steve45 Posted May 17, 2020 Share Posted May 17, 2020 I'm just about to start a JS Models warehouse kit and want to paint most of it before I assemble it with pva, I haven't assembled a laser kit before so I'm looking for advice on what type of paints to use. Many thanks Steve Link to post Share on other sites More sharing options...
Phil Parker Posted May 17, 2020 Share Posted May 17, 2020 Any paint will be fine. I've just built one of the warehouse kits for the July issue of BRM. If you aren't sure, test some paint on a spare bit of fret. 2 Link to post Share on other sites More sharing options...

steve45 Posted May 17, 2020 Author Share Posted May 17, 2020 That looks really good Phil, without giving too much away before BRM is issued, what did you use? I promise to buy the issue, when is it released? Link to post Share on other sites More sharing options...
Phil Parker Posted May 17, 2020 Share Posted May 17, 2020 Sorry - Phil's special stone painting technique must stay under wraps until 12th June when the digi edition comes out... All I can say is that there are several steps, nothing exotic in the way of materials and you shouldn't listen to Mr York's suggestions. Link to post Share on other sites More sharing options...

Many thanks Steve Steve, Sorry, I've only just seen this! I don't bother priming them myself, and just apply acrylic paints directly to the MDF. If you want to prime them, then a light coat of grey (or red, if it's brick finish) primer from a rattlecan will suffice. 3 hours ago, boxbrownie said: Would not a dilute wash of PVA over the finished parts be good for sealing the wood grain and give a good key for paint? I would not recommend this - unless it's a specific type of PVA designed for the purpose (which most modelmakers are unlikely to have knocking around, as they're not generally available) then PVA is generally a very bad medium for sealing anything. 9 minutes ago, Georgeconna said: I'd probably use a coat of Sand n Sealer on these.

Jonathan JSModels I didn’t know the lasered material was MDF I had assumed it would be a thin plywood, but I would be interested to know the reason normal (building) PVA would be not advised as a sealer, as we used it for years in the studio on architectural models?

I'm not an expert on adhesives by any means, but as a cabinet maker I've had to use quite a few different types, and learn about them. Normal PVA (and by normal I mean generic 'wood glue' types, classed as D2 adhesives) dries by evaporation of the water content, or absorption of same by the materials it's bonding. That in itself is fine, but if that dried PVA is ever exposed to water or high moisture levels it re-absorbs some water & becomes 'live' again; once this happens, it can never fully dry out to it's previous hardened state again and stays slightly soft. An example of this is removing old track by re-wetting the ballast, it becomes soft & easy to remove (if you then leave the clumps of removed ballast to 'dry' again, you'll notice it's much weaker than before & crumbles in your fingers). Moisture resistant PVA (D3 or 'weatherproof' PVA) is better in this regard, but still not great (there's an explanation of wood adhesive grades here). So if you seal something with PVA and then apply water-based paint over the top (often in washes for weathering) then you're breaking down the structure of the PVA. To be perfectly honest, for models it probably doesn't really matter, but I've just heard so many stories of things failing because people have 'sealed' something with PVA that I have an in-built aversion to it! I'm sure it'd be fine, but it's an additional, unnecessary step, so why bother? Jonathan JSModels 2 Link to post Share on other sites More sharing options...
