I wanted to share with you what is going on with the effort to make a base for my diorama
Wanting to have an area of cement slabs I have tried using both wallboard (sheet rock) and foam board
Both exhibit the possibility of being able to be used. The wallboard starts out with a color that is very close to what I want but it is heavy
The foamborad does come in a gray but it is too dark, but, it is very light
Now the thing that works for both is making the dividing line between slabs. I took my hobby knife with a number 11 blade and using the back side of it I scribed lines in both materials. A fair degree of pressure is required as you will want to have a semi-rough line which will look like weathered cement at the joints. Then you take a very fine tip felt marker and go over your etchings. You will find that there will be rough spots which when blackened will become the tar expansion joint material and will look like the real thing you might see
I did this without painting the material so that would have to be done prior to using the felt tip marker.
Now I have to find a paint and a weathering method to give me the final result I am looking for
After readiing this if anyone has an input regarding the painting and weathering please jump right in
