Concrete cleaning: rust and limescale removal

Rust and limescale efflorescence can only be removed with acidic cleaning products. Acidizing is a chemical process used to remove cement residue, chalk and rust stains. This process can be used to achieve color fastness, particularly with colored exposed concrete.

Here, too, it is recommended to treat cleaned exposed concrete surfaces with a concrete protection so that no pollutants can penetrate the concrete and the surface remains clean and beautiful at the same time.

Intensive concrete cleaning

Ordinary cleaning only removes dust from the surface. For heavily soiled exposed concrete surfaces, we therefore recommend intensive concrete cleaning so that pencils, marking spray, bitumen and other stubborn dirt such as algae and moss can be removed.

We recommend that you protect cleaned surfaces so that no harmful substances can penetrate the concrete and the surface remains clean and beautiful at the same time.

FAQ

Häufig gestellte Fragen

Kann man Betonplatten mit Hochdruckreiniger reinigen?

Ja, kann man. Wir empfehlen Ihnen, die Platten nachträglich behandeln zu lassen, damit die gereinigte Flächen auch sauber bleiben.

Wie bekomme ich Flecken aus dem Beton?

Flecken aus einem Beton zu bekommen, ist nicht ganz einfach, da der Beton eine saugende Oberfläche aufweist. Reinigungen auf Beton sollten Sie dem Profi überlassen, da sich die Flecken durch falsche Anwendung vergrössern können oder die feine Betonoberfläche beschädigt werden kann.

Wie bekomme ich Beton wieder sauber?

Abhängig davon, um welche Verschmutzung es sich handelt, gibt es diverse Reinigungsmethoden, um einen Beton wieder sauber zu bekommen. Wir helfen Ihnen gerne weiter.

How do traces of rust and limescale appear on concrete?

Rust can be caused by metal parts, runoff water or iron-containing entries. Traces of limescale and efflorescence are often caused by moisture, waterways and mineral deposits.

Can you remove rust and lime from concrete with acid?

Uncontrolled acid can attack cement paste, roughen the surface and change the color. BKOS carries out preliminary tests and adjusts the means, concentration, exposure time and neutralization to the concrete.

Can rust and limescale stains be completely removed?

Fresh superficial deposits are usually easier to treat than deeply embedded or long-standing discolorations. The realistic result is assessed based on a sample cleaning.

Do traces of rust or limescale return after cleaning?

Yes, if the cause such as water flow, corroding metal or permanent moisture persists. A sustainable solution combines cleaning with root cause elimination and, if necessary, a protection system.

Does impregnation make sense after special cleaning?

For absorbent and contaminated surfaces, coordinated protection can reduce renewed contamination. Whether it makes sense depends on the surface, appearance, moisture and use.

Can exposed concrete be cleaned with high pressure?

Only with controlled pressure, appropriate distance and after a preliminary test. Excessive pressure can remove cement paste, open pores and create an uneven cleaning pattern.

What dirt does intensive concrete cleaning remove?

Depending on the process, construction site residues, dust, atmospheric dirt, signs of use and certain organic or mineral deposits can be reduced. Oil, paint, rust or lime often require separate special treatment.

Why do some stains remain visible after cleaning?

Some substances penetrate deep into the pores or chemically change the concrete. In such cases, cosmetic adjustment after cleaning may make more sense than further aggressive cleaning attempts.

When should exposed concrete in a new building be cleaned?

Cleaning should be carried out after dirt-intensive work has been completed and with sufficient time before removal or protective treatment. Protective films, construction processes and sample areas help to avoid unnecessary rework.

Does cleaned concrete need post-treatment?

Not fundamentally. For exposed or heavily used areas, hydrophobization, impregnation or graffiti protection can make later maintenance easier.
