Re: Waterproofing Dome
Gulf,
I like your particular vent.
Its not tropical here but I think it has its merits (particularly as weather in all parts of the world are becoming more unpredictable) and it could easily be capped off and painted over if not needed anyway.

Re: Waterproofing Dome
V-Wiz,
I like the way David treated the vent issue. It has been done several other ways. Neil2 used a decorative plate as rain cover for the vent hole. CobblerDave used a brass insert with a removable plug. I am incorporating a filter/breather cap used for industrial gear boxes. I will have to decorate mine in some way to allow it to blend in. UtahBeehiver is on the road to installing a vent as well. There is no telling what Russell will come up with to decorate his .
Here is what mine looks like at the moment.
The vent that I have is a 1" threaded vent with a 4" X 3" filter cap. They can be found in smaller sizes. I am pretty sure that the one I looked at the other day is a 1/2" threaded vent with 2" X 1 and 1/2" filter cap.
This one is placed in a 2" to 1" threaded bushing. I will not permanently attach it until I apply the split brick to the dome.
I think that a vent can be installed in a way that it can be removed and plugged inconspicuously. It can be left in place until the end of the curing process. I'll probably leave mine in place though. Our wet season is year round .

Re: Waterproofing Dome
Can someone post a pic of this vent in question. Almost seems like its not even worth waterproofing(in my case)

Re: Waterproofing Dome
There are two schools of thought on waterproofing the dome because stopping water entering can also trap it in. We live in the tropics and can have a few months of torrential rain. Consequently I've opted to waterproof, but incorporated a vent that surrounds my flue. The vent can communicate with the insulation layer and help to remove moisture and also relieve steam pressure build up. Remember that when the dome is heated from the inside any water trapped in the oven will move away from the heat source i.e. outwards.

Originally posted by Gulf View PostIf you seal or waterproof to the extent that it can't breathe, I feel that a permanent vent is necessary. Granted, the interior of an oven is not sealed and will be an escape route for moisture with several firings. But, I think that a vent at the apex is good insurance for present and/or future moisture issues. IMO the vent can be a a removable plug, gooseneck, or a covered vent. It can just be one more avenue for steam to escape
Just Sayin.

Originally posted by V-wiz View PostAre you saying to have a permanent vent or a temporary vent till the stucco dries?
We all know that stucco is not water proof, so i was thinking of adding/painting the stucco after the stucco is dry. Keep in mind i wont have Vcrete just insulation rolls.

Originally posted by david s View PostI don't really agree with you because one of the problems with creating a waterproof skin is that it is not permeable. Acrylic coatings do not breathe like a lime coating can and they run into problems if there is significant moisture behind them just like acrylic paint on a wall ie. blistering. That is why it is essential to dry the oven out thoroughly before applying it (say 10 decent cooking fires). Any subsequent moisture build up can then be dealt with by a vent.

Originally posted by V-wiz View PostWhat David said, also if waterproofing is being added later i dont think a vent is needed as stucco itself does breath. So if elastomeric is being applied later down the line a vent wont be needed
