Valleyofvallejo Posted September 14, 2017 Share Posted September 14, 2017 AFAIK, the difference is that the polyurethane varnish is more durable & dries quicker. But can the polyurethane varnish be thinned with water or acrylic thinners? Does it yellow or brush well? Link to comment Share on other sites More sharing options...
Black Knight Posted September 14, 2017 Share Posted September 14, 2017 I use the polyurethane varnish; can't say about it yellowing yet. Out of the bottle I find it thick and doesn't brush out well, it dries very fast, so I thin with water, about 1:1, maybe a bit less water than that Link to comment Share on other sites More sharing options...

Ade H Posted September 14, 2017 Share Posted September 14, 2017 I assume that you are asking about the Premium varnishes, as these are the only poly varnishes still in production as far as I can tell; the others are resin. I spray them neat; but if necessary, they should be thinned with the Premium reducer. Airbrush thinner can be used as well (and I have tested this), but water is not recommended. Vallejo also advises that excessive thinning will weaken the varnish's properties. Link to comment Share on other sites More sharing options...

Ade H Posted September 14, 2017 Share Posted September 14, 2017 (edited) @Black Knight Are you using something other than Premium, eg. those old-style bottles with the white labels? Vallejo advises against water (and probably this applies to all the poly products, but I didn't ask). Edited September 14, 2017 by Ade H Link to comment Share on other sites More sharing options...

Ade H Posted September 15, 2017 Share Posted September 15, 2017 I see, that's the old product to which I alluded yesterday. I believe that it's discontinued because it disappeared from the catalogue quite some time ago and the only poly varnishes are the Premiums.

Also available is the standard Acrylic varnish in Matt, Semi-gloss and Gloss that are in 17ml and 60ml bottles. Link to comment Share on other sites More sharing options...
Ade H Posted September 16, 2017 Share Posted September 16, 2017 It may still be on sale somewhere, but as I said, it's not in the catalogue, so I could not find any instructions for it. Other than what the label advises, pretty much the only sources of instructions or info about it now would be to ask a stockist or, if they're not sure, contact Vallejo. I have done that before and it is responsive to questions. Link to comment Share on other sites More sharing options...

I have done that before and it is responsive to questions. It is listed in their current catalogue that is able to be downloaded directly off the Vallejo website and is dated January 2017 ( CC75-Rev.15 ) and is on page 85 on the Auxiliary Products. I am able to purchase it locally here in Australia as it is in production and easily available from our local distributor. Additionally I found the product listed on the Vallejo website as you click on the drop down list at the upper right hand side of the main Vallejo website and choose Auxiliary from the Fine Arts and you will get a long list of products that includes the Polyurethane range of vanishes. And in the UK the distributor is Creative Models. Edited September 16, 2017 by Mick4350 Link to comment Share on other sites More sharing options...
Ade H Posted September 16, 2017 Share Posted September 16, 2017 (edited) Well, whatever, but it's not in the copy of the catalogue which I have and it was removed from the model paints auxiliary section on the site.

Mick4350 Posted September 16, 2017 Share Posted September 16, 2017 Then maybe you should download the current catalogue and see that it is there for sale ! Link to comment Share on other sites More sharing options...
Mick4350 Posted September 16, 2017 Share Posted September 16, 2017 On the instruction on the three bottle of Polyurethane varnishes it states, " Waterbased polyurethane varnish. permanent and very resistant. Dries to touch in one hour. To achieve a uniform coating, apply 2 coats of varnish in 4 hour intervals. Clean up with soap and water. Can be used directly with airbrush of needle size 0.4mm without dilution. " " Chemical composition: Polyurethane polymer dispersion. " Link to comment Share on other sites More sharing options...
wildman Posted September 19, 2017 Share Posted September 19, 2017 I use the vallejo airbrush thinners to thin mine out for both brush and airbrush application. Seems to work ok and haven't had any issues. With regards to yellowing, can't confirm or deny as the oldest model I have that is varnished with this stuff is only 6 months and it's still in pristine condition Link to comment Share on other sites More sharing options...
