What a great find stumbling across this forum!
I have just bought a van with brick pizza oven installed. I'm hoping someone can offer some advise, as I noticed some damage to the roof. It looks like it's missing a brick or two as well. Can it be repaired, and if so,how do I go about it?

Hello and welcome; the damage you refer to is undoubtedly cracking and there are very few WFO’s without cracks. The missing bricks are more of a concern but some photographs might assist in any advice.
Am I right in thinking you intend to use the van/oven to produce pizza commercially ?

What a great find stumbling across this forum! I have just bought a van with brick pizza oven installed. I'm hoping someone can offer some advise, as I noticed some damage to the roof. It looks like it's missing a brick or two as well. Can it be repaired, and if so,how do I go about it? Wood fired ovens are heavy and brittle. Consequently they don't stand up well to being transported. Brick ovens in particular are even more susceptible to road vibration. Cast ovens fare far better and some manufacturers offer a one piece casting specifically for mobile operators as they fare a bit better than the multi piece castings in regards to vibration. They are however more inclined to create their own expansion crack usually a vertical one directly opposite the door. Short of a total rebuild I'm not sure that it would be easy or successful to repair. If you want to give it a go, get some dense castable refractory and try wetting the area to be repaired fill the area and keep it wet for 24 hrs by propping some wet rags against the filled area for 24 hrs. Calcium aluminate cement, the active ingredient in castable refractory cures in 24 hrs unlike calcium silicate cement which takes way longer. The area then needs to dry for at least a week before firing. Avoid direct flame impingement to the area and dry it really slowly or you'll get steam spalling. The previous owner was probably given similar advice and therefore decided to sell. Also avoid at all costs any unmade road. There have been reports of mobile brick ovens rattling to bits on several occasions. |

Not the best news then! Could I replace some of the missing blocks with vermiculite blocks cut to size and fire cement? Guess I don't have much to loose 😞. How do I upload pictures

In the 'Quick Reply' box you should see a click box that says Add image to post; just go from there.
