HERMES Fassadenschutz HFS

Protection against rapid renewed infestation of the façade

When professionally cleaning façades, your customers will primarily judge you on the immediate result. A clean façade is nice, but we are not satisfied with that alone. To ensure that the result holds for as long as possible, we have developed the HERMES façade protection HFS. This transparent protective agent for building materials adheres perfectly to the house wall, penetrates into the pores and effectively prevents the rapid formation of new algae and mould. Your customers will be thrilled to see their freshly cleaned façade shine as long as new.

Note: Use protective agents for building materials carefully and sparingly. Always read the label and product information before use. We sell our products exclusively to traders.

“For professional façade cleaning, it is essential that the cleaning agents used are perfectly suited to one another and, together with the cleaning technology, form an ideal system. To ensure this, we at HERMES manufacture our own cleaning agents. Our research and development department produces efficient cleaning agents for our HERMES system. In doing so, we focus on continuous product improvement in order to make them even more effective, economical and versatile. So our quality partners can always be sure they are using the best possible cleaning agent for their façade cleaning company.”

Officially confirmed:
HERMES Fassadenschutz HFS works

In order to prove the effectiveness of our HERMES façade protection HFS, we had it thoroughly tested in the laboratory of the Materials Test Institute in Bremen. The result: significantly longer protection of the façade against renewed algae and mould infestation. See for yourself!

Note: Material testing was carried out under laboratory conditions. One day corresponds to about one month. Accordingly, a period of 0–4 years was examined.

Important notes


The main component of the HERMES Façade Protection HFS is an active substance which disrupts the metabolic functions of micro-organisms and thus prevents their spread (registration number at the Federal Institute for Occupational Safety and Health (BAuA: N-59107)

Cleaning performance

Independent studies have shown that HERMES Façade Protection HFS keeps a façade clean for more than twice as long as without the appropriate protection. This usually means three to five years in practice. The length of time the results will hold is ultimately influenced by a number of factors, which we show you here.

Safety notes

Use protective agents for building materials carefully and sparingly. Always read the label and product information before use. Keep out of reach of children.

Application notes

Ensure that the façade is completely treated during application, as the untreated areas may soon show renewed algae and mould infestation.

Our HERMES Fassadenschutz HFS has no influence on any subsequent new coating.
