Much better quality and strength, and quicker setting time too! If you were casting a plaster wedging table, the thing to do would be to cast in a piece of expanded metal. Used mostly for lath and plaster, I think, it's like chicken wire or hardware cloth, but more metal, less space. Be like rebar in concrete on steroids. My wedging table is still solid after 25 years and maybe 2" thick. Well supported also. Link to comment Share on other sites More sharing options...
