Guidelines for the use of defoamers in cement mortar: In the preparation stage, the dosage of defoamers should be determined based on the construction volume, generally adding 0.1% -0.5% of the cement dosage. Mix and stir, mix the defoamer with an appropriate amount of water evenly, and then add it to the cement and stir until there

are no bubbles. Construction application: Operate according to the normal construction process, pay attention to the condition of cement mortar, and adjust it in a timely manner.

matters needing attention:

Avoid excessive use, as excessive use of defoamers may lead to a decrease in the performance of cement mortar. Evenly mix to ensure that the defoamer is evenly distributed in the cement mortar, and avoid no foam or too much foam locally. Storage conditions: Defoamers should be stored in a cool, ventilated, dry place, away from direct

sunlight and high temperatures.
