Polly scale colors troubles!

Posted by Anonymous on Thursday, July 8, 2004 5:38 PM

Polly scale you sure know how to Censored [censored]

my paint job! Angry [:(!]

I sware I'm not going to use them anymore!
What ever I do, nothing turns out O.K.!
I tried to delute the paint with distilled water, Alcohole (70%), IPA (IsoPropylAlcohol 91%), Pollyscales clear gloss, washing detergent . And any possible combination between them.
The result:
Always a dry tip within seconds(!!!) from the first blow of paint on a scrap piece of plastic. complete clog, air bubbles are returning back to the paint.

It didnt want to work with the PaascheI had, and it's NOT very friendly with my new Iwata either. Badger boys, I know you DONT suffer from that so please spare me the sarcastic (but I know they are friendly) remarks.

I work with Tamiya acrylics too, fantastic results!
Testors, Humbrol enamels, NO PROBLEM!
I work now with low pressure, so the paint is drying on the model and not while in the air.

Please help, I got important RLM colors and such, these are not-attainable-at-all here in Israel. and I got several projects on a stand still.
Got to solve this and move on!

P.S.

It dosent matter which color I use it's all the same.

Hum... I have used Polly Scale (formerly Polly S) almost exclusively for decades. I do use their brand of Airbrush Thinner however, as it is the glycol ethers that helps slow down the drying time, which sounds like the problem you are having. Perhaps some acrylic paint conditioner or acrylic retarder would fix the problem.

ahh man shahar, i hate it for you. i never could get PS to spray properly through any airbrush i've ever owned!!! i'm glad i only bought a couple of jars of it or would have been highly POed. if you have to do alot of tweaking and begging and junk to some product, i just leave it be and find something else. i've never had good luck with acrylics except for tamiya. but their color selection is very limited and i've had adhesion problems as well, even when i soaked the parts is soap and water and wrinsed properly. oh well, hope you can work it out. later.

I used PollyScale recently for the first time, I had great results. I was using my Badger 200. I think that I thinned it with the Tamiya Acrylic Thinner. Maybe give that a try.

Go to any good art supply store and get a bottle of acrylic retarder. It isn't always with the airbrush stuff, so look where they have acrylic brush paints. Common brands are Createx, Golden, FloQuil, LiquiTex (not sure about that name).

Thin your PolyScale using water and add a few drops of retarder. It will make the paint dry slower and thin is slightly so remember to cut back slightly on the amount owa ter you use to thin the paint. PS recommends 20% I think (it's printed on the bottle) and that's what I use.

If it still dries too quickly, add a couple of drops more retarder. The more you add the slower it will dry and the thinner it will get. When brush painting acrylics, I put a few drops of paint (maybe 6 or so) in a bottle cap and add a couple of drops of retarder. That effectively thins it about 3:1 and it will take several minutes to dry to the touch.

I used Polly through my ack...Aztek with no probs other then one coat I thinned too much. I just used water. I maybe making stuff up here but you eluded to the fact that you lived in Isreal. How is the temp, heat, hhumidity and otherwise there. All that stuff effects paint. the hotter and drier the atmosphere is in the enviroment being sprayed the faster the drying. You should check that.

Thanks for your replies guys!
Looks like Polyscale need a "royal treatment" in order to work properly.

Well in the mean time I guess I'll have to mix paints in order to get to the right shade and Hue.
Now I'll need to explain the art supply shops what I'm looking for...
They dont even know what an Airbrush is Dead [xx(]

and the one that know, never heard of anything else but Badger, and the only model he sells is some old single-action.
Go figure the ignorence... Dead [xx(]

Retarders aren't just for airbrushes. There are brush-paint arcylics for artists as well, and they use the retarders to.

If you can't find it, let me know. I'll send you some of mine.

I missed that part of your answer for some reason... Blindfold [X-)]

Well, I do live in the southern part of Israel and most of the time the air is dry and the temperture are high, this time of yeat.I guess it's that desert around here Wink [;)]

I paint in my room and at days like this the aircondetion is always on and the window is open, because I dont have a spray booth (...yet). So I have circulation of air, and a much cooler place from the outside.
Maybe this combo is a killer for these pollyscales? Black Eye [B)]

Dry air and high temperatures will probably cause the fast-drying problem of acrylics to be even worse. Just like anything else that evaporates quickly in dry air, the solvents in paint do the same. Since acrylics are already difficult to use because of the fast drying time, the weather there is probably not helping the problem at all.

Polly Scale does have a habit of "chunking up" if the bottle is not brand new. Stir the Paint well. A retarder will help and I do use a Badger . ;)

I have that problem with most acrylics. Let them sit for a month or so and there is a chunk of paint in the bottom of the bottle. I came up with this idea for a stirring stick that has worked very well. I make them from 1/32" music wire bent over the tip of needle nose pliers, and just large enough to fit into the bottles. A piece of heat shrink tube makes the handle a little bigger, and I just spin them between my fingers. They will break up a chunk or paint easily and really do a good job of stirring.
