large differences can be leveled with a screed. The resulting layer will be quite thin even after 2 processing cycles. The described method is universal and suitable for different types of premises - both an ordinary room and a bathroom or kitchen.
