Treating concrete walls instead of painting concrete walls

Lichens, algae and moss not only make a concrete wall look unsightly, they also damage the concrete wall. First, microscopic damage occurs, moisture penetrates and decomposes the concrete wall over the years. Brushing, scraping or painting the concrete wall is not enough. Experience has also shown that cleaning the concrete wall with a high-pressure cleaner and chlorine is more harmful than useful.

High pressure and chlorine or Javel water?

The reach for high-pressure cleaners, chlorine or Javel water is close at hand. Results are quickly visible and superficially the cleaned concrete wall is clean and free of moss, lichen or algae. But what the eye does not see, unfolds its harmful effects in the following months.

The high water pressure washes out the concrete. The barely visible damage to the surface provides a good foothold for new spores, so that mosses, algae and lichens gradually grow again. Each time the concrete wall is cleaned, new damage occurs and gradually becomes visible. But then it is usually too late and the concrete wall has to be repaired at great expense.
