How to repair exterior cracks on your wood-fired pizza oven

Heating a wood-fired oven will create small natural cracks and dilatations to appear on the exterior and sometimes in the interior of the oven, particularly on the exterior grout joints and dome. This is a completely normal and natural process due to the thermal dilatation of structures and does not affect the normal functioning of the oven. These natural cracks and dilatations can be seen in many structures such as buildings, bridges or chimneys.

 

Ensuring that you cure your oven when its new or if the oven has not been used for a while or if it’s damp, is the correct way to progressively heat the interior and exterior of the oven, so the joints and structures adapt better to the changes in temperature and for any humidity to disappear before use.  After the curing process has been completed, one of the most typical types of cracks that may appear, are fine hair line cracks between the grout joints on the chimney archway and dome of your Fuego wood-fired oven or on the dome render of our clasico models.

We must stress that these cracks are only cosmetic and will not impact on the performance of your oven. If you cannot live with the look of them, we always include with the purchase of all our wood-fired ovens a repair kit to be able to fill all dome and grout cracks, created on the outside of your oven. Here’s our step-by-step guide on how to repair all cracks on the grout and/or dome of your Fuego wood-fired oven:

1. If it’s a hair line crack, start by opening the crack with the help of a screwdriver, until you have a crack wide enough to be able to fill it. For larger cracks on grout joints, ensure you remove any loose debris of render.

2. Brush or blow any excess of dust from the crack.

3. Wet the opened crack with a sponge to ensure the render mix sticks correctly.

4. In a plastic container, mix 100g of Fuego grout render mix or clasico dome render mix (for clasico models only) with 25ml of water (25%) and stir well until fully combined. Increase the mix quantity if you need to repair a larger number of cracks.

WARNING
Moisture is the worst enemy of a clay oven even though our ovens have been treated with a waterproof sealant. We recommend that once a year, you give the external dome of your oven a couple of coats of a clear waterproof sealant to prolong its waterproofing. Please note this only applies to our clasico and brick range of ovens.

My Fuego wood fired pizza oven...

“Our Fuego wood oven has transformed our restaurant! As a piece of kit, it is extremely versatile and controllable, allowing us to roast all of our meats and vegetables in the wood burning oven as well as using it as a charcoal grill during service. The flavour of everything coming out of the Fuego clay pizza oven is incredible due to the amazing smoky, charred tones added to the smell and taste of everything that’s cooked in it. It is not expensive to run as all the kiln-dried wood we use heats the wood fired pizza oven pretty quickly and it retains its temperature really well, only needing to add logs to the fire a few times over the course of service.”

My Fuego wood fired pizza oven...

“We wanted a traditional wood oven that ticked lots of boxes, for us it had to be made of brick for the authentic feel, have amazing functionality and great quality. Our Fuego clay pizza oven ticks them all. Our pizza nights are such a fantastic feature for the guests that stay in our holiday cottages and it’s a great way of bringing friends and family together for making those special memories. Highly recommended”
