lacquer-voicing

[David Love]

Horie:

Eric had indicated that the relevant number was the % solids and that
the solution should generally be diluted down to 3%.  That would mean
that a 26% solution would be diluted by over twice that of a 12%
solution in order to achieve the same result.  That was the question I
believe Tom was asking.  In actual practice, it appears, at least from
my experience, that a 26% solids lacquer should be diluted about the
same as the supposedly 12% lacquer that is being used in New York.  I
suggest either their numbers are incorrect, or there are other factors
at play that contribute to the densifying effects other than the %
solids.  That being said, it's probably wise to experiment a bit with
the lacquer you have to determine what sort of dilution is most
effective.

It is not supposed to do a lot in that kind of solution.

Cheers.
