I've a Bernito oven, the floor is faulty, the thin grey covering on the floor has broken away, I'm unable to get the company I purchased it from to come and repair it. Basically I'm stuffed and unable to use the oven at the moment, apparently it was a faulty batch of the covering. Does anyone know what the material is ?, where can I get some more from or what could I use to repair it with?. For the moment I've placed quarry tiles on the floor, these cracked on the first firing. I really love this oven, but am at a loss as to what to do now. Help !!!  |

Hi gb, Sorry to hear about your floor. I would recommend using firebricks on top of bad floor. Would probably have to be thin (25mm) due to lightweight /portable design. Make template of oven internal and use to cut firebricks to required shape. Lay bricks tightly on 50/50 mix of fireclay/ sand (building or silica) and level. Use same mix to "grout" where floor meets oven walls. Have used this method before and worked out perfect. Best of luck

Hi GB,
I might be able to offer you some advice and some first hand experience. I too have had the same problems with my Bernito Oven and had a gruelling ordeal trying to get it resolved. I am currently on my 3rd replacement all with the same flooring problem as you. I have since cut all ties with Bernard and am trying to best advice anyone that needs it.
The material that Bernard uses on the oven floors is Silicon Carbide. It is pretty hard to get hold of...so what i'm doing is covering mine with refractory floor tiles.
How many times have you used your oven?

Hello GB
Sorry to hear about your.....and skyfire's problems with your modular oven. All I can suggest is to re-contact your oven supplier. If you have carried out his first-firing instructions correctly,he should honour his guarentee.
If you go down the route of repairing it yourself, then I agree with woodfiregourmet. The only person I know who sells 1" fire-bricks is Liam from Kilnlinings. Although he sponsers us, this is not meant to be a plug for him. If you live within travelling distance of Sheffield it's not so bad (I think they're about £1.20 each?).
Just another thought.....(I don't know a lot about modular ovens).....The base of any oven should be sat on a solid base with no movement....preferably watertight and insolated (I lay my fire-bricks hearths on thermolite blocks with the same mix as mentioned above........just a thought. Wish I could help more.
Terry

Hi and thanks for the info. The ovens been fired once, it more or less broke up straight away. I have one other oven, that's been great, no issues at all, that is why I bought a bigger one. Silicon Carbide, will make some calls tomorrow and let you know how I get on, did you find a supplier ? Hi GB, I might be able to offer you some advice and some first hand experience.

Thanks for the input, I followed his instructions to the letter, I'm beginning to wonder if he's closed up shop, my phone calls go unanswered. 1" bricks are far too thick, the floor needs covering with thin tiles or hopefully more of this silicon carbide (apparently this was a bad batch or new type that didn't work correctly). Will do some research tomorrow and let everyone know how I get on. Hello GB Sorry to hear about your.....and skyfire's problems with your modular oven.

Hi, thanks for the advice. Where would I get hold of 25mm firebricks ?, where would I get hold of fireclay ?. Hi gb, Sorry to hear about your floor.

why don't you break out the floor and sit it on a bed of firebricks thus maintaining the origional height and all important dome to door ratio. You can get storage heater bricks at a good price on ebay. nice and big

The oven has to be portable, I put it into the back of my van, move from place to place with it. why don't you break out the floor and sit it on a bed of firebricks thus maintaining the origional height and all important dome to door ratio.

GB wrote......."1" fire-bricks are far too thick....where do I get hold of 25mm fire-bricks" .....they're both the same thing.
Fire-clay(powder) can also be bought from Liam, but many pottery suppliers and selective building merchants also sell it.
Not a bad idea from Slowfood....the normal 3" fire-bricks are only £1.30 (ish).

DUH !!!, yes, sorry, I'm brain dead.!!! I meant where can I get hold of thin tiles/bricks that would be suitable. 1 inch is far too thick. The floor is fibreboard and is fibreglassed in place, I don't want to cut this out and try and replace it, the oven is very portable and I need it to remain so, the frame it sits in was designed specifically for the width/height for it, I'd have to alter that as well if the dimensions of the oven changed.

It's difficult trying to envisage your problem exactly. I don't mean your disappointment in your supplier... this is clear for all to see but the actual problem ... "floor is fibreboard and fibre glassed in place" ...is throwing me off a little. I am no expert, but if I could, I would love to advise.....any chance of uploading a picture.
This is only my opinion but without seeing a picture, I think anything under 1"/25mm will fail. If the floor has already cracked then ....there must be a reason why. If you were in my area I would willingly have a look and advise......anywhere near S.Wales?

would castable refractory cement make a suitable floor? If so you could do a thin skim layer.
also what about kiln shelves? You can get these thinner, use them as floor tiles?

Hi, Please have a look at the image I've attached. The red line indicates the outer shell of the oven, this is fibreglass. ---------- The blue line indicates a fibre board of some type, it's 6mm thick. The board is not vermiculite based from what I can tell, it appears to be some sort of fibre. Similar to this kilnlinings.co.uk/ceramic-fibre-boards/cf-board-1400gd , it is probably not the same, just similar, but until I handled a sample of the kilnlinings material in my hand I couldn't say for sure. ----- The yellow arrow points to a thin layer of what I believe is Silicon Carbide, this is maybe 0.5 to 1mm thick, it is this material I need to source. My best guess is that this was either troweled or sprayed on after the board was fitted to the shell. My friend has an oven as well, his doesn't have the same problems, his floor is fine. I'm seriously considering trying to remove the floor to see what it is constructed of in order to effect a repair, but of course would just like to find a way to spray or trowel on Silicion Carbide. gb It's difficult trying to envisage your problem exactly.
