Application

1. Pour the recommended minimum amount of water into a suitable, clean container/mortar tray.
2. While stirring slowly, slowly add the powder to the water.
3. Mix thoroughly for at least 3 minutes.
   If necessary, to achieve the desired consistency, additional water may be added during mixing, but the maximum amount of water given should not be exceeded.
4. Adjust to the desired consistency to obtain a smooth and homogeneous mixture.
   Consistency should be checked after each mix.
