Decola glass and ceramic paints are water-based, so they don’t have any unpleasant smell, like lacquer-based ones. For application you’ll need a quite soft synthetic brush as consistency is semi-translucent. We recommend having 2 coats of paint as just a single coat doesn’t have enough coverage and a bit seen-through. It’s always better to use light colors first for the same reason. As an advantage, you can achieve great glazing effects with these paints.
