By spraying is (after drying, about 1 minute) produces a thin, transparent film that protects small wounds and scratches well against environmental influences, is breathable and also holds two days. Unfortunately, it is difficult to narrow the spray. I at least always sprayed far too great a surface. If you want to make sure that the actual injury is well protected, one must unfortunately with quite a lot of "wasted plaster" live. After all, can the excess sprayed plaster easily wipe. Also, the "fixed" patch is easy to remove. A good solution, if it's not supposed to be so conspicuous.
