View Full Version : Polystrene
Does anyone have does and don'ts for painting polystrene blocks? Was thinking of spraying them with riugh coat to make a stone effect, will this be alright or will it melt the blocks?

by itself it will melt them, so give them a couple of good coats of pva/water 50/50 first then they be ok :)

oh hang on you mean texture coat? like sandtex, well i did try some by itself and it wasnt too bad, but to be sure pva it first

The same applies for gluing the blocks together, ensure a couple of coats of PVA and water mix if you are going to use superglue as the solvents in both spray and superglue react with the polystyrene causing cyanide to be released (not good) and the polystyrene will melt.
ok cheers folks. was worried I'd have to wrap everything in masking tape first. As a side note does anyone know where I can lay my mits on the wooden sticks you get in coffee shops?

Of course, the natural effect that comes out when polystyrene is melted by solvents is also quite an effective texture-provider :)
