Vallejo Satin Varnish?

[Adrian "Marvel" Reynolds]

Hi all,

I picked up some of this to coat my Saturn V with, when I've got it home it says on the side to brush it on, I was wondering if anyone has ever sprayed it? It's pretty thick so would I thin it with water?

i doubt you can thin it with water properly.....its a polyurethane

I have tried to airbrush it with 50/50 water mix, but it did not spray well, it does however brush very well when used neat, and does not leave brush strokes. Dries quickly, you need to give it a good stir. Derek

I always sprayed it without problems...in fact, this afternoon I have done it again

And I never thin it

Heck it's a lot of brushing, the kits 5 feet tall !!!!

I wouldn't like to try and brush paint an area as long as five feet but I'm sure you can get a thinner for it

All Vallejo products are thinnable with Vallejo thinners.

It is also water based product. Problem is thinning with water its loses stickability as the paint vehicle is diluted the paint losing the ability to flow free as it would with a proper thinner. Thinning will also take it into a matt basis.

As Polux not had any problem in airbrushing Vallejo. Prefer the Acrylic version as it dries quicker. Found the polyurethene takes twice as long. With the Acrylics I manage to double coat in two hours.

Thanks Laurie, times not an issue as I'm not rushing this build, I still have it in sections so I can spray a few then work on other sections then move onto the next bits as it dries. It states 4 hours between coats so it will be a few days of work

One thing Adrian if you are airbrushing. Make sure of a deep clean immediately after use as it is the best material produced for gumming up airbrushes.

Even Vallejo had not realised this product had this inane ability to make model makers very unhappy.

Polyurethane is an oil based product, so I doubt it would be a good idea to mix water with it.

This would curdle the mix & would be a definite no-no through an airbrush, as well as affecting the curing.

Hi Gregg this is the description below as given in their Q/A download.

It is a water based product, an acrylic resin polyurethene, so there will not be a curdle effect. I always wash the airbrush in water and have not had any problems.

10.4. What is the difference between the new polyurethane varnish

–refs.62.062 , 063 & 064- and your acrylic varnish?

The most important advantage of this new polyurethane is its superior strength

and resistance to nicks and scratches, which makes it ideal for surfaces

exposed to wear. The varnish is manufactured with a new resin of 100%

polyurethane which is self-leveling and offers a stronger protection than acrylic

varnishes. Basically it has the same properties as our new Polyurethane

Primers, can be applied with a brush or, for airbrushing, and diluted with our

Airbrush Thinner (Ref.71.061). Utensils can be cleaned with water after use.

I use this together with their airbrush thinner and it works very well in the airbrush.

As for it taking longer to dry, I have never really noticed. I tend to leave things alone for a day once varnished.

I have not noticed any degradation of the finish be it gloss, matt or satin.

Thanks guys, always good to learn something new.

All the polyurethanes I have had experience with were always oil based, which are not compatible with anything water based.

Just proves to myself, that since I had to retire from my trade I have lost touch with paint technology.

I retract my post unreservedly!
