Outdoor Oven Cement is a dry-mix mortar for compatible exterior refractory construction. Before starting the brickwork, check the layout, specified joints and expected working conditions. A March schedule should include time to protect the fresh masonry and allow it to set, as well as the construction day itself.
Match the mortar to the joint
Vitcas Outdoor Oven Cement has a stated resistance up to 1200°C and applications including suitable pizza ovens, barbecues and garden fire features. Once correctly set, it is water-insoluble. The complete construction still needs suitable drainage and weather protection.
Check the joint requirements in the selected design. Poorly fitted bricks should not leave large gaps that are then filled with excessive mortar. For larger specified refractory fills, the manufacturer identifies other applications, including Heatproof Screed.
Prepare the bricks before mixing
Dry-fit the components and remove loose material and contamination. Prepare the bricks, including the wetting required by the product instructions, before measuring the dry mix and water.
Mix the dry contents first, then add water as specified in the current data sheet to obtain a workable trowelling consistency. Making the mix excessively wet makes joint control harder; it does not increase the correct coverage. Do not add arbitrary pigments or another cement.
Allow for cold weather and work breaks
Lower temperatures can extend setting. Protect fresh masonry from unsuitable weather according to the material instructions and the design. A hard-looking outer joint alone does not establish that the oven is ready for firing.
Record the date, product variant and working conditions. Plan initial heating for the complete oven, including moisture held in the bricks and other new layers. Drying and commissioning remain separate from the mortar setting itself.
