Hello,

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
(garage).

Any help you can give me will be greatly appreciated. Thank you in
advance.....Ralph

Hi Ralph. Yes I believe your problems are moisture caused. Check out

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

Piggyback - shellac fanciers move to slower alcohol like isopropyl in the
extremes.

Before you resand the area, try covering it with cotton cloth and using a
hot iron or
heat gun. This will SOMETIMES pull the moisture out. It usually works to get
moisture
rings off tables. Just be careful not to melt the finish.

Thanks to all, I will check Woodcentral out for their article, also I have
thought of using retarder but will have to experiment with how much. Any
thoughts on this? Thanks again....Ralph
