That's very informal...thanks for sharing.

Very nice. Gave me an idea to make molds for the concrete to make actual frag plugs, not just discs.

^ care to share Markitet?

 

[markitekt]

^ Yes, after I don't fail.

It would probably include a mold out of something like latex, to which the concrete wouldn't bond easily. I'll look up some sculpture techniques and maybe come across some ideas.

make a trough of wet sand and then use a frag plug to make holes in it. pour in the mix in a thinner consistency. basically sand-casting them.

That's how I make my reef rock. Making a frag rock tonight probably. I'll be using cut up garbage bags to cover actual plugs that will go in the top and cure overnight before putting into water. I've made 6 solid pieces now. Two good size rocks, a cluster I made into INCREDIBLY porous rubble, and a more flat sheet that is my first attempt to make "wall rock."
