To ensure the best effect of defoamers in gypsum self leveling construction, the following usage methods should be followed:

Add in moderation, accurately measure according to the manufacturer's recommended ratio, and avoid excess or deficiency. Gradually add defoamer during the mixing process to ensure that it is thoroughly mixed with the self leveling material. Moderately extending the stirring time can help the defoamer fully exert its effect. Construction

should be carried out as soon as possible after mixing is completed to reduce the chance of air bubbles being re generated. Maintain appropriate temperature and humidity in the construction environment to avoid external interference.
