I have bought a couple of Verlinden plaster buildings and would be grateful for any advice on their construction and finish. The surface detail is weak but I know it is possible to get some excellent results, I just don't know how!
Any advice welcome.
You can glue the buildings together with PVA (white) glue; you may need to support them until the glue cures, but the bond will be strong enough for modelling purposes. If the detail is weak, you can fairly easily enhance it with some or another pointed object a needle, a knife blade, a nail, etc.
The plaster material sucks up paint, so you'll need quite a lot of it and can't really do any wet-on-wet blending or washes. If these are your normal painting techniques, you may want to try and seal the plaster before painting it; I suppose a coat of thinned PVA glue will accomplish that nicely, but I haven't tried it myself.
