Solution: Check if the defoamer model is suitable, adjust the dosage or replace with a more efficient product; Ensure thorough mixing and extend the mixing time.

Problem 2: Incompatible with self leveling materials

Solution: Conduct compatibility testing and select defoamers with good compatibility; Or consult the manufacturer for professional advice.

Problem 3: Pinholes and shrinkage holes appear after construction

Solution: Analyze whether it is caused by excessive defoamer and adjust the amount added; Check whether the self leveling material ratio is reasonable and optimize the construction process.
