Hello, I have finished my Cortille Barrile and used S-Mortar as the exterior stucco coats with fiberglass hairs to control cracking. 3 full coats with fibers and no micro cracking. I then applied Xypex concentrate as a sealer to the exterior. This is industrial concrete sealer that is used on water holding tanks, etc. We plan to veneer the outside of the oven next year.
One issue I am having is sealing off the doorway from water intrusion from the rain. I noticed the front few inches of the hearth brick are getting wet.
What strategies are other people using ?
