A screed with a rough grinder is the best way to level the floor in an apartment
It's a shame to pay for the expensive services of builders that you can do yourself. We offer a master class for the manufacture of floor screed using coarse leveling agent Strong. This material has advantages over the cement-sand mortar, which was used before the advent of more modern, practical and economical compositions.
Observing the technology, you can make a high-quality screed using coarse rovnitel without attracting hired workers. To do this, consistently operate according to the steps of the work that are described in this article.
The floor in the room is cleaned of dirt and dust.Professionals use powerful vacuum cleaners. At home, you can do with a broom. When the cleaning work is completed, it is necessary to treat the floor with a primer. It is recommended to use "Concrete Contact", as this tool perfectly enhances the adhesion of the base and creates a waterproofing layer. As a result, the chances of watering the ceiling of neighbors living from below are negligible.
The primer should be applied continuously so that there were unprocessed plots. To do this, use a wide brush or roller. The composition is poured onto the surface to be treated and spread out using a tool. This operation is best done in gloves and work shoes, so as not to get dirty.
After the floor is primed, time for which the composition will dry completely. It is not recommended to carry out work on not dried basis, as this will lead to a decrease in adhesion.
The fundamental factor for creating a smooth tie with a coarse rover is the use of special profiles designed to create a single plane. Lighthouses have a hole through which they can be mounted to the surface. In our case, the installation is performed using a rovier. This will provide good stiffness.
Profiles are distributed indoors with a step equal to the length of the rule. This will make it possible to distribute the leveling mixture over the beacons. The next step is to drill holes in 50 cm steps along each profile.
For punching they use a 6-diameter drill mm. Plastic dowels are inserted into the holes and screws are screwed in to serve as stops for the lighthouses and create a single plane.
To align the screws, use a laser level and a screwdriver. The device is installed indoors and included.
It is necessary to twist the screws into the dowels so that the distance from each of them to the laser beam is the same. To do this, screw-in hardware. At the same time, the length of the gap between the cap of the fastener and the level beam is controlled by a tape measure.
When the screw heads are placed on the same level with each other, they will mix a coarse leveling device for the floor and apply it along the hardware.The profile is placed in the solution and rests on the lugs of fasteners. The spatula is used to level the mortar so that it does not protrude above the profile.
Such operations must be done with each beacon. After the composition has dried, you can proceed to leveling the floor.
Filling the screed
The mixture is closed with water in a container and mixed thoroughly with a drill with a mixer nozzle. When preparing the solution, it is necessary to follow the instructions from the manufacturer regarding the ratio of water and dry composition. The ready solution is poured into the spaces between the beacons and leveled using the rule.
If, during the work, voids are formed on the surface of the screed, they must be filled with mortar and re-aligned with the rule. After performing such actions on the entire area of the room, work on the screed can be considered completed.The coarse leveling agent is not subject to cracking from the ingress of sunlight, so the screed does not require maintenance during drying.
