Polyurethane and epoxy bulk floors are monolithic coatings, which consist of polymeric materials. They have many advantages. What are the advantages of polyurethane self-leveling floors? Consumer reviews indicate that such coatings have a very attractive appearance. The materials are quite practical and durable. In addition, consumers note the ease of installation of structures. During operation, according to the owners of residential premises themselves, the coatings are resistant to chemical and mechanical influences. The self-leveling polyurethane floor does not collect dust, and its care is quite simple.
Where does it apply?
Poured polyurethane floor can withstand a variety of loads. In addition, it is distinguished by a decent appearance and practicality. Due to these qualities, the following premises are most often its area of application:
- Telecommunication companies.
- Laboratories.
- Freezers.
- Offices.
- Hotels.
- Children's and medical facilities.
- Machine shops.
- Car services.
- Parking lots.
- Food buildingsindustry (where wet technical processes are noted).
- Production facilities.
- Cottages, houses and apartments.
- Other rooms where there is a high load on the floor surface.
Classification
Single-layer bulk polyurethane floor has a thickness of up to 0.4 mm. Such coatings are also called thin-layer. They can withstand medium and light loads. Active exposure will scratch the polymer coating and wear it out. Such floors stand up to the following:
- Fuels and lubricants.
- Corrosive environments.
- Light punches.
Their repair is not difficult. A single-layer bulk polyurethane floor can be used in rooms that are characterized by medium abrasion loads, minimal humidity. At the same time, high demands are placed on the decorative elements of the surface.
Two-component polyurethane self-leveling floor
Such coatings are also called highly filled. The thickness of the material is up to 2.5 mm. They can withstand heavy and medium loads. These floors are resistant to the following:
- Fuels and lubricants.
- Corrosive environments.
- Temperature and chemical influences.
- Abrasion.
- Beat.
This type is easy to repair. Such floors can be used in any premises, which are characterized by high requirements for the decorative effect of the coating and its stability. Declared termoperation - about 10 years.
Device Features
In the context of a self-leveling polyurethane floor (industrial or domestic) is a three-layer formation.
Impregnate
It is a low-viscosity homogeneous liquid that serves as an impregnation for wood, brick and concrete surfaces.
Two-component coating (polyurethane)
This is a strengthening layer. It is a homogeneous elastic coating, which is characterized by a high level of adhesion.
Anti-corrosion coating
This protective layer is designed to improve mechanical resistance.
Required conditions
Many decide to make a polyurethane self-leveling floor with their own hands. Work can only be carried out subject to the following requirements:
- The surface temperature should not differ significantly from what is currently recorded in the room. The maximum limit is 3 degrees.
- No heaters, forced air movement, drafts, etc.
- Relative air humidity – 80%. It must be maintained during the day after the filling, as well as during the work itself.
- Recommended indoor temperature - up to 25 degrees.
Preparing the base
Before laying the self-leveling polyurethane floor, the surface must be sanded, dust-free andabsolutely pure. All oil stains and loose particles must be removed. Thanks to this, the polymer composition will hold together well. The waterproofing layer must be laid on concrete.
Shot blasting
With the help of it, the base becomes rough. This provides better adhesion of the polymer mixture. Also, thanks to this treatment, loosely holding pieces are effectively eliminated. In addition, there is a reduction in concrete surface defects.
Sanding
Provides removal of irregularities in the base, even in hard-to-reach areas. However, this process clogs the pores of the concrete with dust. Thus, adhesion deteriorates significantly. Before applying the polyurethane layer, the substrate must be checked for cracks and seams. If they are found, do the following:
- Remove dirt and dust from the seams (you can use a vacuum cleaner).
- Impregnate the surface.
- Fill cracks with putty mixture (its base should be a polyurethane composition).
Priming features
It is best to use a roller or spray gun. It is necessary to add quartz sand to the primer. Thanks to him, the surface will become rough. This will provide better adhesion to resin materials.
Mix preparation
The most commonly used two-component self-leveling floor or polyurethane primer. AllThe ingredients are mixed according to the manufacturer's instructions. It is recommended to use a mixer with reverse or forward direction. It is also acceptable to mix the components manually. The polymer mixture is prepared in two stages. If a filler is to be used, it must be added during the remixing process. The amount of material should be such that you can finish working with it within an hour. After the primer is dry, you can start applying the main polyurethane layer.
Applying technology
Laying a self-leveling polyurethane floor should begin with the underlying layer. Then rolling is carried out using a spiked roller. The top coat is then applied.
Important points
There should be a time gap between layers. It is approximately twenty hours. The temperature in the room should be at least 20 degrees. It is necessary to protect the floor from sunlight and strong humidity. After a day, you can start walking on a fresh surface. It is recommended to start the operation and arrangement of furniture after 5 days. A special varnish is applied to the floor, which is made on the basis of polyurethane. This will give additional protection against mechanical impact.
Polymerstone-2
Polyurethane self-leveling floor of this brand is characterized by high mechanical strength and elasticity. Such a coating is used in rooms that are characterized by increased requirements for abrasive and chemical resistance.coatings. This also applies to high humidity conditions. It can be used where special hygiene requirements must be met.
This floor can be laid on:
- Concrete screed.
- Old coatings.
- Rigid metal structures.
It provides an impact and wear resistant finish that is chemical resistant. For 1 sq. m. it will take about 1.5 kg of material (assuming that the thickness is 1 mm).
Precautionary practices
Coating should be done in a well ventilated area. Material may come into contact with exposed skin. If this happens to the eyes, they should be rinsed immediately with water and seek medical attention. Gloves and goggles must be worn during operation.
Required Tools and Equipment
- Special spiked soles. They are necessary in order to move around the newly applied coating. Their number should correspond to workers who use spiked rollers.
- Squeegee with adjustable gap. With it, the material is evenly distributed over the surface.
- Solvent for cleaning tools.
- Aeration needle roller. It removes air bubbles.
- Spatula. It is useful in distributing material in hard-to-reach places.
- Drill with a special stirrer. It should make no more than 600 revolutions per minute. Mixer size - a littlelonger than the depth of the container that will contain the material.
