  1. Surface preparation: Ensure that the surfaces to be bonded are clean and dry before applying Silcas A. Any loose debris, dirt, or grease should be removed using a wire brush or other suitable tool.
  2. Mixing: Silcas A is ready-mixed and does not require any additional mixing. However, if the mortar has been standing for some time, it may need to be stirred before use to ensure that it is well-mixed.
  3. Application: Using a trowel, apply Silcas A to the surfaces that need to be bonded. The mortar should be applied in a smooth, even layer, with enough pressure to ensure good adhesion.
  4. Curing: Silcas A will cure naturally at room temperature, but for best results, it should be allowed to dry for 24 hours before exposing it to high temperatures. After that, the mortar can be fired to the desired temperature.

Note: Silcas A should be stored in a cool, dry place and kept in its original container with the lid tightly closed to prevent it from drying out.
