Precautions when using redispersible powder

The redispersible latex powder mainly plays the role of toughness and strength in the construction project. The effect of the general addition amount to a certain degree of strength will be good, but the following problems should be paid attention to during the use of the product:

1. It is not advisable to invest in one time;

2, stirring and mixing evenly, but the mixing time should not be too long, 15 minutes is appropriate, long time mixing sand and cement easy to precipitate layering (vertical mixer special attention);

3, need to adjust the amount of additives according to seasonal changes;

4. Avoid the agglomeration of additives or cement;

5. When polypropylene fiber needs to be added, it should be placed in the cement to disperse, because the fine particles of cement can eliminate the static electricity of the fiber, so that the polypropylene fiber can be dispersed;

6. It is strictly forbidden to mix and use with acidic substances;

7. It is forbidden to be used in construction below 5 °C. The low temperature construction will cause the biggest engineering quality problem, which will result in the non-adhesive bonding between the plaster and the thermal insulation board. This is an engineering quality problem with no remedial solution in the later stage.
