I sat down last night and mixed my very first batch of sculptamold. The mix itself had large lumps in it (about 1/4"x1/8" for the very largest) that were composed of not setup plaster but what looked like shredded cardboard. Thinking this was by design I proceeded to add the water to the mixture and mix it, but the lumps had to be ground up against the side of the mixing container with a spatula in order to let the water seep into them. In the end (I had lined the bowel with a plastic bag) I had to lift out the plastic bag and kneed it with my hands to work out most of the lumps. Then I had to apply the sculptamold by hand in order to smooth it and squish the remaining lumps. I know that this stuff is not meant to act like plaster, but is it supposed to have lumps in it? I was afraid that if they stayed in the mix that when the terrain dried the lumps would weaken and cause the terrain to easily chip away, or crack.
Finally, the question: Does this sound correct for this stuff, or do I have an old or bad batch of sculptamold? If I had left the lumps alone would they absorb enough moisture from the sorounding mix to set the plaster?
Thanks,
