Polyurethane flooring primer
The first step is to clean the polyurethane flooring, which is done in different ways according to its dirty condition, after which the floor should be sanded for more cleanness and creating suitable scratches. After completing these two steps, the primer coating should be applied on the floor. In this step, the diluted polyurethane liquid with high permeability should be poured on the floor. Creating a surface with high adhesion will protect the next layer from the separation of the floor in the future.
Therefore, the life and durability of the flooring directly depends on the quality of the primer, and choosing the right type of primer and the dryness and cleanliness of the surface when doing it is very important. One of the most important issues that should be considered before applying the primer is the complete dryness of the surface and not paying attention to it will cause a lot of damage.

Barite powder
Barite is the most common barium mineral in nature and is an important additive in many industries, especially in the paint industry as a filler. This mineral has a specific gravity of more than 4 and its powder color is from white to gray.
Barite is widely used in the oil and gas drilling industry due to its neutrality, reasonable price, high specific gravity. The great advantage of barite in the paint industry is that it has no pigment effect and is used for uniform distribution of colored particles. And usually comes in 20 kg bags.

Polyurethane resin
Polyurethanes are polymers that have a urethane bond. This bond is formed by incremental adsorption between an isocyanate group and an active hydrogen compound. Isocyanate groups are highly reactive and therefore do not require an increase in temperature to advance their reaction. Polyurethane resistance to abrasion, impact and cracking is very good and hardens at ambient temperature and its resistance to sunlight is much higher than the epoxy group.
Calcium carbonate powder
Calcium carbonate is a widely used substance in the earth's crust. Calcium carbonate is a type of sedimentary rock that has formed over millions of years. Calcium carbonate is found in mines in the form of calcite, aragonite, marble, limestone.
This material has a high melting point of about 1339 degrees Celsius and is non-flammable and non-toxic.
This mineral is widely used cheaply and is a suitable filler in many applications in the paint industry
Epoxy floor primer
:Epoxy primer
The first step is to clean the floor with epoxy flooring, which is done in different ways according to its dirty condition, after which the floor should be sanded for as much cleaning as possible and to create suitable scratches and scratches. After completing these two steps, primer coating should be done on the floor. In this stage, dilute epoxy liquid with high permeability should be poured on the floor with good adhesion after drying to be able to insulate the surface in terms of moisture passage with the necessary strength and create High adhesion surface to protect the next layer from the separation of the floor in the future. Therefore, the life and durability of the floor directly depends on the quality of the primer and choosing the right type of primer and dryness and cleanliness of the surface when doing it is very important. Epoxy floor primers They are mainly divided into the following two groups:
Epoxy Polyamide Flooring Primer: EPD-01
This primer is produced and presented based on bisphenol () and hardener polyamide () resin. In the production of this product, a special composite solvent is used, which reduces the viscosity of the product to increase its penetration into concrete and substrate. This product has a very good adhesion to the floor and the subsequent layers adhere well to it, and also due to its good flexibility, it does not crack or break.
EPN-06 Epoxy Polyamine Flooring Primer
This type of primer is produced and presented on the basis of bisphenol () and polyamine () hardener resin and its viscosity is reduced by a special solvent and penetrates the concrete surface and hardens after hardening of the concrete surface. This product is mostly sensitive to floor moisture. It is used in very dry places and special places and its surface becomes hard and brittle due to being more expensive and also the above mentioned cases. In most places, polyamide primer is used for epoxy flooring.
