hi everyone back with more as promised,
this is where i am with the diorama base:
to start i made my rubble the same way as for my Jagdpanther dio, mixing plaster with acrylic paints from a tube to make three different colours: one light gray, one light gray/brown and one dark gray.
above you can see the large pieces i glued down first using white glue undiluted.
i then started working my way around the whole base first laying down white glue using a Q-Tip which i cut one fuzzy end off and then placing rubble on one small area at a time.
i just slowly go from a lower area and work my way up so the new rubble has something to keep it from rolling downhill and out of place.
this process can take time. to lay all the rubble out with debris took 5 hours as i build it up and add "gravel" from the railroad section of the LHS to fill in nooks and crannies.
as i got further along it was time to crackle. first i brushed on Vallejo Crackle Medium with a brush quite generously on the top surfaces of the large pieces. i let this dry for 5 minutes. brush in one direction for all the pieces as this plays a role in how it crackles.
next i brushed on Vallejo white acrylic with a wet flat brush, again brushing in one general direction on all the pieces. i feathered the edges for this particular project to make it look like a rough treatment.
above is a closeup of the crackle finish once dried. this will be emphasized even further once washes are applied.
next step is to spray diluted white glue over the rubble to hold down all the material in place as only the bottom layer has made contact with the original white glue smeared on. before doing this is the prime time to test one last time how your model(s) sit on the surface for good contact.
after it dries i will start the painting of the base, washes first, then highlights and then pigments to finish. this should add more scale to the rubble and unify the base.
then i will begin the pool/water portion of the project... fingers crossed as this is my first attempt.
cheers and happy modeling to on and all, bd.
