Default Re: new build in Brisbane - Vibrok Caminetti

Thanks for the input guys.

Dave - colours aside, my current design decision is how to finish the dome render along the front.
I see the majority of people here have an oven with large bricks framing the entry.
This allows you to simply render up to the back of the bricks and finish the render there and it looks great (such as Greenman's - Daves is a bit different in that you have bricked the entire oven).
Unfortunately with this oven it already has a large, pattern entry that is one piece with no 'back' for me to finish my render against.
I can either lay a row of bricks all the way around the front edge of the entry so that my render can stop at the back of the bricks, or I can extend the outer edge using the render as shown in that picture I linked.
Lastly I can just taper the render off to the edge of the entrance.

I don't really want to have to lay a row of bricks but the other two options using render I think will be difficult to get a nice neat finish.
I highly doubt I have the skills/ability to get a nice flat edged render finish as shown in that picture, unless I pay a professional (which I would be OK with depending on price).

I hope I am making sense here and you guys understand what I am talking about.

Given the oven shape/style, which of those 3 options would you go with? Or suggest an alternative?

G'day
You could achieve the result shown in you link .... Easy!
The front piece of your oven is flat great. Take a piece of 12 mm ply cut it oversize by the amount of thickness you require. Fit to the front of the oven, centre it up and sandbag in position so it doesn't move. Cut the insulation back from this so the render can fill the front. Render up to the board and because is oversize by the thickness you require you just level to the edge of the board. Perfect thickness and straight edges.
By the way with the oven in your link that might not be render either as the final coat. I helped with pearlite/cement on an oveni and to finish the surface we just tapped the surface with the flat of a trowel. It made it easier to get a smooth lump free surface and left a soft textured finish which was painted only.
Don't use a gloss paint, use a flat paint, it softens the surface a gloss only shows up the imperfections
On the tiles . They aren't wide enough and leave you with a small slither cut the tiles down so you can get the tile gape where it looks best . Cut up a cardboard box into tiles sizes and see what works best. A cheap tile cutter will last long enough for the tiles you need.

Cool Re: new build in Brisbane - Vibrok Caminetti

G'day
Just noticed a new pic at the top of the forum . Nice oven real clean lines . Noticed some cardboard on the tiles then the render was done over that. Pull the cardboard out. Clean tiles and you then have the gape to put a bead of waterproof gape sealer in. How easy is that!! I like that idea.

Yeah that oven does look great and a good idea - might have to do the same

As for my oven and the entry area, that is also what I was thinking on how to do the render around the entrance and so obviously you think this style would look the best for my oven?
I guess then this weekend will be insulation + chicken wire.
Following weekend will be tiling + mortar front bricks
And then it will be dome render.
Give it a few weeks and I can then paint the dome and seal the tiles.

Not really sure what you want your oven to look like .... But your pic was quite a nice oven. My own was a dome with a box stuck on the front, lack of funds slowed me down at first. Smashed my hand and that put a moka on things for a while there too. Brought a short handle axe that I could use one handed and kept cooking though.
One thing that I've thought of is that if the face piece of the oven is not flat enough and that would be a disaster if the cement bleed through. I recon I'd get some blue tack and roll it into a thin strip and run it around the entrance . That should provide a waterproof seal that easy to remove later.
I'd be thinking about curing the oven too. I know it was cured before but its been moved and reconfigured. Recon you could get a light in there to make sure its dry before you put the insulation in place . Once that's in place you could start with charcoal beads and real flame. A read of curing your oven section wouldn't go astray about now.
Regards dave

Good tip on sealing the front, thanks. Seems the previous owner used a silicon sealant around the edges. Could use a clean up and then maybe a coat of paint to bring out that texture.

I spent some time in the cool morning to do my first insulation layer. Pics attached.
I wanted to start with the 50mm blanket and did the dome. I actually used the entire blanket supply to cover the dome!
Really happy I bought that box of 25mm as well as this will give me enough for a 2nd layer on the dome and 2x 25mm layers on the front entry.
Working with the blanket isn't too bad to be honest. Cuts and moulds well enough.
Unfortunately tho its hot as hell in my protective onesie, soaked through after the 30 mins or so I spent shaping/cutting.
This afternoon when I have shade I will do the 25mm layer and tie it down with the wire, then maybe do the chicken mesh tomorrow morning.

That's a great job on the insulation.... Very neat, you must be pleased.
You must post a comment on any differences you found in working with the 50mm and the 25mm insulation. Not many would have experience with both thicknesses. Are you really going to bother with the pearlite/cement layer? 50 mm is standard for ceramic and 100 mm for pearlite/cement. Your over that now by 1/2 again. You could go strait to render coat saving yourself all the drying time with the pearlite/cement which is measured in many weeks till dry enough to render. My own is 50 mm of ceramic and 100 mm of rockwool literally rendered the next day.
That entrance piece, in my opinion looks pretty good unpainted, personally I wouldn't paint it. I would wire brush clean then seal it with a clay pot sealer to stop it taking up moisture. But that really up to you, and what" she who must be obeyed wants"
Have fun with the bird wire, the only thing that I can think off that might be helpfull is if its a bit baggy in spots grab pieces of wire with you pliers and twist sideways. Don't go to fussy and go super tight need it for next layer to key into
Regards dave

Thanks for the compliment.
I am happy enough with it. Could be neater but they all fit well enough - I am happy I had just enough to finish with the 50mm.

Well the pearlite cement layer is my render layer really, as it will painted to waterproof it after and then it's done.
When you say a render only coat - do you mean just cement without the perlite?
Good idea about clay pot sealer too, I will do that and for the entry landing too I think.

Did the second layer with the 25mm. Didn't really find it much different to work with compared to the 50mm to be honest. Less to cut through of course but being lighter it doesn't sit down as heavily too.
I do have a bit of 25mm leftover, a couple metres maybe.

I tied it down with wire and had planned to do the wire mesh but then forgot I hadn't applied the rigidizer - by the time I applied that it was getting dark and late so decided to leave that for the morning.
I actually did all the wire ties after I had laid both layers. The blanket seemed to stay down well enough and it would have been awkward tying and then removing and re-tying etc. I am happy with how it has turned out and have no doubts that it will work fine - though it does not look as neat and tidy as others on this forum.

Also included a photo with the lighting system I setup for the area. 4 lights - one each for the two benches, one for the oven and one for the BBQ

Hi Applor
Good job on your insulation, see PM's a bit late though.
I believe you need to apply a cement render over your perlite render once that is complete as it is fairly coarse.
I intend to use DryPak Render coat (about 5mm thick) over my pearlite insulation and then paint with Dulux Acratex once I finish the surrounding benchtops.
Interested to know what others think?
