There are numerous brands of cement mortar defoamers in the market, with differences in performance, price, service quality, and other aspects. When choosing, it is recommended to conduct a comprehensive evaluation from aspects such as brand awareness, user reputation, and product certification, and choose products with good reputation and reliable quality. Ensure that the product packaging has clear information such as manufacturer, production date, shelf life, etc. Verify key indicators such as defoaming ability, stability, and compatibility of the product through laboratory testing. Consult with technical personnel or industry experts to understand the actual application effects and precautions of the product.

Calculate and determine the appropriate amount of defoamer based on factors such as mortar type, dosage, and construction conditions before construction. Ensure that mixing equipment, conveying pumps, and other devices are in good working condition. Check the environmental conditions such as temperature and humidity at the construction site to ensure compliance with construction requirements.

When mixing mortar, gradually add defoamer according to the predetermined ratio and ensure even mixing. Avoid excessive mixing time that may cause the mortar to become too dry or have more bubbles. The mixed mortar should be used in a timely manner to avoid performance degradation caused by prolonged storage. During the construction process, pay attention to observing the air bubbles in the mortar, and if necessary, add an appropriate amount of defoamer.

Through the above guidelines, we hope to help you better understand and use cement mortar defoamers to ensure project quality and construction efficiency.
