Recommended Dosage: The general recommended dosage of redispersible latex powder in repair mortar is 5% to 10% of the dry mortar weight.
Precautions:
The specific dosage needs to be adjusted according to the type of repair mortar, its intended use, and the actual site conditions.
Excessive addition of redispersible latex powder will cause the mortar to become too soft, compromising its strength and durability.
Precautions:
The mixing time should not be too long to prevent sand and cement from settling and separating.
Adjust the dosage of the additive according to seasonal changes, and add an appropriate amount of HPMC to prevent the additive or cement from clumping due to moisture.
Do not mix or use with acidic substances.
Do not use below 5℃, as low-temperature construction will cause problems such as poor adhesion between the finishing mortar and the substrate.
Summary: By using the correct dosage and method, redispersible latex powder can effectively improve the performance of repair mortar, ensuring a strong and durable repair effect. During use, please follow the above steps and precautions to ensure construction quality and safety.
