Distinctive features

Self-adjusting One of the contemporary flooring materials that self-levels during installation to produce a level, smooth surface is cement-based flooring. The number and size of deformations, variations in the floor, and other elements determine the layer thickness, which can be any value.

• High resistance to compression, which the surface demonstrates after a full hardening cycle, due to which the floor is not only leveled, but also significantly strengthened.
• Resistance to moisture and water without loss of performance properties.
• Ability to use any materials for finishing – self-leveling floors can be the basis for ceramic tiles, laminate, parquet, linoleum, carpet, polymer mixture (to create a decorative effect), etc..
• Low cost – given that prices for building materials today vary enormously, this parameter is relative, but still.
• The relevance of choosing this option for the "warm floors" system.
• Ease and speed of installation – even a non-professional can pour a self-leveling floor based on cement or any other component with his own hands.
• Almost perfect evenness of the surface after hardening – the result is much better in comparison with a conventional screed.

For your home, making a DIY cement self-leveling floor can be a satisfying and economical way to get a smooth, long-lasting surface. A successful outcome depends on knowing the proper composition, since different mixes are appropriate for different situations. This post will walk you through the process of choosing the best self-leveling cement, taking into account things like application ease, drying time, and final finish, so you can take on your flooring project with confidence and achieve expert results.

Application environment

Since self-leveling cement floors are installed in many different rooms, they are regarded as universal. Although it is rarely used as a decorative coating, it works wonders when it comes to getting the floor ready for finishing.

When it’s necessary to prepare the previous coating for finishing with materials that demand an absolutely flat surface, pouring a self-leveling floor becomes relevant. These could be ceramic tiles, parquet flooring, laminate, or linoleum. Since it won’t break under any circumstances and will last for a long time in the kitchen, living room, or hallway, you can lay this kind of screed anywhere.

Cement floors that self-level are appropriate for both indoor and outdoor use. For residential buildings, gypsum or various polymer-based flooring are typically selected.

While it doesn’t contain any toxins and dries more quickly, gypsum is not appropriate for the street. In rooms with high humidity, where other finishing methods may be harmed by moisture or water, it is especially beneficial to pour the floor.

A thin and long-lasting leveling layer, ranging in thickness from 3 to 10 millimeters (dependent on the type of mixture, manufacturer, and floor features), can be achieved with modern cement and polymer screeds. It is important to keep in mind that the strength of one centimeter of such a floor is equivalent to three centimeters of a traditional cement screed.

Polymer-sand self-leveling floors are typically selected for industrial spaces because, once poured and allowed to solidify, they require only painting to produce a robust, long-lasting, and superior finish. Because of the surface’s ability to withstand the highest compressive loads, industrial parking lots, ramps, garages, and warehouses frequently use it. The floor is frequently reinforced and poured with a 50-centimeter layer, which offers superior performance qualities.

Types of cement floors

The self-leveling floor’s composition varies, and the primary characteristics, specifications, and elements of the upcoming coating are contingent upon it. The primary attributes shared by all such floors are their capacity to self-level when subjected to gravitational pull and form a flawlessly level layer.

The final two varieties of self-leveling flooring are frequently utilized in industrial settings with known challenging working environments. These materials combine to create a seamless floor with a structure that can withstand extreme humidity and frequent temperature fluctuations.

Selection of compositions for finishing

The primary characteristics that set self-leveling floors apart from regular concrete are their ease of preparation, ease of pouring, and capacity to produce a flawlessly smooth layer of any thickness. With no need for complicated preparations, numerous pours, or a layer as thick as fifteen centimeters, this type of floor can be applied as a screed. The floor will undoubtedly be flawless after it has fully hardened, ready for additional processing or the application of a decorative layer.

Features of cement floors

Polymer-based materials are used in all varieties of cement self-leveling floors (common acrylic, different kinds of epoxy resins, etc.). The properties of the screed may vary based on how much of these ingredients are present in the mixture. Certain mixtures produce a surface that evens itself out, much like a traditional screed, and others actually produce a glass coating.

• Cement – volume is determined based on the necessary parameters, purpose of the material, operating conditions.
• Sand – high quality, of a certain fraction, clean.
• Polymer and mineral additives – in the volume established by production.

High levels of moisture resistance and universal suitability for both indoor and outdoor pouring characterize floors. Specific floor requirements are taken into consideration when making a selection, and this helps determine the ideal mixture composition. The two most important requirements are resistance to moisture and abrupt temperature changes.

When good concrete adhesion is required, cement self-leveling floors work best; they are more dependable than merely putting laminate or tiles on an unprepared surface.

