Sorry Owen,but reading this article leaves us with a few misconceptions I
nead to dispell.His idea regarding weather and not being able to circumvent
it, is in my mind misleading.I live in South Florida where the temperature
is rarely below 70 deg and the humidity is almost always above 70 percent.In
these conditions I should not be able to use lacquer at all.The way to
overcome thus is by using lacquer retarder and make sure the compressor has
an in-line moisture filter.I use it everyday and have found these techniques
will overcome the moisture I have to deal with.Thanks,Rick

I am interested in finding out what the limits of humidity should be when
spraying lacquer on my turnings. I use an HVLP sprayer and spray
outdoors
in a 2 sided enclosed canopy but use a spray can for bowl repairs. I
have
been spraying for several years without any problems. That said, here is
a
problem I came up with yesterday. I was in the process of making some
very
minor repairs to some bowls that had been damaged by people handling them
during an open studios tour. It had rained the day before and early the
morning of my problem. I sanded the damaged area of a bowl then
proceeded
to spray it using a spray can of lacquer. As it started to dry I could
see
a haze building up, needless to say I now had to repair the repair. I
will
now have to remove the haze by sanding then re-spray the bowl, whenever
it
is safe to do so. I have used this process to make minor repairs many
times
before without problems, however; never directly or shortly after
rainfall
(rain started early here in my area). I am sure it is a humidity problem
but I am not sure of the solution/prevention for the remainder of the
winter
season. My question; at what humidity levels is it safe to spray to
avoid
this problem of hazing? Today, the humidity level is at 50% inside my
shop
Hi Ralph. Yes I believe your problems are moisture caused. Check out
