After mixing up a batch of parts A & B of the clay I apply a thin veneer of it to the cavern ceiling working it down onto the walls of the cave.
I can't work too large of an area at a time because I have to impart a rocky texture to the clay before it begins to set up.
This photo is of the entrance to the cavern. It is made of hardware cloth and styrofoam board.
After adding a layer of mache I covered it in Apoxie Sculpt clay. I find the mache closes the pores of the styrofoam board otherwise I keep getting loose particles of styrofoam as I apply the Apoxie.
An added benefit is it bulks up the piece without the added weight ( and expense ) of a thick layer of Apoxie clay.
This photo shows the finished cave entrance painted with acrylics and placed in its position on the plywood base. I now begin building up the rest of the cliff face which will eventually be joined to the entrance.
Here is one of the supports for the interior of the cave. It shows the wood frame, styrofoam board and veneer of Apoxie Sculpt.
This is a close up photo of the rock texture of one of the supports.
I hope to get a great deal of work done today before the heat and humidity return later in the week!
