In the previous section, we got acquainted with different types of epoxy resin Floors. In this article, we want to learn more about its industrial types:
Types of epoxy industrial flooring
Anti-acid epoxy flooring
This type of flooring is highly resistant to chemical agents. The main application of this type of epoxy is in storage tanks for chemicals and acids and chemical factories.
Sports epoxy flooring
These types of epoxies are used in gyms, and their main advantages are friction resistance, impact resistance, friction resistance, and light reflection resistance.
Anti-spark epoxy flooring or antistatic epoxy flooring
Conductive. This type of epoxy prevents sparks from passing through a static electric current. Therefore, this type of epoxy can be used in places where the spark may have irreparable damage (such as ammunition depots and explosives storage depots).
Scratch-resistant epoxy flooring
These types of epoxies can be used in cases where surface scratching is essential for use.
Epoxy parking flooring
Epoxy flooring can be used for parking lots. In addition to maintaining beauty, these floors can have high durability against car traffic.
Hospital epoxy flooring
In cases where epoxy flooring needs to be used in sanitary environments and hospitals, hospital domestic resin flooring can be used. These floors have antibacterial properties and prevent the spread and persistence of contamination in a clean environment, especially in hospitals.
Polyurethane floors have good resistance to shocks, abrasion, and chemicals. But the most crucial property of polyurethanes is their high resistance to high temperatures and direct heat. Also, the flexibility of this type of flooring makes it perform well against impacts.
As a thermodynamic resin, polyurethane floors have a longer repair time than other floors. As a result, the time wasted for re-installation or any repairs for this type of floor increases. Polyurethane floors are UV resistant. This means that it does not turn yellow when exposed to the sun, but epoxy flooring lacks this property and changes color over time due to sunlight. Polyurethane flooring is more resistant to scratches than epoxy resin flooring for homes . Because polyurethane flooring is usually softer and more elastic than epoxy flooring, this property helps to show more resistance to scratches. These floors are also more resistant to temperature changes and humidity than epoxies.
How to apply polyurethane flooring
To perform polyurethane flooring according to the inspection and check the existing conditions, to achieve an utterly standard floor, the steps of floor preparation must first be done with great sensitivity and accuracy and with the principles mentioned below.
Various factors affect the performance of polyurethane flooring, the most important of which is the preparation of floor surfaces. So that if the surface is not cleaned of various contaminants such as dust, salt, and sediment, or proper roughness is not created on them, the resin flooring will not have the desired performance. Therefore, with this in mind, the floor preparation is done as follows and following international standards such as DIN28052-2:
- A) All concrete surfaces and other floors must have sufficient roughness due to the mechanical bonding of coatings. Therefore, they must be used with a unique concrete device before applying the polyurethane primer. Concrete surfaces should be prepared.
- B) Since polyurethane flooring should be applied on stable, concrete surfaces. Therefore, removing all loose points and areas from the concrete floor with a grinder or hammer is recommended.
It should be noted that all existing executive and expansion joints and cracks created in concrete surfaces are leveled with special mastic.
- C) As mentioned, the floor must be free of any contaminants, including dust, fats, oils, greases, plasters, as well as acidic and alkaline materials to apply polyurethane flooring. In such materials, the concrete surface is degreased and degreased using mechanical or chemical methods.
- D) After mechanical or chemical methods degrease the floor and work surfaces, the surfaces are stained with Grout Epoxy if necessary. Special epoxy grout, a composite material for repairing or covering damaged surfaces, combines pure epoxy resin, erosil powder, and micro silica. Epoxy flooring with the underlying layer is formed using epoxy grout, the pores in the filled surface, smooth polymer surface, and solid mechanical bonding.
- E) After performing all the above steps, all surfaces are vacuumed, and solvent washed.
- C) The condition of the concrete applied in the floor in terms of having a minimum mechanical strength such as compressive and tensile strengths is examined to use polyurethane flooring.
- G) Existing cement plasters or any other layer that has been applied for leveling on concrete, their adhesion to the original concrete should be tested; if their adhesion is not suitable, it is necessary to destroy and remove them.
- G) The amount of moisture in the surfaces during the application of polyurethane flooring should not be more than 4.5%.
After preparing the surface, the steps of polyurethane flooring are as follows that our resin flooring company uses, which will be discussed in detail in the next Post.
