Painting an industrial floor is not just about updating the color. It is about protecting the concrete from moisture, mechanical stress, detergents, and chemicals.
In this article, we will consider the features of using and applying water-based vapor-permeable epoxy paint Teknobond 620 , which is suitable for food facilities and rooms with high humidity.
What paint to choose for a concrete floor in conditions of high humidity and heavy industrial loads?
Concrete is a porous mineral material with a capillary structure that constantly accumulates and releases moisture depending on temperature, humidity, and operating conditions.
Even after full strength (after 28 days), excess moisture of more than 4% may remain in the concrete. In addition, due to the capillary structure, moisture can rise from the soil, which gradually migrates to the surface. It is this moisture that often causes swelling, peeling of coatings and the appearance of fungus.
Teknobond 620 epoxy paint is a universal vapor-permeable "breathable" coating that allows moisture to escape from the structure to the outside without accumulating under the paint layer. The material is used for painting floors, walls, ceilings and facades, providing protection against mold formation, coating peeling and premature destruction of the base.
Due to its vapor permeability, the coating maintains its integrity even on concrete substrates with residual moisture, which is especially important for industrial and commercial facilities.
If the finish coating is not vapor-permeable, this can lead to the following problems:
✔ peeling of the coating from the base
✔ swelling and blistering
✔ cracks appear in the paint layer
✔ gradual destruction of the concrete surface
✔ significant reduction in surface service life
That is why it is important to use vapor-permeable epoxy materials for concrete bases, especially in industrial and wet areas.
Teknobond 620 is a professional two-component, solvent-free, water-based epoxy paint that combines high mechanical strength with water vapor permeability. Thanks to its water base, the material does not have a strong odor, is safer for application in closed rooms and provides reliable adhesion to the concrete base even in the presence of residual moisture. This allows you to obtain a durable, load-resistant coating without the risk of premature delamination.
Why choose Teknobond 620 vapor-permeable epoxy paint?
Teknobond 620 paint for concrete industrial floors is chosen by craftsmen, owners of warehouses, workshops, restaurants and industries for its effectiveness, ease of application and quality characteristics:
✔ Odorless
✔ Vapor permeable (breathable)
✔ Waterproof
✔ Resistant to chemicals and bacteria
✔ Frost resistant
✔ Wear-resistant
Where can vapor-permeable epoxy paint be used?
Epoxy vapor-permeable coatings are used where there is high humidity and high wear resistance and easy maintenance are required:
✔ Production workshops and warehouses
✔ Parking lots and garages
✔ Restaurants, kitchens, food production facilities
✔ Medical facilities and laboratories
✔ Shopping malls and public spaces.
✔ Schools, gyms, corridors
✔ Private houses and apartments
✔ Rooms with high humidity
We have prepared a detailed video review of the vapor-permeable epoxy paint Teknobond 620 , where we show the application of the coating on the object. In the video, the floor in the restaurant was painted in light gray RAL 7001 .
Complete technology for painting concrete floors with epoxy paint
1. Preparing the concrete base
Proper surface preparation is a guarantee that the finish coating will lie flat and serve for many years in conditions of active use and high humidity.
Before applying Teknobond 620 epoxy vapor-permeable paint, you must:
To improve the adhesion (bonding) of the paint to the base, we recommend using the epoxy vapor-permeable primer Teknobond 120. This is a two-component water-based epoxy primer that:
2. Mixing of two-component water-based epoxy paint Teknobond 620
Epoxy vapor-permeable paint Teknobond 620 consists of two components.
Importantly:
After that, the material is ready for application to concrete and other surfaces.
3. Applying epoxy paint to a concrete floor
Applying epoxy paint to a concrete floor is performed after the base has been fully prepared and the components have been mixed.
Methods of applying vapor-permeable epoxy paint Teknobond 620 :
✔ Roller — the main method of application. A velor or polyamide roller with a medium pile (8–12 mm) is used. The paint is rolled crosswise: first in one direction, then perpendicularly, so that the layer is uniform without gaps and overflows. Work in stripes, maintaining a “wet edge” so that there are no visible joints.
✔ Brush — used for applying paint in areas adjacent to walls, corners, around columns, pipes and other hard-to-reach places. The paint is thoroughly rubbed into the surface to ensure good adhesion and avoid non-painting.
During work, it is important not to exceed the recommended layer thickness, not to return to already dried areas and to observe the material's pot life when applying.
The drying time of the vapor-permeable epoxy paint Teknobond 620 is 24 hours. The material fully hardens after 3 days.
It is after complete hardening that the epoxy coating acquires maximum strength. The bond strength (adhesion) with concrete is 4 MPa, with metal - 3 MPa.
Wear resistance of industrial epoxy paint TEKNOBOND 620
The abrasion resistance of Teknobond 620 industrial floor paint has been confirmed in the laboratory. According to the results of the Taber abrasion test using CS-10 abrasive wheels, after 1000 rotation cycles, the weight loss of the coating was only 60–70 mg.
This indicator indicates minimal surface abrasion even under conditions of intense mechanical stress - constant movement of personnel, carts, equipment or regular floor cleaning using detergents. In fact, this means that the coating retains its thickness, integrity and aesthetic appearance for a long time without dusting or rubbing to the base.
According to the European standard DIN 53109 , such results belong to the premium class of epoxy systems with increased mechanical resistance. This confirms that the material is able to withstand significant operational loads without losing its protective properties. That is why vapor-permeable epoxy paint is advisable to use on objects where high requirements for hygiene, strength and durability of the coating are combined.
The vapor-permeable system is especially effective for:
✔ restaurants — where wear resistance and ease of cleaning of the surface are important
✔ warehouses and food production facilities — with constant mechanical loads and wet cleaning
✔ laboratories — where the coating must be chemically and mechanically resistant
✔ cold rooms — with temperature drops and condensation
✔ rooms with high humidity — where it is necessary to avoid delamination due to residual moisture in the concrete
If you need a durable, hygienic and wear-resistant coating, the Teknobond 120 + Teknobond 620 system provides a professional result even under high loads and difficult operating conditions of the premises.
Painting an industrial floor is a technological process that requires proper preparation, the use of a high-quality primer, and professional epoxy paint.
Teknobond 620 epoxy paint and Teknobond 120 concrete primer are solutions for objects where strength, moisture resistance, vapor permeability, chemical resistance, and durability are important.
