Creating Real looking concrete

try durham's water putty. it comes as a powder u just add a ratio of water and powder and u got a really good putty.....its cheap, and comes very handy for anything ( it sticks to wood best) i use it as a putty for filling gaps by mixing it with white glue.....it makes it stronger. when it dries u can make it look like concrete easily...
good luck! -DJ

Here is the way I make concrete slab.I mainly use this tech. on aircraft tarmac.I first start out with a peice of thin foam-board from wal-mart,this is posterboard size with thin cardboard over foam.The easy way to remove the card is to soak the foamboard in a hot bath tub and carfully peel the cardboard from foam.you may have to repeat to have perfect surfaced foam.I then scribe in the joints in foam slab.I use a thick acrl.black for tar between joints,remember in hot temps tar will be slightly raised and flush or slightly recessed in cold climates.The way I weather the slab is lightly airbrush slab with thinner to give illusion of pitted or worn concrete in selected spots and use light touch.I weather the slab with shades of greys and tan,use low-tack mask for lines,numbers,etc.,once completed glue to pre-stained/finished wood base.I also discoverd that the foam acts as a natural shock-absorber for air-craft landing gear.

Cool thanks

The celluclay works great. Also Plaster-of-Paris works good as well. If you mix it up thick then spread it out. Before it drys completely rough it up with sand paper or just press the paper on it. After painting give it the old dark wash of dark grey, brown, or black to bring out the texture.

That sounds like a great way to do it

This is how I do it:
I cover a plastic sheet with celluclay or similar, then I press it with sandpaper to get the texture, and it is ready to paint and weather.

After scraping off the glue i put down some scotch tape but the edges are not flat as i want them. Will testors tube glue do the trick ??

Hi,

For making scenery etc. you will find that a visit to a Model Railway store is well worth the effort. Recently I have been using a product from a company called Woodland Scenics, referred to as Fine Gravel, for the Concrete. When Scattered over PVA it sticks really well, to give a more realistic compact look I then use a wall paper roller to really compact it. For the Tarmac/Blacktop Hornby make a specific product for this, I use the same method as above, I have been very happy with the results I have achieved.
I have also used a DIY product for the Concrete, like a wall filler, again I was pleased with the result but found it was prone to cracking when drying out.
