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.

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.

Polyurethane hardener
The most important hardener used in polyurethanes is hardener
Desmodur N75
After the reaction of hardener and resin, which is an exothermic reaction and does not require heat to continue, and the result of this reaction is a stable material that is used in many industries such as flooring and protective coatings for pipes and metal structures and many others.
Epoxy resin
Resins used in the flooring industry are mainly divided into the following two main groups
Resins used in floor primers that are used with polyamide hardeners
Resins used in veneers and floor coverings, which are mainly used with polyamine hardeners, and the most popular is 828 resin.
Hexion Company, which is very famous due to its low viscosity and excellent adhesion, and chemical resistance.
It is very good and in dry weather it has little sensitivity to temperature changes and its mechanical properties do not change over time.
Resins that can be provided in translucent floors with 828 resin or its quality equivalent.
Epoxy floor thinner
Active or reactive epoxy thinners
These diluents participate in the reaction and form part of the non-volatile binder. These diluents are non-volatile and do not evaporate. These low-viscosity liquids, when mixed with the original resin, reduce the final viscosity. In addition, the diluents improve the resin flexibility and the air bubbles formed leave the reaction faster.
Inactive epoxy thinners
These diluents do not react and are volatile and usually have high evaporation. These solvents reduce viscosity and cause problems such as reduced final strength after drying, risk of fire, evaporation and risk of poisoning by it.
