Hey
studdlygoof, did you form the Great Stuff to the shape you want, wait for it to dry and then apply the tan grout on top of the dried Great Stuff?
Could you also MIX the tan coloring into the Great Stuff, so that you can have the tan color Great Stuff????
Am I making any sense?? I am just wondering if I could just mix colored sand or that tan coloring directly into the Great Stuff, as to eliminate one step.......
Your set up is looking great
