Technical Documentation
Additional useful information

The OTTO Marble Silicone Smoothing Agent must always be used undiluted. It is advisable to use the smoothing agent sparingly.

The smoothing agent used should always be new and without impurities. To prevent stains/discolouration on the natural stone, remove excess smoothing agent with clear water before it starts to dry. Matt-finished colours have to be rebated dry, in order to keep the matt-effect on the surface.

Nevertheless, owing to the unique character of natural stone, stains/discolourations cannot be ruled out completely. Because of this and the many possible influences during processing and application, we advise carrying out preliminary, object-related tests.

The dermatologically tested ingredients of the OTTO Marble Silicone Smoothing Agent have been rated as “non irritating to the skin” by the Fresenius Institute, Taunusstein, Germany and therefore do not, unlike washing-up liquids, dry out the skin. Nevertheless, hands should be washed and re-moisturized after use.
