That turned out great Silent. I'm glad I could be of some slight help.

... the value of masking cannot be overstated.   

Amen.

You live and learn...

This really is a brilliant build, I'm looking forward to seeing it painted. 

[Remington]

Well good thing you corrected that inexcusable, atrocious mistake... How could you?

 

But that is the way of the true perfectionist I guess. Can't wait to see it finished.

A belated thank you for the feedback which is very generous. 

I've moved on to the painting stage but when spray undercoating I forgot to mask the foam board 'boulder wall' and so parts of it were damaged by the solvent.  Fortunately, it was easily repaired with greenstuff but the value of masking cannot be overstated.   

I coat it my foam board with 2 layers of watered down PVA glue. I seals the foam and prevents that sort of thing.

the sides of the boulders and the crevices between were great, I just lost my rounded peaks!  )

Same thing happens to me when I make Meringues

Thanks for the feedback   

Thanks Rob, that is a top tip. 

I did give it one coat of PVA, as shown (still wet) in this image:

It would seem that my shortcoming was in not giving it two coats.

I suspect that, as it dried, the first coat shrunk away from the 'peaks' of the boulders to leave them unprotected, as it was these that suffered the damage from the spray undercoat (the sides of the boulders and the crevices between were great, I just lost my rounded peaks!  )

Yeah that stuff is porous as hell. The best way to check if you've given it enough coats I've found is to tap it with a tool, if you hear the click of a hard surface you're good. If not then you're hitting foam and you'll need more coats.

Looks great!
