Condensation

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

Condensation

I am still working towards my APA version of greenhouse sidings.....

Having got the 1:32 greenhouse ends 3D printed (Tebee), I find I need to blur with condensation the view through the "glazing",
to disguise the fact that they are only 10-15mm deep.

Suggestions please.

Haven't decided on what material for the glazing yet, but want a realistic representation, not a uniform "obscure".

Hi David,
Suggest you try PVA applied in small quantities to back of glazing then dragged vertically with finger - better done before glazing is fitted.
I've just tried it with a clear plastic moulding used to hold an off shelf model and it looks reasonable.
I used Wickes PVA and the more expensive Anita's Tacky PVA.
Anita's gave better result as it seems to dry more opaquely.
However it will very much depend upon what glazing material you use as to how the effect develops.
Give it a try, it can be made very random with clear twixt the opaque streaks.
So little time, so many ideas!!!!! GerryB.

Indirect exposure to Zap a gap and other cyanoacrylate glues can give a frosted effect to clear windows.

I know this because I foolishly used CA to secure cab windows in an On30 loco, and the gas given off in that confined space turned the inner surface of the clear window material frosted. In this case it was not the effect I had hoped for!!

If you were to try this on your green houses, do some testing on some scrap material, and of course be careful with handling the stuff. It could be difficult to control effects, but if you need random frosting it might just work.
