By weathered , there are several ways one can depict older concrete. You can have grease stains , pools of oil , cracks , gravel showing , I dunno Chris , you need to give me an idea as to what effect you're trying to achieve .

That's fairly easy.

1. If you want the block look, score the board first to simulate the sections of floor.

2. Paint the board with water-based flat gray paint. Oil-based paints may damage the foam-core.

3. Using dry-brushing, brush on varying shades of gray, black , brown/rust and other colors. The idea is to slightly discolor the board, not completely coat it.

watered down brown/black acrylic paints make good oil stains.....whatch what you use since some stuff will burn foam, try on scrap peices if you aren't sure

O K , to do grease stains , generally, I'll use a combination of both a Semi Gloss acrylic Black and Flat black . The best looking color to me that represents concrete is from Michaels art stores . Go to the water based paints and get the El Cheap-o Color Smart brand . They have a color called Suede . You'll have to put a few coats as this paint isn't very opaque . Still, you can achieve some really good results out of this paint . To do some cracks in a piece of Foam core , take a pencil and literally draw jagged lines using a VERY DULL POINT . Then coat the board with the suede paint , swab some Burn't Umber , ( A Dark Brown ) into the cracks and wipe up the excess as fast as ya can .

I included some old dioramas I've done over the years all depicting different gas stations . Maybe one of the shots will help explain ............

thanks for all the help guys... here is my first sample its on cardboard and i put some plaster over top the cardboard. then i mixed a tan and a gray acrylic paint and got a good concrete color. i didn't allow the plaster to dry long enough so the lines are a little sloppy but im going to do some more samples to see what i like best. once again thanks for all the advise let me no what you think of the first concrete sample.
