Full Version: Powdery undercoats - what the?

estel
A couple of hours ago, I started undercoating my newly purchased Tomb Kings with White Knights white undercoat.

As you may well have guessed from the title, the little mofos are powdery as hell now.
I've never had this happen before with other undercoats, and after hearing people rave about White Knight, this is my first use of it (using a new can may be part of the problem).

As I type, they're sat in a little metho bath in an effort to remove the offending undercoat.

The question(s) being - why did the paint do this, and is stripping and recoating going to fix it?

As I said above, it's a new can, so may not have been properly mixed, or the humidity here may have been a problem (although when I sprayed it didn't feel too humid) - perhaps a few factors conspired against me.

I don't know about you man, cause you live in the rich area of town, but it has been as humid as hell on my side of Rocky. I dare say this is the problem.

The proletariat are obviously rising in rebellion by ruining your precious spray paint.

Also, the white takes a hell of alot more shaking then the black.

LoL, i didnt realise there was a rich part of rocky, all i seem to see when im there for 2 days or so a year is that huge freaking cow. And why is rocky always deserted around christmas time, its like a freaking ghost town. Chances are it will be again when i come up in 2 weeks.

Your particular can could be stuffed estel, try spraying it when its less humid and see if that has any effect. Next time remember to test it before spraying your minis tongue.gif

Waargh, if you're up for a game, give me or Big Willy a PM, we can give you directions to the club, or just meet up and put a name to a face wink.gif (although neither of us have played 40k much of late)

If I want to wait for the non-humid time to paint, I won't touch this army until March at the earliest. wink.gif

Did you was the little buggers before you undercoated them? I've found with any white undercoat, it is very important to give the models a good wash (usually with a couple hours soak) in medium warm soapy water. Sometimes the mould release stuff really mucks up a model. In fact, I've gotten into the habit of washing the sprues first thing after buying new toys.

Most people aren't stupid enough to hang around rocky over chrissy. I wil be here though sitting on a large block of ice in my jocks with a XXXX in my hand and a paint brush in the other. If you want to come aroudn give us the heads up.

I've had the white undercoat go funky as well. I think it's a heat issue, with the solvent evaporating too fast. Oddly, I've never had a problem with the black.

Never used white knights spray but have had this problem with gw skull white spray

The simple answer is that it's too fucking hot to be anywhere near Rocky over Christmas. Although I'm alright now in my little unit in gladstone with sea breezes.

shake it up estel.....and I was told to immerse the can in warm water first as well, to make sure the pigment is fully disolved in the solvent...

yup, had it happen to me....always test spray before spraying models......

So the obvious answer is the paint is drying before it hits the model, humidity isn't the problem, your holding the spray can too far away from the figs and the paint is drying in the air before it hits the model, Lachy has the right answer, thse solvent is evaporating, that'd be due to heat not humidity.

Fix #1 Stray's got a good solution, warm water bath for the can prior to spraying is extremely useful - I have to do that in Brisbane due to similar problems.

Fix # 2 Spray when it is cooler, i.e. evening/early morning

Fix #3 Spray closer to the model, i.e. reduce the chance of the paint drying on it's way to the model

Fix # 4 For the fuzzy models you already have, give them a brush over with an old toothbrush - make sure it's not wet. This will act like a mild abrasive and take off the fluffy bits.

Hope this helps in some way.

Cheers,

What The..... ?!??!?! <horrible visions are now stuck in my mind> :|


I wonder if the WAU word filter picked this one up and changed the word to XXXX? ;-)


Or maybe he means Beer? I have been told that QLDer's can't spell, hence they use XXXX to label their beer ;-) tongue.gif

What GT said...... and also watch your models placement... the drying spray may be settling on your already sprayed models if they are close-by the next spraying........ giving a similar dried powderedy finish....

Keep already done one along way away and spray in less windy places...

what would I be holding in my hand that would be holding in my hand... ohhh. Well, maybe if I had three hands, that would be a fun time.

Back on topic... ummmm, spray paint is good.

I have problems with all spray. Nowadays, i give the models a quick going over (just enough to get rid of the plain plastic or metal), then a thinned gloss varnish, then a thin coat of black paint.

THEN i start painting.

The worst is when you've spent hours/many$$$ on a model, to find the black has gone grey and bubbly. Ergh.

The 4X means it's four times better tasting then Vomit Bombs.

This is the absolute best advice!

I've had it happen to me too. Like Murphy's law, it only ever happens when you don't test first and go straight to spraying on the models.

Yep - always, always test on a piece of sprue first. If possible, try it on the sprue that came with the particular mini, as I have found that the plastic tolerance to spraypaint varies between batches. Certainly, I've found that some marines, dark eldar and some 'nids were more likely to melt, whereas it seems that orks and catachans are more resiliant.

Certianly agree with you there... mind you, a lot of beers taste better than VB!

I've had this problem because of one of two reasons:

1. Too many models at once, hence the paint drying before it hits some of the models

2. Not shaking the can enough. SHAKE SHAKE SHAKE THAT... um... can....

I had this happen to a can of BLACK white knight and I couldn't believe it. It expected it from white then BLACK did it and I realised I didn't shake the can enough. After a good 10 minutes shaking it was fine.

BTW, I was using White Knights but I've now switched to Dulux. Seems to be better quality and for the same price. NICE!
