Traditional stucco starts at the mesh layer to which the scratch coat is applied. Some feel that applying mesh to a dome is too hard to do. For those, the newer stucco mixes have fibers included in the mix. Yes, reinforced concrete, mortar, or stucco will get season cracks for which a flexible finish coat can accommodate. Mesh and/or fibers are considered reinforcement. No reinforcement = gaping cracks. A flexible coat can't accommodate for that. Do one, the other, or build a roof over the oven. just sayin' .Last edited by Gulf; 08-22-2017, 05:49 PM.

From what I've found, any cement is going to crack over time and if the oven it not under a shelter it's going to start leaking if there is not a special skim coat applied over it that will not crack. The ones we checked on for that was fairly expensive, one being rubber based and considered the best but very expensive since it's not sold in small amounts needed for an oven. The supply house specializing in stucco finishes recommend a synthetic stucco, it will not crack. However, it's a soft outer layer and will puncture if hit very hard with something and poked.
Since at the present time, I have no plans to cover mine, I'm going with the synthetic stucco outer layer.
I can also verify what SS said about inconsistent coloring. My limited skills could NOT produce consistent color batch to batch, hence a blotchy appearance. The Parex product has a wide color pallete and is fairly easy to apply. I used about half of this bucket to cover my oven and, I believe, it cost about $80 at Continental Stucco Supply.

Good clarifying question Russell. I couldn't imagine someone using regular paint to color the stucco, so I assumed the person Shawn was hiring knew what he was doing...but you are absolutely correct--never assume
Shawn, please let us know if he just said "paint" because it was easier to say than liquid colorant or coloring additive

Has anyone heard of this? He sounded like he knew what he was talking about but I had to check here.
In addition to synthetic stucco as Ben mentioned, there are also additives you can buy for concrete or stucco that provide pretty good waterproofing. Look up Xypex or Kystol additives through the Internet (concrete waterproofing additive). Also as Ben's future son-in-law infers there is no perfect, one-time way to waterproof an oven other that put it under a roof. The old saying is that there are only two kinds of concrete...one that has cracked and the other that will crack. By the way, also look up synthetic stucco on the Internet...some interesting issues.
Post some pictures of the stucco job during the process and when it's completed.
