[Woodcarver] help needed

Diane,

You have probably 2 problems here.  Lacquer and varnish do not
mix.  Lacquer will eat up the varnish.  It would require a coat
of shellac between the lacquer and varnish to have a good finish.

The "white" you describe sounds like a condition known as "blush"
and is a common problem with lacquer which is applied in a humid
environment.  A lot of times, another coat of lacquer will take
the white away.  Normally, lacquer applied over varnish will
cause the varnish to crinkle but could cause a reaction where it
turns white.

Thought for the day: "Work fascinates me.  I can sit and look at
it for hours on end."  



> I just did some recarving on a bark piece and had to refinish the new parts.

> I used a coat of polyurethane on just the newly carved areas and it was fine

> in to dry out: no change after 3 or 4 hours. Next I brushed the white spots

> with a wire brush and most of the white stuff came off leaving those parts
