I started on the p-crete insulation layer over the ins-blanket. Mixed 60/40 perlite/vermiculite to 8-10:1 cement and threw in a few handfuls of clay powder. Drymixed and added water and it was pretty workable.
I'm running into an issue though. My oven stand isn't 100% true and plumb. DIY limits on my skills I guess.
On one side of the dome I am about 1" from the edge, which is okay for rendering. But on the other edge I am only 1/2" from the edge.
I wanted to render, and then make a brick split veneer like Gulf and others have done. But given my space limitation, I won't have space at least at that narrow ledge to do a full 3-coat stucco.
If I cast a small cantilever to increase edge space, probably it wouldn't hold up.
I wonder if I can just make a lime rich render of cement, lime, sand, and trowel it on. Mostly in about 1" thickness, except at the narrow spot. I've got alkali resistant nylon fibers that I'd throw into the mix and then wet sponge to create a smooth surface. I also have a fat based liquid that I found in the home's store here, it is supposed to be mixed with concrete to create water resistance. I would add that to the render mix with the nylon fibers. And then once dry/cured I would consdier to paint it with a wather resistant acrylic (colorless) to max out water resistance, before plastering a brick veneer.
Anyway, long text here, but just sharing in case anyone has any do's and don'ts for such rendering solution. I'd also consider like DavidS recommendations to keep the render moist - maybe even with cling wrap. But my doubt is - if I cling wrap the fresh render isn't the wrap itself going to create indentations and 'maps' in the render? At least that's been my experience when covering wet concrete with plastic - it destroys the finish...
One important question also: I have a tuna jaw and some fatty pork marinating. I want to put some coals into the oven today and grill these items. Is it okay to cure the oven with half shell of v-crete drying on the outside?
