Piles of Rubble

 Hi Boomerang.I stumbled onto A company, "build-a-rama" , & started browsing.It's the same company that makes that uniform camo in decal form.I think it was through HLJ,but am not sure.Their web site is    www.BUILD-A-RAMA.com   .Well what they have are small[ but not to small,considering the low price] of mixed bldg. debris.small slabs of brick,rubble,reinforcing concrete wire& other bits of stuff you'd find in a pile of rubble.It's worth a look at.   rudedog

  Thanks for your advice everyone. I remember a long time ago when i was into model railways, i would drip diluted white glue into the track ballast when i was laying it. It worked a charm and held together well so thats what i was going to try with my rubble and it seems to be the most popular suggestion here. I will have another crack at it, experiment and see how it goes.

Gluing each piece of rubble separately takes way too much time. Get a small, pump spray bottle at a dollar store or reuse a old one. Mix a dilute solution of white glue (10 parts water :1 part glue) add to sprayer, plus a drop or two of dish soap. Pile the rubble where you want it, spray until wet, then let dry. Done.

You can also touch up any areas with a eye-dropper, dripping small amounts wherever needed.

I use a 60/40 mix of Elmers (white) glue and water.  Add a couple drops of liquid dishwashing soap to help break the tension.  Then either brush it on, or bab the piece into the liquid then place it.  It is very important that you be patient and wait at least 24 hours for the glue to set.  Otherwise you'll break the bond and the item won't stick very well.

I've also seen (haven't tried it YET) a mound or Aves putty placed as ground cover.  You the press the rubble onto the mound.  The Aves dries hard as a rock, and locks the rubble in place.  Advantage: Lots of time to work with it.  Disadvantage: Once dried, that's it your done forever!

Hey Bomerang,

 You could try lightly gluing it in tiny places or pile it up and over spray it with a spray glue
