DALL’EFFLO is particularly suited for the final treatment of exposed concrete surfaces, such as : Grey or white smooth concrete, washed aggregates, architectural concrete, tinted concrete, etc.Experience shows that best results are obtained when applied on concrete that has been poured for 20 or 30 days. This time is necessary for carbonation evolution. It is better to wash after this period to preserve the clear appearance of the concrete.

DALL’EFFLO can also be used for cleaning calcium deposits from all non-metallic supports, such as crockery film, glaze, plastic, etc. It also suppresses micro algae incrustations on these supports.


DALL’EFFLO must be diluted in a proportion of 100 g/l. In difficult cases, it is possible to increase the proportion to 150 g/l. The diluted solution can be applied on previously wetted concrete, with a brush, sponge or a sprayer. After 5 or 10 minutes of exposure time, it is necessary to rinse out abundantly.For cleaning concrete facades with DALL’EFFLO, please consult our specifications note related to this use.

Before any use, see the list of materials on which DALL’EFFLO can be applied without danger. Specifications note approved by SOCOTEC N° 93.008.7604
