The scenery is all set for painting, we have already pre-sealed everything! The material takes paint really well but because I work mainly with the airbrush I like to start with a black undercoat and work up through the colours to brightest, let the black work for you with shading! I have always steered clear of the expensive 'modelling' sprays and found that Matt Black acrylic auto spray is perfectly good for the job and usually much cheaper!
Each scenery piece is cast using high quality Alpha grade casting plaster with a resin additive for extra toughness. This is one of the highest rated plaster materials made with a special formula. It is a very hard, white 100% Alpha plaster for use where high strength and surface hardness and durability are important. This is a much harder material than resin that holds great detail and does not suffer from bendy sword syndrome. Every scenery piece is cast by hand so may contain small air bubbles or imperfections that can be solved with a little TLC.
We wouldn't recomend treating any of your collection like this whatever it is made of, but this video demonstrates that the material isn't as delicate as you may think.
This material usually repairs seamlessly, I know, I have dropped plenty with my butter fingers and just watched one of my new rivet wars trains bounce down the stairs, now repaired with the aid of the good old superglue and a lick of paint...good as new!
