Photocatalytic paints for self-cleaning facades

Photocatalytic paints for self-cleaning facades

Nowadays, more attention is being paid to the eco-friendliness and safety of building and finishing materials. One innovative solution in this area is photocatalytic paints for facades. Let's explore what these paints are and why they can be beneficial.

What Are Photocatalytic Paints

Photocatalytic paints are a type of paint that possesses the ability to self-clean under the influence of light. Their uniqueness lies in the inclusion of special photocatalytic additives in their composition.

How Photocatalytic Paints Work

The working principle of photocatalytic paints is based on the phenomenon of photocatalysis. Under the influence of light, photocatalytic particles (often titanium dioxide) in the paint are activated. These active particles initiate oxidative-reductive reactions that break down organic pollutants, such as fungus, mold, and exhaust gases.

As a result, the surface of a facade painted with photocatalytic paint cleans itself from contaminants under the influence of sunlight and rain. This helps maintain the original color and appearance of the facade for many years.

Advantages of Photocatalytic Paints

Using photocatalytic paints for facades offers several important advantages:

  • Self-cleaning of the surface from dirt, mold, and fungus
  • Antibacterial and antiviral properties, suppressing the growth of microorganisms
  • Resistance to atmospheric effects, maintaining color and gloss of the coating
  • Improvement of the environment by decomposing toxic substances
  • Savings on cleaning and maintenance of facades
  • Aesthetic appearance over a long period

Thus, the application of such paints contributes to creating a safe and comfortable urban environment for humans.

Areas of Application for Photocatalytic Paints

Thanks to their listed advantages, the areas of use for photocatalytic facade paints are quite extensive:

  • Residential apartment buildings
  • Office and administrative buildings
  • Shopping and entertainment centers
  • Industrial facilities
  • Transport infrastructure (bridges, overpasses, tunnels)
  • Social facilities (hospitals, schools)
  • Historical buildings and architectural monuments

When used properly, such facade paints can solve several tasks at once - giving buildings an aesthetic look, easing facade maintenance, and making the urban environment cleaner and more comfortable for citizens.

Development Prospects of Photocatalytic Paints

Despite their existing advantages, the technology of photocatalytic paints continues to evolve. Scientists are working on improving the effectiveness of photocatalysts, expanding their range of action, and enhancing the adhesion of paints to various bases.

In the future, more durable photocatalytic coatings activated by both natural and artificial lighting will appear. Technological advancements will allow the expanded use of such paints in interior decoration.

The development of this innovative direction in the paint and coatings industry will benefit urban ecology and the quality of life for people.


Thus, photocatalytic facade paints are a promising solution that can elevate the external appearance of cities to a new level. Thanks to their self-cleaning effect, such paints help maintain the aesthetic appearance of buildings, reduce maintenance costs, and improve the ecological situation in cities. As the technology of photocatalytic coatings develops, their application in construction will only increase.
