Concrete Slabs

rjwood_uk · 09-09-2006

i made this by cutting a scrap of wood to size. for the slabs i got some cheap sheets of assorted sandpaper, looked through them and chose what corse to use. i settled with G2 but obviously this will change from scale and personal prefference.

I sprayed it white, waited for it to dry over night then sprayed over it with nutural grey. Again obviously this would depend on what you want the concrete to look like.

I then cut them down into 80x120mm sections (again obviously this would vary for different scales and personal prefference)

I have stuck them down with sticky back tape for now but they easily peal off with no damage. Dont use spray glue as it is not strong enough.

You will find the sand paper (being paper and all) may curl up after painting. Make sure you blue tack it down during the spraying stange. Then once all dry just stick it under a weighty book for a day or too to flatten it out!

let me know what you think. all comments, good or bad will be greatly appreciated!

I think it looks pretty convincing Richard.

Just remember do not align the joints with the frame you put it in. Have it at an angle with one corner made of grass as the edge of the hard to give a far more interesting effect.

Escellent finish there Richard! As hsa been said in a real diorama setting remember to stagger the joints and also a cracked corner would not go amiss.

cheers

As another aide to this icelolly sticks make for great american carrier decks and if you want the cracks in your concrete to look real crease or crunole the paper to create them then fill in the creases with ink

I actually have an article on this in an American mag in my cabin and the guy used mounting board from a picture framers.

He scored it with the back of a knife and then shaded the slabs with his airbrush dusted over a right angle peice of thin card, laid on the scored edges. Finall a bit of a wash in the creases, a bit of crack detail painted in and it looks amazing and very simple to do.

Any more tips when it comes to creating a realistic looking concrete surface?

Really battered old concrete items you see at the coast and on old military fortifications have a real character of their own after the years of neglect have taken their hold and weathered the concrete.

When it comes to making military vehicles look battered, theres lots of tips ranging from using marmite as a masking fluid for chipped paint, graphite powder for burnished iron parts, drybrushing silver on worn edges and a whole host of washes for making it look greasy, oily, dirty, plus the weathering powders for, dirt, dust, mud, and more rust...

Any good products for making that old scratchbuilt military bunker model look like it's been there for the last 60 years or so?

There's the obvioud sand, to build up a corroded surface, washes, drybrushing etc...what else? What other household products can we scrub, flick, or splatter?
