  1. Surface preparation: Ensure that the surface to be repaired or lined is clean and free from dust, grease, and other contaminants. If necessary, use a wire brush or sandpaper to remove any loose material and ensure good adhesion.

  2. Mixing: Vitset 45 is a ready-mixed refractory cement and does not require any additional mixing. However, it should be thoroughly stirred before use to ensure a consistent texture.

  3. Application: Apply Vitset 45 using a trowel or spatula, pressing the material firmly into place. Ensure that the material is spread evenly and fills any gaps or cracks.

  4. Drying and curing: Allow the material to dry and cure for at least 24 hours at room temperature. Avoid exposing the material to moisture or high temperatures during this time.

  5. Firing: After the material has cured, it can be fired gradually to the desired temperature. Follow the firing schedule recommended for your specific application.

Note that these are general instructions, and specific instructions may vary depending on the application and conditions.
