Two types of products with photocatalytic properties are being developed. The first product type is a photocatalytically active screed on a cement base for application, especially on concrete substrates. The second type of product is a photocatalytically active concrete additive in powder form, which enables the preparation of concrete surfaces with a photocatalytic function. The squeegees are made in two shades of white and grey. There are different types of dry mix for concrete due to their application. It can be the type added to the entire volume of concrete or only to the surface part of the concrete. It is primarily intended for exterior application for self-cleaning treatment of building envelopes and for surface treatment of various structures, e.g. bridges, noise barriers, guardrails, and tunnels, where it is also expected to contribute to air purification. Under certain conditions, the prepared materials can also be applied in interiors, where there is an important market, especially in the healthcare sector.
