Vallejo Surface Primer

[Guest]

I just got a bottle of Vallejo surface primer and I don't know much about using it. I need some help from someone who's used this stuff before. Are you thinning it? If so I assume you use Vallejo thinner. What pressure do you get the best results? I'd appreciate your input. Thanks.

Ray. You can spray unthinned at around 20-25psi. Some people do thin it a little but it's not essential.

Wipe the model with ipa first to make there is no grease.

Spray a very light mist coat followed and build up your coats.

Do not mask over it for at least 24 hours or ideally 48 hours. If you are going to sand it to correct flaws leave it 48 hours because then it's cured enough to feather.

It is excellent stuff and cures to a tight hard smooth finish.

I have trouble spraying it through a .35mm needle, to date I've thinned with mixed results but usually end up with a blockage. The next time I use it I'll spray with a .5mm needle on an old airbrush.

I cannot add to Barry's post. I spray unthinned at abou 25psi with a 0.35mm needle with no trouble at all.

Similar to Barry Ray.

I normally wet and dry just to give better adherence. I use a .4 needle/nozzle at about 18PSI. Mist coat 30% thinned Vallejo thinner which has "stickability agents in it.

Second coat about 20% thinned.

Found there is a propensity, if I do not wet and dry, for the paint film to strip with a lot of masking. Just broke my own rule and actually did that &%*$".

Agree entirely with Barry on the 48 hours. As with all acrylics they are plastic films. If you try sanding before it is well cured bits of the plastic coating will tear off leaving crater type edges on the tear line virtually impossible to hide.

If using Mr Surfacer 500 best to do all the filling before priming as the Mr Surfacer softens the acrylic.

Great info guys. I'm off to give it a try. I'm a little nervous because my airbrush has a .3 nozzle on it and most are using a .35 and above. I guess I'll see what happens. May the priming spirits be with me.

i would make sure you thin. Try 35% Ray. Matter of experiment with a 0.3 needle nozzle.

Laurie,

I was thinking the same thing but had no clue where to start. Now I do. I'm in a conundrum my good airbrush has the 0.3 nozzle and my average brush has a .2 but I can change the nozzle in it to a 0.3, do you think it's worth the time and effort or should I just shoot it with the good gun?

I would use your best brush Ray. Provided you use Vallejo Air Brush Cleaner to give it a good clean out you should be OK.

Thinking, some times do, if you are still having blockages I would try upping the PSI 25 say then 30. All a matter of experimenting before you hit the real target.

This is a decent video Ray, I don't use Vallejo myself, but these chaps make it seem easy !

Not viewed it yet but one thing is clear from the title page. Both Barry and I have said if you are going to sand Vallejo primer then leave at least 48 hours. They talk of 24 hours and as they say sanding will strip the primer.

After 48 hours I happily wet and dry WET and have not had any problems. One thing not to do is apply anything other than thin coats. Thick coats will take a proportionately longer time to dry than 48 hours.

Had an experiment yesterday. If you strip by accident a bit of primer it will have crater edges near impossible with filler to disguise. Tried carefully with success with a brush and Vallejo Airbrush cleaner flattening the edges. Also using a sponge thinghy gives results.If not cured well try Vallejo Thinners. Make sure the affected area is cured before working on it.

You should save your money & buy this stuff! 300ml from the Poundshop & it dries back really tight, even if you're heavy-handed and put it on too thick.

The best thing is that it can be handled in less than an hour without fear of it coming off (unlike Vallejo) & after 3-4 hours can be sanded.

After 24 hours, a fingernail won't make a mark on it!

I will get some Patrick and test it against Vallejo primer.
