Washing Depths

Our products for the acidification of concrete surfaces facilitate nano and micro washing and/or acidification up to 0.05mm in new and old concrete. With deactivation, washing from 0.1 to 2 mm can be realized in exposed concrete. You can find details about washing depths in our brochure on surface retarders

Products

CemGel K

RECKLI CemGel K is a viscous washing gel for the attainment of the finest washing of concrete surfaces in positive processes.

CemGel KS

RECKLI CemGel KS is a viscous washing gel for the attainment of the deeper washing of concrete surfaces in positive processes.

CR Type N

RECKLI CR Type N is a solvent-containing concrete surface retarder for fine washing in negative processes.

CR Type PV

RECKLI CR Type PV is a dilute concrete surface retarder for fine washing in positive processes.

Negative Process (N)

01

The medium is sparingly and evenly applied to the form with a paint roll or a sprayer.

02

After a short trying period (15 to 60 minutes) the concrete can be introduced.

03

As a general rule, the elements can be washed out after 18 to 24 hours.

04

The minimum duration for the elements remainder in the form lies at 8 hours.

05

The washing out is most simply carried out with a high-pressure cleaner. Dry brushing out and subsequent washing is possible.

Positive Process (PV)

01

The concrete element is cast, the form is removed, and the element is smoothed.  Possible water puddles have to evaporate.

02

The medium is applied in one, well coating layer on the absolutely fresh concrete.

03

After the application, the concrete dries for 1 to 3 days.

04

As soon as the concrete solidifies, the form is removed.

05

The washing out is most simply carried out with a high-pressure cleaner.

Acidification (CEMGEL)

01

The undiluted gel is applied with a brush, water or sprayer on to the fresh concrete which is well moistened with water.

02

After the application, the product reacts with the concrete. The medium is distributed until it no longer foams.

03

The concrete element is subsequently throroughly sprayed with water.
