Tiny bumps in wicked colors

[kylegabbert]

Hello, I have been using wicked colors for a long time, and recently I started to notice that alot of times there are tiny bumps in the paint. Mainly with the wicked blue. I filter it, and have a water trap on the compressor. It is also reduced and flows correctly. Not sure what the problem could be

can you post a picture Kyle ?

is it always on the same substrate ?

Is it happening In the cup or on the surface you are painting on?

Will take a picture when I can, I'm thinking it may just be dry spray, but then again it doesn't happen with all colors. Is it just me, or does the wicked blue have horrible coverage?

Happens on the surface. I don't notice them until I finish spraying. I spray in light coats, is it possible to dry spray waterborne paint?

I had that issue with Wicked Detail Blue. It came out so grainy and bumpy. Are you Reducing with water or 4012? It could be the pigment is getting to old or even a contaminant in the brush. What are you cleaning with between colors?

Also blue is a pure pigment and a bit larger pigment then secondary colors, so it tend to clog a bit more often. It is possible that the blue is clumping a bit in the nozzle and the spraying out. I would try adding the reducer to the cup first the adding your reducer and letting it sit for a bit while you do other things. Also if you are rinsing with water between colors try running a pinch of reducer through the brush before you go to the next color.

I've not experienced horrible coverage with blue, apart from one time on a glossy surface where it appeared the paint was beading up a little. It had been fine with other colours, but a little less reducer, lower pressure and a tad more distance from surface and it was fine. Could this be what's happening?

Is it really hot where you are? That might cause the paint to start to dry before it hits the surface I guess.

I use 4012 and intercoat. It may be getting old, it's about 2 years old now. I'll get a fresh bottle to try. But the coverage over a solid white base of autoborne is horrible. It's blotchy, even when I do even coats.

Very hot here in South Tx. But no problems with any other colors

If the other colors are fine than it's an issue with the Blue. Is there a possibility that you have dumped paint with reducer back into the main bottle. Over time it could be evaporating causing clumps to form from drying to fast. Just guessing though.

As a matter of fact I did do that not too long ago. Will get more blue today and test it. Thank you

Yep that's a big no no. I started doing that with just water as a reducer years ago and that began to affect the paint flow and would make it gum up over time. That when I started using separate bottles that I could leave that paint in till it was no good which was usually three days or so.

Hi all
I thought adding 4012 to Createx and Wicked gave it a pot life ? is this true,

Nope when you add reducer it shortens the pot life of any paint.

I believe createx says CI and 4012 have a 72hr pot life.

Of course, rules are made to be broken. The "listed" pot life from any manufacturer is generally meant to protect the company from paying out on frivolous complaints. The pot life can be extended far greater than what they recommend in most cases. I've stretched the pot life with Createx products as far as two weeks or more in a sealed container without any issues.
