Technical Documentation
Additional useful information

The OTTO Smoothing Agent may be diluted with water. When using smoothing agent, water stripes that occur must be removed immediately. If not cleaned till later, this may result in permanent streaks.

Do not allow residual smoothing agent to dry out. Larger quantities of smoothing agent should not remain on the silicone joint and start to dry out on top of it because these residues may impair the optical appearance of the sealant surface (dull/light patches).

Before use, preliminary tests should be carried out to ensure the compatibility with adjacent surfaces, for ­example different types of coated wood.

The dermatologically tested ingredients of the OTTO 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 creamed after use.
