Advice on Stucco please

[kallipigous]

How long did you wait between coats? Did you keep it moist?

Ah well my chimney is going to be stuccoed up the pipe sadly. I have something similar at the base but my wife want's the stucco shell to go someway up the pipe.

I found a 6" flange that duravent sell so I'll try that and use some silicon.

Have you thought about throwing some mesh around the vent pipe and taking the stucco all the way up to the storm collar that is built into your flu cap?

Just some homebrew mortar.

I've got the exact application and am using metalbestos chimney and have that exact flange. That's a great solution. When you say "grout," do you mean real grout? Probably a dumb question. Anyway, this will lead to an improved chimney for my build.

K,

I am not sure if this will help, but here are some pics of Metabestos flange similar to the Duravent flange you talked about. The flange was connected to the brick with concrete expansion bolts with a beads of high temp caulk under the plate, then capped with another layer of fire brick. Once the SS chimney was screwed on the flange I grouted the gap between the brick and chimney. It is going on 3-4 years no with no issues of the grout cracking. The double wall chimney keeps the temperature in the outer skin in check. Note the middle pic is looking at the bottom side.

Any advice on sealing the duravent chimney stucco join?

That's above my pay grade, but I've seen some fab a ss flange, directly above that joint, to shed water. I think that David S. has done this on several of his builds.

Hi
I used a flat trowel to apply the stucco, The thing I learned was to make sure you have enough material for your first coat, you have some time to work the material, the dome shape is not that difficult. after the first coat I still had some areas that the lath was at the surface but with the second coat you have a firm base to build on. just try and keep the thickness of your second coat consistant. your final coat will be even easier
Hope that helps

ok great so I'll concentrate on the wire and not worry about filling underneath and if I get air gaps then that's all the better.

From that pic, I don't see a problem. You will be just fine .

Ok thanks. I guess if I double the chicken wire it will give me smaller holes and make a stronger mesh to bind to? I am slowly filling in the holes as best I can but where the insulation overlaps it is thicker and there are creases. It's just impossible to make the insulation perfectly flat. I'm trying to avoid pinning the wire to the insulation as that shortcuts the insulation. If there are occasional holes underneath the wire and stucco I guess that's just extra insulation?

If there are "air spaces" underneath the wire, that is insulation too .

Here's an example. Small creases under the wire.
