Small damage
15.6.3.1
General
Small damage is a deterioration of corrosion resistance. At repair the situation is made more
difficult by the fact that the substrate for repair coats is not a compact surface of basic
material but mostly al coats of surface protection (after sanding), of which not al are suitable
for (in ageing stage) for good adhesion of paint coats. Therefore we recommend to carry
out such repairs by a verified system.
Before repairing it is necessary to differentiate the type of the existing topcoat, single coat
and two-coat (with the top coat). For repair it is necessary to follow the used type of color.
It is suitable to choose the delimited area (e.g. connection of sheets, wing edge) for the
scope of the place, which is being repaired transition, is then better blended. In the case
that it is not possible to choose the area in this way, it is necessary to take into consideration
the higher difficulty of the procedure as for the uniformity of shade and elaboration of coat
transition.
