This is hardly surprising as VDB is one of the variants of the kallitype
process.

Problems of coating can usually put down to the paper with which one is
working. I have found that the most consistent results for all the
'solution' processes can be obtained with Saunders Waterford and Fabriano
Artistico papers. I also found that adding wetting agents exacerbated the
problem of uneven coating. A 1 % gelatine size provides even and
consistent results.

Whether one uses a rod, a foam applicator or a brush is a matter of
personal taste. For me a dampened hake brush is the most effective tool.

Incidentally I am grateful to Judy for introducing me to 'maven'; a very
useful word.
