I have been using my Turbinaire HVLP sprayer for about 8 months now and
have been quite happy with the results. However, I have been trying to
use Fuhr WB urethane on a table top with less than good results.
I was getting large bubbles trapped in the finish. I called the
supplier and subsequently applied half as much per coat and used more
air. This gave a definite improvement but now I have small bubbles
trapped in the surface. The RH in the shop is about 30% and temperature
is about 20 (68*).
I have used it straight and diluted about 10% with water giving what I
think are the same results. So, any ideas on how to get rid of the
bubbles? Thanks, JG
just realized I implied I haven't used the flow modifier much; what I
meant was I haven't sprayed MANY projects, but those that I did spray, I
used the flow modifier each time, with GREAT results.

Hi Rumpty,
Everything is at the same temperature. As to stirring, the material is a
"satin" and as such has a lot of flattener in it. The material in this
particular can settles out quite quickly so I have to stir it and use it within
a few minutes. JG

Hi Mike,
I will get them to include some retarder in the next order. Thanks, JG

Just call me a throw-back; I'll stick with the Enduro, thank you very
much! :)

Dave,
Hydrocote used "flow modifiers" 15 years ago with their products. These
days you don't need them with Hydrocote products, and their Hydrocote
Resistane sprays just like a traditional lacquer. You really need to try a
good WB product..

I opened a new gallon of Hydrocote Resistane satin that was made in 4/03 so
it really needed to be stirred. I had a bunch of bubbles stirred in. Upon
application the Resistane flattened out fine with no bubbles trapped.
Two suggestions, they had a bad mix with the gallon you are using, OR your
gun is dirty and causing a problem. The WB product takes extra effort to
keep the gun clean.

Several but they would all entail being with you to see what exactly is
happening. Since we can't do that I'd suggest contacting the maker and
seeing if they have or can recommend a retarder to increase the time the
bubbles have to work themselves out of the finish.

If you the consumer has to fiddle and add retarder, yes. In it's early days
Hydrocote had to use retarders too, that hasn't been needed in 15 years.
Someone here is behind the times in technology. I shoot Hydrocote Resistane
every week and I shoot under some pretty lousy conditions at times and the
stuff performs.
Why should you have to be the chemist???????
Get with the program Dave! ;-)

Question, how much are you stirring prior to application? Also, is your
finish the same temperature as the work piece and surrounding air/workspace?

It sounds like you are laying on too thick a coat.

don't know about that brand, but the WB urethane I use, (Enduro) is
reduced with a flow modifier; NOT water...YMMV. It is useful for both
cold and warm spraying environments. I haven't used it a lot, but what I
have sprayed has ZERO bubbles in the finish (mid 60's temps and humidity
around 75%)
