Accurately add defoamers according to the manufacturer's recommended dosage to avoid excessive or insufficient use. Slowly add the defoamer to the cement mortar and mix while adding to ensure even mixing. After mixing, let it stand for a period of time, observe the elimination of bubbles, and adjust the dosage if necessary.

Construction should be carried out under suitable temperature and humidity conditions to avoid the impact of harsh environments on the defoaming effect. Use appropriate mixing speed and method to ensure that the defoamer is fully mixed with the cement mortar. The mixed cement mortar should be used as soon as possible to avoid the

regeneration of bubbles caused by prolonged storage. During and after the construction process, the compactness, strength, and surface quality of the cement mortar shall be tested to ensure the defoaming effect.
