Abstract
Smart inks as a redox indicators of photocatalytic activity were applied on several paints with acrylic and
silicate binder exposed to accelerated weathering test. The results show, that self-cleaning paints need
some weathering to develop full photocatalytic activity. On the other side weathering may negatively
influence the durability of the paint as shown for a silicate based exterior paint, which was significantly
degraded after 350 h of weathering test. Smart inks proved to be suitable and rapid indicators of paint
photoactivity. Resazurin ink is convenient only for unexposed paint with low photocatalytic activity
while an Acid Violet 7 ink was appropriate for most of the paints, especially those that were weathered
