2. It is necessary to pay attention to the appropriate amount of water added to avoid the mixture being too thin and affecting the construction effect.
3. When using a hand mixer, you need to stir vigorously and evenly to avoid uneven mixing.
4. When using the electric mixer, it should be noted that the mixer should be operated in accordance with the requirements in the manual to ensure personal safety and the normal operation of the equipment.
