Polyurethane coatings are based on polyurethane resin and isocyanate hardener, which is tough, flexible, non-toxic, safe and resistant to abrasion and chemicals. Polyurethane coatings are not flammable and today they are using professionally, efficiently and effectively. Polyurethane floors are now widely used in the food and beverage industry.

Most of the polyurethane coatings do not require any extra curing and hardening time. Polyurethane coatings can be applied at a wide range of temperatures. Due to the extreme temperatures in the shrubs, food processing plants, meat, fish and dairy products, beverage production, and pharmaceutical companies. The floors of these environments are usually at risk due to inappropriate use so polyurethane floors are well resistant to these risks. Of course, all parts of the factory do not need this kind of flooring, and in most cases epoxy floors can still be used.

It is preferred to use polyurethane systems in specific environments. When extreme temperature changes occur in the cold temperature range, epoxy coatings are tense and brittle and thus their resistance to mechanical stresses is reduced. In addition, there are usually many abrasive problems. so polyurethane coatings can protect against harmful substances and mechanical stresses.

to the applicators, polyurethane coatings provide an assurance of achieving the desired result. aside from that it has several advantages such as:

excellent in appearance

good performance despite any weather

require no post curing

resistant to chemical attack

resistant to abrasion

flexibility and resilience

low maintenance cost with long-term durability

performs good on heavy duty purpose

How to apply polyurethane flooring:

 

Preparing the surface:

The most important stage is the preparation of the surface the floor must be cleaned of all dusts and residues before starting to prime. Appropriate methods are sanding or diamond-grinding. Any surfaces that have been contaminated with oils may also require chemical cleaning. After preparing the substrates by mechanical and chemical methods, the roughed surfaces can be coated by epoxy grout to remove its stains.

Priming and filling :
This layer fills the porosity at the surface and, in addition to creating a smooth polymeric surface, makes the mechanical bonding of the floorboard to the substrate so the priming will give your floor a longer life and better adhesion to the substrate. Furthermore it will seal the substrate thus eliminating the risks of bubbles and gasses. Priming also helps reduce the amount of product that will be required in the later steps.The joints are initially discharged into V-shaped and then filled with epoxy grout with a linear expansion coefficient closer to the concrete. In addition, in areas with distortion and tensile concrete levels, this difference in surface level is resolved by epoxy leveling and a small percentage of silica mineral particles.

Applying the intermediate coating :
An epoxy coating layer is applying as a leveling agent, in order to prevent moisture penetration, as well as increase the thickness and mechanical properties. This layer, in addition to the above properties, provides maximum leveling and creates the substrate for the final coating.

Membrane coating:

In order to prevent moisture penetration, as well as increase mechanical properties and achieve higher flexibility, a flexible and water proof layer that is based on polyurethane resin, is applied on the intermediate coating.

Applying the final coating (Topcoat) :

Before applying the final coat make sure that all holes and cracks have been filled, and that all dust has been collected.

The final coat is resistant to acid, environmental pollutants, salts and industrial oils,which is abundantly visible on surfaces of heavy traffic parking. This coating is washable and has a very high mechanical strength
