Vallejo grey primer

[Guest]

.5 as Dougie says will be OK. With a 20% thinning you may get away with a .3.


What airbrush are you using Dave ?


In the end it is best to experiment and see what works for your set up. Never used water.


Vallejo thinner has all the ingredients in it that the paint has. Thin with water and you


upset that balance. Polyurethene primer is first class. Actually assume that it is acrylic


polyurethene as that is the best. Thinners should be Vallejo 71.161. which is specially


produced for airbrushing. It has a helpful lubricator in it.


Just to say that all Vallejo products are compatible one to the other. The difference is


that they are made for specific use.


Pressure. I use about 15psi. But you just get used to using the equipment and the paint


products in your own way. best is to get an old plastic water bottle and just spend session


using different needles and PSI. Pays huge dividends.


Keep your airbrush moving back and forwards always the same distance from the object.


Perhaps 6" but circumstances do dictate. I chuck rules out of the window and make my


own preferences up but they do give a starting point. If you dawdle and do not keep


moving you will build up paint curtains which make drips.


Good fun all of this Dave but it is worth preservering and practising to get great


finishes which give great satisfaction.

But did it work?, Laurie is the master, I'm sure I learned most vallejo tips among others from him. He is an institution haha.
Good man Laurie.

Ha ha. You little devil Dougie.

I use the Vallejo polyurethane primer with a 0.35mm nozzle unthinned with no problems. You do need to give it a good shake before starting, if you look you will see a darker layer settled out at the bottom once it has stood for a few days.

I won't know till today buddy, I was in bed asking last night!

Totally agree with Laurie. Vallejo Primer can work well and uit results in a really smooth tight surface that helps show up any flaws to be corrected.


One thing to add.


When correcting any flaws leave it at least 48 hours so it really cures well to make sure the primer 'feathers' when you sand it.


I have now moved over the the unpronouceable Badger primer http://www.barwellbodyworks-shop.com/144-primer-under-coat?


It is excellent and can be sanded soon after spraying. Please note though, this too needs a surface clean of grease so please make sure you wipe then plastic with ipa before applying. I did not do so on the Swordfish and it peeled in a couple of places, the good news is that as it covers so well with a thin coat and sands so well it was really easy to correct.

[Guest]

I always wipe everything with ipa, if it's paint don't let it sit though

[Guest]

Totally agree Barry. If attention is given to all these details all will be right. Do not and nothing is forgiven.

Totally agree with Laurie.

So Barry I am now handing the mantle hung around my neck given by the cheeky Dougie to you with


two amendments. Ancient Mariner and the Albatross come to mind.


Barry (Laurie) is the master, I'm sure I learned most vallejo tips among others from him. He is THE institution haha.

I meant to upload this yesterday. 3 very thin coats within 15 mins and 10 hrs drying time as it was painted in the morning before work and when I got home you couldn’t scratch it off with a finger nail which is the opposite of a lot of people's experience. Its really quite nice paint just not as durable for sanding without a longer drying time.


Also this is the grey, yes for some reason their grey is just off white haha. I have both and the white is much brighter

Yep I spra... No actually there are too many connotations that will get me banned. ops:

I think I have a bad batch,


I tried to spray the primer this morning on some scrap, and ended up with blobs.


I borrowed my borers fine detail hvlp gun, which has a variable paint flow, and still this bottle of primer is horrid!


So I sprayed the tank this afternoon with halfords primer! I'm done with these expensive wastes of money, it's in the bin!

[Guest]

I'm done with these expensive wastes of money, it's in the bin!

First Dave using primer this way is the cheapest way that you can get. Halfords primer


is the most expensive. I have a 200ml bottle of grey primer which I bought 7 years ago.


I have used just over half and it is still in first class condition.


200ml Vallejo primer £7 Halfords spray about the same.


So there is either something wrong with the primer or your technique.


Take it you have other Vallejo Model Air paint ? If so then try airbrushing that on an old


water plastic bottle. Do not thin straight from the bottle. If OK then try some more but with


say 20% Vallejo thinners.


If that works then your technique airbrush thinners and paint are OK. You have a problem


with your Vallejo primer. Return it to who ever sold it to you for a replacement.


Just a thought especially as you were mixing enamels and acrylic thinners. What


are you using Dave to wash out and clean your airbrush. Hope it is not enamel or


Turps subs thinners. If so then that is probably the problem.


Next what airbrush are you using and also what compressor. Airbrush compressors


are oil less. If you are using an airbrush which is not made for airbrushing the


likeley hood is that it is an oil lubricated compressor. If that should be the case any


paint airbrushed will have a smattering of oil in it. That will also cause a


problem as oil and acrylics are not friendly to each other.


If none of this works ??**&^%^&**(()))(*&^%$%^&8.

I would also try adjusting the air pressure. A higher pressure may help. A thorough strip down clean is also advisable,.

[Guest]

Airbrush sprays all other paints perfectly fine, this primer is just globules of rubbish. I've tried 10psi all the way to 30psi.


As I said, I put it through a HVLP primer mini gun, which sprays primer perfectly, and it still spat, lumped and wasted my time.


I bought it from the same place as I got the Airfix models from, so I reckon the seller has VERY old stock and doesn't store stuff right.

Take it back Dave. If you have problems with the retailer email Vallejo Customer care they run a great department.


Be interested to find what the problem is Dave. Also add get the stuff on line from John shop he has a good roll over of stock all delivered to your door step in 24 hours.
