Depending on the size, we recommend allowing at least a full day to build the oven and an additional day for a skilled renderer to render the oven.
The oven will need to be completely dry before use which can take up to 4 days. Refer to ‘first fire up’ advice on the steps to getting the oven up to temperature for the first time.
Render advice
We would recommend when rendering to ensure that each layer is still damp before applying the next layer. If the render has dried too much before the next layer is applied, it may not bond correctly. Ensure intense/direct sunlight is avoided as this can dry the render too fast. We recommend that heavy rain is also avoided as this can saturate/spoil the render.
