I'm not sure where to post this or if this is something I should even post on a smoke forum.....it's more of a construction question. I am working on my cold smoker base.....the base is made of concrete blocks. I am using the dry stack method.......(use rebar, stack dry and fill some of the holes with concrete.....) I would like to finish the outside of the blocks...probably with stucco. Here is my question, do I layer/paint something onto the blocks, some sort of sealer first...or do I go ahead and stucco right onto the blocks? Any help or advice would be welcome. Thank you! This is a dry run picture of the base to give you an idea of the size.... These pictures are not current, I have started on my smoke box and pipe to the base. The black hole in the base is where the smoke is piped in.
