After messing around with mortar & grout to make a rock wall I decided to make a mold of an actual rock wall and use polygem epoxy.

Here are the basic steps I have pictured:

1) Started with 35lbs of shot rock from a local quarry
2) Cut a piece of foam backing to glue rock to
3) Placed stones in the desired position & adhered with loc-tite
4) Filled gaps and crevices
5) Applied 8 layers of Envirmold Latex
6) Set mold in base of great stuff covered with plastic wrap
7) Sprayed mold with Pam as release agent
8) Painted inside of mold
9) Applied epoxy
10) Peeled mold off of hardened object

I’m okay with it as a first attempt, but after talking with Polygem I have some bugs to work out; will make another one with the same mold over the holidays.

Let's see if I understand ... You filled the holes with crevices? What is it?
This Envirmold Latex is difficult to get hold of? Why so many layers?
This realese agant where you spray it? on that side which lies against the plastic? Is it not enough with just the plastic?:confused::confused:

sorry for so many questions..

really like what you have done...I would like to try it..

Sorry the name is enviromold, here’s a link Environmolds - Alginate, Latex and Mold Making Supplies - EnvironMolds
A mold requires 4 -10 coats depending on the type of mold; in between the layers you add a layer of gauze. The pam is sprayed on the inside of the actual mold prior to applying the epoxy. The plastic wrap is to keep the mold from sticking to the great stuff which is used to hold the mold so you can push against it to put the epoxy in.