Features of acrylic self-leveling floors

Cement, specialized filler, and polyacrylate copolymers are components of acrylic self-leveling floors. These floors were once exclusively installed in industrial settings, but they are now useful in other settings as well.

The coating is extremely robust, long-lasting, and resistant to a variety of chemicals and moisture. These mixtures are frequently poured into subways, showers, and toilets. Installation of the floor is rapid and simple, requiring little surface preparation.

• The ability to create glossy and matte surfaces with various effects.
• Resistance to high/low temperatures, their sudden changes.
• The layer does not peel off from the surface, holds firmly and reliably.
• Durability – subject to the installation technology, the floor lasts about 30 years.
• Creation of a perfectly smooth surface, good elasticity.
• Easy maintenance – the floor is simply cleaned from dust/dirt, does not require special tools and skills.
• High drying speed until the moment when you can already walk on the surface and continue finishing work.

Coating the floor with liquid glass

You can create smooth, glossy surfaces that closely resemble glass by using liquid glass. These floors are frequently found in medical facilities because they are easy to clean, do not harbor bacteria, and are unaffected by chemicals and other factors. The material can be dyed, but it is always glossy and transparent.

Objects made with various technologies, printed patterns, etc., are layered between the layers to create 3D effects.

The primary benefits of this kind of self-leveling flooring are its flawlessly level surface, resilience to chemicals, fire, vibrations, and other harsh impacts.

Surface structure

Cement-based self-leveling floors fall under the category of traditional screeds. However, their consistency and composition are different; they are more flexible, fluid, and self-leveling. The substance can be utilized in place of regular concrete mortar, among other things, despite its unique characteristics.

• Basic – designed to eliminate (level) significant differences in the surface. Can be poured in a layer up to 8 centimeters. Cannot be a finishing coating due to insufficient technical characteristics for operation.
• Solutions for medium floors – level minimal defects subject to height differences of a maximum of 3 centimeters. Often this mixture is used to cover the base, to obtain a durable and strong screed.
• Finishing – these mixtures level the surfaces very accurately, you can lay laminate and other, more demanding, decorative materials on them. Such a mixture is usually applied in a layer of 1 centimeter.

Preparation of the base

The degree of accuracy with which the surface is ready for the mixture to be applied determines the qualities and characteristics of the self-leveling floor. Several rough works should be completed prior to laying in order to help create a surface that is both beautiful and long-lasting.

• Thorough and careful cleaning of the surface from dirt, dust, various types of debris.
• Applying a line around the perimeter of the room using adhesive tape in accordance with the level of the future floor. The width of the tape should be equal to the thickness of the floor. If the tape goes beyond the boundaries – it"s okay, then the baseboard will cover everything.
• Preparation of materials and tools for mixing the solution.
• Installation of beacons – they divide the area into zones and allow large surfaces to be filled in several times. The height of the beacons should correspond to the thickness of the coating. If the floor is level, self-tapping screws can be used as beacons, which are screwed in a checkerboard pattern with a step of one meter. If there are large irregularities, it is better to use metal corners, which are fastened with gypsum or cement mortar.
• Checking the evenness of the beacons with a building level.
• Applying the primer to the cleaned floor surface with a roller, brush, carefully going over all the roughness, cracks. After half an hour, it is worth applying another layer of primer.
• Preparing the mixture according to the instructions on the package, strictly observing the proportions and technology. The easiest way to mix the mixture is with a drill or a hammer drill with a special attachment until the mass becomes homogeneous. Then let it stand for 10-15 minutes, mix again and use.

It can be satisfying and economical to create a cement self-leveling floor yourself if you want a smooth, long-lasting surface. Knowing the proper composition is essential because it impacts the floor’s longevity and performance. The best mixtures usually consist of a combination of cement, fine aggregates, and specialty additives to ensure that the mixture sets evenly and flows easily.

Take into account various aspects such as the kind of substrate, projected foot traffic, and the particular needs of your project when deciding which self-leveling compound to use. Because every product has different qualities, choosing the appropriate one can have a big impact on the result. Making educated decisions can be aided by reading product reviews and speaking with experts.

Being organized is essential when taking on a self-leveling floor project. The compound will adhere more effectively if the surface is clear of contaminants and is dry and clean. A superior finish can also be achieved by carefully following the manufacturer’s instructions. You can create a polished floor that improves the appearance and usability of your space with perseverance and attention to detail.

You can confidently take on a do-it-yourself cement self-leveling floor project if you take the time to understand the materials and the procedure. This gives you a sense of accomplishment in addition to financial savings. In addition, the outcome will be a long-lasting, even, and smooth floor.
