I planned on 2 layers of FB blanket over my completed dome, followed by a perlite-Portland layer about 1.5” thick to lay my external shell decorative bricks into.
A] Is there any reason I couldn’t just use a chicken wire mesh over the blankets to cover with the insulation mortar layer? I’ve read in this forum 1/4” screen before stucco… but for thicker perlite-Portland mortar would that be needed? Chicken wire would be easier to work with IMHO
B] Anyone anticipate a problem setting my standard bricks into the wet perlite-Portland layer? (I would mortar the brick joints with standard mortar, or the fire clay mix if that’s recommended) When I built my oven floor I used my insulation perlite layer to tamp fire bricks level using paper towels beneath to prevent adhesion. Worked great.
For the outter dome I’d actually want the adhesion of the insulation layer. Am I missing anything?
