skeletoro Posted June 17, 2013 Share Posted June 17, 2013 Hey there, I've been playing around with some painting techniques on practice minis, and just had my first try with oil washes today. Unfortunately while I was cleaning up the oil wash with a cue tip soaked in turpentine, it actually removed the paint under the oil wash too. I'd used the hairspray technique to do some weathering, and noticed that the turps was stripping the paint back to the metallic colour underneath the hairspray. My paint order was something like this: Metal colour Matt varnish Hairspray Armour panels colour Gloss varnish Oil wash Cleanup with turpentine. So I think what has happened is that the turps ate right through the Gloss varnish and stripped the paint right back to that first coat of matt varnish, exposing the metal. Does this sound likely? If so... I must have messed up the gloss varnish step somehow. How long do I need to leave a varnish to dry before messing with an oil wash? I gave it over an hour but I'm starting to wonder whether I should have allowed several hours...? It was Vallejo gloss varnish. I slapped it on with a brush because I wasn't able to fire up the airbrush at the time and it was just a test mini. I thought I was pretty thorough though! Any thoughts?

DarkMark Posted June 17, 2013 Share Posted June 17, 2013 I'd give any varnish at least 24 hours to dry before doing anything with it. Oil washes can take days, literally, to dry. Sounds like you were too hasty to me.

S.k.i.t.t.l.e Posted June 18, 2013 Share Posted June 18, 2013 Also I'd say that using turpentine instead of mineral/white spirits to clean it up is eating your varnish off. The two things are not the same. Even synthetic turps (often called mineral turps) is different. Try the mineral/white spirits to make your oil wash and to clean it off, should help. I've used mineral spirits to clean water based wash off models without varnishing and had no paint removal.

skeletoro Posted June 18, 2013 Author Share Posted June 18, 2013 ohh... didn't know there was a difference. It turns out I'm using mineral turps. I guess that means it's derived from petroleum rather than vegetables? That means it should be OK then, right? So I guess I was probably just a bit lax with my varnishing.

S.k.i.t.t.l.e Posted June 18, 2013 Share Posted June 18, 2013 I haven't tried mineral turps. But I'd recommend going with the white/mineral spirit instead anyway, its cheap as chips. But if you leave your varnish for a full 24 hours before washing and the cleaning up, it should be OK, as was said earlier. :) Link to comment https://bolterandchainsword.com/topic/276955-cleaning-up-oil-washes-removing-acrylic-underneath/#findComment-3396862 Share on other sites More sharing options...
skeletoro Posted June 19, 2013 Author Share Posted June 19, 2013 Thanks guys. According to wikipedia, mineral spirits/turps and white spirits are actually all the same thing? The only thing that's different is turps, which is a vegetable byproduct and more toxic/potent than the rest, which are made from petroleum. Also, apparently there's odorless mineral turps, which sounds quite nice ;P Link to comment https://bolterandchainsword.com/topic/276955-cleaning-up-oil-washes-removing-acrylic-underneath/#findComment-3397551 Share on other sites More sharing options...
S.k.i.t.t.l.e Posted June 19, 2013 Share Posted June 19, 2013 Yeah wikipedia.....Hahahaha. Mineral spirits is what the Yanks say, white spirits is what the Brits say. Same thing. Mineral turps is different. But whatever works for you dude go for it. Edited for better English...........You wouldn't think I was a Brit.

skeletoro Posted June 19, 2013 Author Share Posted June 19, 2013 Ah, looking at the talk page on wikipedia... http://en.wikipedia.org/wiki/Talk%3AMineral_spirits It looks like there is a bit of a difference. They're produced much the same way but mineral/white spirits tends to be a bit safer and less likely to do weird things to paint - mineral turpentine includes more aromatics and other impurities such as sulfates... so yeah. It could be that I'll have a much easier time with white spirits! At the local art supply you can get Pebeo brand odourless white spirits.. way overpriced though! Might try the supermarket...

S.k.i.t.t.l.e Posted June 20, 2013 Share Posted June 20, 2013 I use no-name-brand stuff from the local hardware store, just get the cheapest!

skeletoro Posted June 20, 2013 Author Share Posted June 20, 2013 At least as far as I can see online, none of the hardware stores have white/mineral spirits, only turps! D'oh. Unless I go to an art store and then it's NZ$60 per liter (wth?) Might have to try ringing around. Many stores don't have their full product list on their sites, so maybe I'll have some luck ringing.

DarkMark Posted June 20, 2013 Share Posted June 20, 2013 An art store or military modelling shop is your best bet for picking up these products. I know they're expensive, as in litre wise, but you'll only need a small bottle's worth. I use Ak Interactive's odourless thinner*, and it comes in a 35ml bottle for 4,5€ or 100ml for 7,5€. Unless you're going bonkers then that's plenty for casual use. *remember just because its odourless it doesn't mean it won't kill your brain with the fumes you can't smell. Hence, you'll still need to take all the usual hazardous substance precautions!

S.k.i.t.t.l.e Posted June 20, 2013 Share Posted June 20, 2013 I don't mind the smell of white spirit, thats why I just use any old stuff. Its all the same anyway. But if the smell does bother you then the odourless is definitely the way to go. Those prices don't seem too extravagant for the odourless type, DM, nice find. :) Link to comment https://bolterandchainsword.com/topic/276955-cleaning-up-oil-washes-removing-acrylic-underneath/#findComment-3397855 Share on other sites More sharing options...
DarkMark Posted June 20, 2013 Share Posted June 20, 2013 Yeah AK do a bunch of very good products, check out this showing a demo using a 40k tank. Skip to about 14 minutes for the bit about what we've discussed here. These guys have AK'ed their marine stuff here and here.
