It’s annoying to pay for expensive construction services that you can do yourself. We offer a master class on making floor screeds using Strong coarse leveler. This material has advantages over cement-sand mortar, which was used before the advent of more modern, practical and economical compositions.
By following the technology, you can make a high-quality screed using a coarse leveler without the involvement of hired workers. To do this, they sequentially act according to the stages of work described in this article.
Preparatory work
The floor in the room is cleaned of dirt and dust. Professionals use powerful vacuum cleaners for this. At home, you can get by with a broom. When the cleaning work is completed, you need to treat the floor with a primer. It is recommended to use “Concrete Contact”, as this product perfectly increases the adhesion of the base and creates a waterproofing layer. As a result, the chances of wetting the ceiling of neighbors living below are negligible.
The primer should be applied in a continuous layer so that no untreated areas remain. To do this, use a wide brush or roller. The composition is poured onto the surface to be treated and distributed using a tool. This operation is best performed with gloves and work shoes to avoid getting dirty.
After priming the floor, you need to wait some time for the composition to dry completely. It is not recommended to carry out work on an undried base, as this will lead to reduced adhesion.
Installation of beacons
The fundamental factor for creating an even screed using a coarse leveler is the use of special profiles designed to create a single plane. Beacons have a hole through which they can be attached to the surface. In our case, the installation is carried out using a leveler. This will provide good rigidity.
The profiles are distributed in the room in increments equal to the length of the rule. This will provide the opportunity to distribute the leveling mixture over the beacons. At the next stage, holes are drilled in increments of 50 cm along each profile.
For perforation, a drill with a diameter of 6 mm is used. Plastic dowels are inserted into the holes and screws are screwed in, which will serve as stops for the beacons and will create a single plane.
To align the screws, use a laser level and a screwdriver. The device is installed indoors and turned on.
It is necessary to screw 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 the hardware using a screwdriver. At the same time, use a tape measure to control the length of the gap between the head of the fastener and the level beam.
When the screw heads are located at the same level with each other, mix a coarse floor leveler and apply it along the hardware. The profile is placed in the solution and rests against stops made of fasteners. Use a spatula to level the solution so that it does not protrude above the profile.
Such operations must be done with each beacon. After the composition has dried, you can begin leveling the floor.
Filling the screed
The mixture is mixed with water in a container and thoroughly mixed with a drill with a mixing attachment. When preparing the solution, you must follow the manufacturer's instructions regarding the ratio of water and dry composition.
The finished solution is poured into the spaces between the beacons and leveled using the rule.
If voids form on the surface of the screed during work, they must be filled with mortar and leveled again using the rule. After performing such actions over the entire area of the room, the work on the screed can be considered complete. The coarse leveler is not susceptible to cracking from exposure to sunlight, so the screed does not require maintenance during drying.
