New pre-cut kit build in Adelaide

Building with a precut kit... I can see the advantages of not having to worry about the arch transition etc etc. It's certainly coming ahead quite well.
Are you still aiming for the "oven pic " you posted earlier with the oven hearth height the same as the surrounding base. That look is certainly smart and clean.
Love your work

Re: New pre-cut kit build in Adelaide

No reinforcement used but appears OK, see above quotes, it may allow some movement of floor tiles?

I had made that comment thinking your castable was the finished floor. Concern about the castable is all moot, since you covered it with floor tile...I don't know how I missed that.

Re: New pre-cut kit build in Adelaide

If your castable is level and tiles fit well you should be good, no mortar, tiles need to float since they will expand and contract. If tiles need leveling, use a 50/50 mix of sand and fire clay installed with a 1/4" or 3/8" or so notched tile trowel right on your castable base. Nice looking kit.

Hi Liteceeper

Ditto with Russell

Thanks for advise Russell & Colin but I have stuck to Ben's plans and used a mortar mix to set floor as the castable had a dip on LHS throwing tiles out of whack.

2 refactory mortar
2 sand
1 lime
1 GP cement

I guess the bricks and floor will take up their own positions once the oven gets fired up.

Don't go too far ahead with dry fitiing, you'll find that things change once you start mortaring the brick.

Looks nice so far, and I'll be interested to see how that castable skim coat holds up. Did you add reinforcement to it?

Had a good weekend finally building oven, Friday afternoon laid floor, Saturday morning ground edges of floor tiles to remove slight raised edges on a few tiles, then laid first 3 courses.
Today (Sunday) I filled wedge spaces between bricks with castable, thought best do this whilst bricks are still wet from laying them. Then laid fourth course.

Re: New pre-cut kit build in Adelaide

More update - sorted precut bricks and did a dry fit to check if I know what I'm doing.
Ignore floor tiles not central to calsil outline I mucked up my centres

Pays to do a dry fit first I guess.

What,s the consensus do I mortar down floor tiles or bed in sand?

Re: New pre-cut kit build in Adelaide

Time for a update, started on oven build now I have completed render (stucco) of patio in area of WFO. Cut calcium silicate board to size and laid straight on top of hearth slab. Covered with aluminium foil to prevent moisture being drawn out of heat bank too fast whilst curing.
Next made form work for refactory castable heat bank 25mm thick, mixed, poured and let cure for three days.

Re: New pre-cut kit build in Adelaide

Yes I know what you mean, xmas is just around the corner and I promised SWMBO the oven would be up and running.

Re: New pre-cut kit build in Adelaide

Thx liteceeper

Partners son is a plasterer and has rendered will get him to do one wall and show me. Will take it from there but need to do that soon.


So I can finish the oven.

Re: New pre-cut kit build in Adelaide

Nice looking base, looking forward to seeing your oven work. I would recommend installing some CaSi or V or Pcrete under the oven floor. Now's the time to do it.

Thanks UtahBeehiver for compliment, yes I have 50mm (2") of CaSi for base insulation.

Hi

Is this your first rendering effort. If so how did you find it?

I stupidly built the oven before rendering behind it now making task that little bit more diffcult. Think i might have to render before completing the oven insulation while i still have 200mm of space available.

Hi Colin, yes first time render, had advice from brother whom has rendered whole house. Biggest hurdle was trying to float with polystyrene float to early after applying render with steel float in fear of the render going off to quick.

I'm using ABC Drypak Render which is very forgiving, but you must follow the render / water ratio to exact proportions, although when you first mix it seems way to dry. Use a large paddle paint mixer in electric drill.

Render comes in 20kg bags, so I mix 2 x 10kg lots and find once I finish second application of render with steel float, the first section is about ready to float with polystyrene float. Once finished I final float with foam float.

I have a little pump pressure garden sprayer with water which I use to give a very light misting if the render is dry in sections.

Long weekend this weekend so hoping to finish render and start oven build yeah!

Hi Colin


I have started rendering patio walls whilst letting hearth cure. I figure easier than once oven is built.

Re: New pre-cut kit build in Adelaide

Another arch at the back would have maintained same strength. Anyhow too late.


Is your hearth height figure 1150 after the deck is built or now?

As for your question of hearth end height I'm thinking at 6'4" you might be too low causing you too stoop working the oven. From floor to hearth height I believe recommendation on this site is to have it at Elbow height. I'm 6' and have my hearth height is 1220mm.

If it is a compromise between your height and SWMBO height then leave it as it is.
I had my deck completed and cut the deck out my oven base is cantilevered over the deck.

Hi Colin
Height will be 1150 after deck built, but I can add another layer of calsil board (insulate, insulate seems to be the theme).
SWMBO has declared WFO as extention of BBQing therefore my domain

Re: New pre-cut kit build in Adelaide

Fun times ahead Plastic & formwork comes off Saturday.

I did under estimate the size of the stand, its big, you are correct an entrance at the back would allow easy stacking of wood etc. but my idea was to build as bullet proof a stand as possible. Could use it as a storm shelter or air raid shelter

Slightly of topic, the height should reduce as a timber deck is to go over foundation slab, my design height is 1150mm to cooking floor, I'm 6' 4" so hopefully workable. Any thoughts?
