Lacquer dulling LOS patina


#1

I recently purchased an aerosol lacquer called Permalac to seal my
LOS patina on my keumboo pieces. I was able to get some really
beautiful colors in the patinas but as soon as I sprayed on the
lacquer the colors went completely dead or disappeared all together.
All the lovely ranges of reds, purples and blues turned a dull
copper brown. I called the distributor but they didn’t have any
suggestions. Can anyone recommend another type of sealer that does
not dull or change the color or has anyone had a similar experience
with this product?

Thanks,
Grace

Grace, I use the Permalac with excellent success, but I do cut it
generously with lacquer thinner, in order for it to dry within a few
minutes to prevent dust and fuzzies in the finish. Several dips is
enough. Perhaps there is something in the aerosol propellant that
affects the process? Donna Wilson uses a spray lacquer made for the
auto finishing industry–the clear coat spray.

You might also look into cabinet grade lacquer (it will be a very,
very light honey blonde color), from Woodworker’s Suppy, or
Renaissance Wax for a satin sheen.

I’ve experimented with LOS patina and sealers. I took 6 different
cans of spray and wrote down my results. I started with 3 sets of 6
pairs of silver leaf earrings, each set of 6 pairs with the same
patina color, but each group of 6 pairs was a separate color
(magenta, dark blue and green). I found that some backed down the
color (I was using the patina with ammonia and salt added which has
a predictable color progression) 1 color, some backed it down two
colors and one left the irridescent colors alone but changed the
base color slightly. (Progression: gold is the first color, magenta,
then dark blue, then lighter blue and finally green) The best 3
sealers I tried were StaBrite brass sealer, Auto clear top coat (for
car, not truck…there were two kinds) and Nicklas which has more of
a mat surface. I never got a brown color with this process. I only
ended up with colors that I usually get with LOS patina.

I use a hard car wax spread thinly and polished with a soft cloth
when dry.

Donna, would you mind elaborating a little on your response. Was
Permalac one of the lacquers you tried in your experiment and if so,
did you use the liquid or the spray and what were your results? I am
not sure I am reading your results correctly - - did you get color
change with the clearcoat or Nickolas products and are they sprays or
brush on liquid? I am also curious what other products you found that
failed and did any of your experiments include LOS patinas where no
salt or amonia was added?. I thank both you and Katherine for your
reponses and help. Either of you are welcome to contact me offlist if
you desire to further elaborate. Grace
