What Are Self-Leveling Polymer Floors?
Self-leveling polymer floors are leveling compounds made of polymer materials. These materials can be used on concrete substrates as a topcoat. They can be based on polyurethane or epoxy resins.
They have high adhesion to the base, flexible and durable surfaces. Due to these qualities, these materials are widely used in various industries with vibrating equipment, also in sectors where floor coverings are exposed to high loads. The video shows the technology of their manufacture.
Self-leveling epoxy floors – harden faster and have a higher density than polyurethane. Because the thickness of this coating is more increased, it has lower adhesion to the substrate and high resistance to mechanical stress. They are widely used in public buildings and industrial premises. All stages of production are shown in the video.
Polymer Floors: With a Polyurethane Layer, Epoxy-Based, Unlike a Self-Leveling Foundation, Self-Assembly
To create a quality surface, you can use polyurethane or epoxy flooring materials. Such materials are becoming more and more popular. Polyurethane materials have slightly different properties than epoxy materials.
- Polymer floors are characterized by high abrasion and shock resistance.
- These coatings do not deteriorate under the influence of chemically aggressive substances.
- They are resistant to heat and ultraviolet radiation.
- Positive hygiene indicators.
- Easy to clean and repair.
- Good decorative qualities.
Polymer Floors Using Polyurethanes
Several methods of pouring such floors allow you to endow the base with the necessary performance characteristics. The choice of the procedure depends on the thickness of the sprayed layer and the purpose. Using the method of application of the material, you can endow the base with strength and dust-free qualities, an aesthetic appearance, or increased resistance to wear.
- Polymer self-leveling floors, filled with quartz-filling methods, can withstand heavy loads and last 10 years. They have abrasion resistance and an aesthetic appearance. They consist of two layers: a primer and a two-component and two-component material with a filler of quartz sand.
- Thin-layer polymer floors – have a thickness of 0.3 to 1 mm. They consist of a primer layer and a one-component finishing layer. They create a dust-free effect and serve to protect concrete from destruction. They are used in utility rooms, as they do not have an aesthetic appearance.
- Bulk pouring method – polyurethane floor, poured with a thickness of one millimeter and more. It is used on-site to create an aesthetic coating that will serve to protect concrete. Resistant to abrasion and resistant to mechanical stress.
Epoxy-Based Self-Leveling Floor
Due to its positive quality, this material can be found in many public organizations. Among the disadvantages of such a coating, it can be noted that it is applied immediately to the entire area of the room. And also the fact that after the components have hardened, there is no way to make repairs.
When creating the flooring, epoxy resin is mixed with a hardener. Such a composition can be poured onto almost any base, but it is recommended to pour on a prepared screed. But before running on a fresh screed, it is necessary to pause for a month. Since the moisture content of the base should not exceed 4%, it is required to wait until the screen is completely dry. You can also cover it with a waterproofing primer. The technology for carrying out such work can be seen in the video.
When working on an old screed, this surface must be carefully prepared. Completely eliminate old cladding and irregularities. To level the old screed, you can use self-leveling mixtures, which also belong to the category of bulk.
The Difference Between a Self-Leveling Mixture And A Polymer Floor
In an apartment or a private house, thin-layer self-leveling mixtures with 3-5 mm thickness are used. In industrial premises, industrial self-leveling floors are poured with a thicker layer. The self-leveling combination is a free-flowing composition mixed with water. The polymer composition consists of components based on epoxy resin or polyurethane, and water is not used in such mixtures. The properties of such mixtures make it possible to manufacture industrial self-leveling floors in large areas. Epoxy or polyurethane materials are used on concrete substrates, and a wooden base can also be leveled with a self-leveling mixture.
How Do You Pour Self Leveling Cement?
To install such a coating, it is required to prepare the base in the same way as before pouring epoxy floors or polymer self-leveling floors. The surface of the concrete or screed is thoroughly cleaned, and all defects and defects are removed. Before spraying, the surface of the concrete or screed must be primed. This will provide a quality grip. Use a roller or brush to apply the primer.
Using a laser level, you need to measure the perimeter of the room and apply marks on the walls, determining the thickness of the layer and the border to which you want to fill.
The mixture is closed in a container, and the components are thoroughly mixed using a perforator with a whisk. The proportions indicated on the bag with the self-leveling mixture must be observed when loading the ingredients into the container. Stirring is carried out until complete elimination of lumps and obtaining a homogeneous mass.
The mixture is poured from a container onto a concrete base and leveled with a notched trowel. Then, for even distribution, they are rolled with a toothed roller. The level of the mixture should reach the marks that are on the wall. After the composition has hardened, fragments of the damper tape are cut off.
Polymer Self-Leveling Flooring Technology
Before pouring polyurethane or epoxy floors, it is necessary to carefully prepare the surface. The quality and durability depend on this. Before starting pouring, it is required to completely clean the surface from dirt and dust. Despite the excellent adhesion provided by the primer, it will not be superfluous to sand the surface with a sandblasting machine, which will create a roughness. If there are damper joints on the concrete surface, then special polyurethane putties are used to seal them. The cracks are covered and covered with a serpyanka. Then, cover the surface with a continuous layer of primer.
After the preparatory stages, they begin to fill polymer floors with their own hands or hire specialists. To evenly distribute the working composition, epoxy or polyurethane floors are smooth, use a squeegee.
A notched roller is used to remove air bubbles that form during pouring. The composition is rolled with this tool until bubbles are wholly eliminated. After the first layer has hardened, the finishing layer is applied according to the same principle. All stages of the production of such works can be viewed in the video.
