I will be doing a dio that will 15"x32", it will be a German repairshop. There will be an area w/railroad tracks coming in, but 3/4 or so of the are will need to be "concrete". I have used plaster as well as drywall mud before as concrete, just not sure if that'll work on this large of an area. I have also used a model railroad product, that was like fine sand they labeled as concrete, but I played hell getting it to adhere. As always, thx for the help. (forgive the picture)
Fine grit wet / dry sand paper is the right texture and almost the right color. Cracks, expansion gaps and other details will need to be added but a 8x10" area can be covered fast & cheap. Trying to simulate the large area with plaster or the such will be more work and possibly less than satisfactory results.
For poured concrete in wooden forms I always thought strips of fine grain wood would work as the concrete keeps the wood grain after the forms are stripped off. Just the gaps will need putty or gap filler to simulate seepage of the wet concrete through the wood form.
I have read of one modeler in FSM who carved a rock / brick / concrete structure out of drywall plaster. Remove the backing paper completely to expose the plaster material in the middle. The beauty of this technique is its easy to carve and battle damage after can be added easy & realistically.

That's exactly what I'm afraid of. I like the sheetrock idea, it reminds of how us remodellers do a "California patch" w/drywall, when there's no backing.....any small pores could easily be filled. Thanks.
Seams in the concrete can be simulated by cutting the sand paper where you need a seam. It doesn't get easier than that! Light gray automotive primer sprayed on the sand paper would be a good base coat color. A light wash or Panzer gray followed with a light dry brush of lighter gray and you will have excellent concrete. Don't forget oil stains, scuff marks & chips from heavy tracked vehicles and other details to make the surface come to life.
love it !! thx so much...I'm guessing you've been down this path ??? what grit paper ? 600?
Ditto on the sandpaper, works great! I can't remember what grit I used, it was pretty fine though. Came in dark grey. I sprayed some primer on it randomly. For oil drips and stains, I used thinned black(very thin!), contact cement for fixing it to the base.
This is a 32nd scale A-10,....BIG area to cover!!!
Sometimes I'll add a few "weeds"(craft moss) coming through the expansion joints.
Any 'wet' paper starts around 800 grit. Depending on scale 800 should work for 1/35, smaller scales will require a finer grit as the texture gets smaller & finer.
Actually I have never used sand paper in this way. I tend to think 'scratch build it' a lot as any decent hobby shop is a hours drive away and I do not get into the city much. fermis is a well known modeler here and his example looks great as usual.
