Henan Sinowin Chemical Polyvinyl alcohol powder (PVA1788, 2488) is a commonly used building mortar additive. They can be used in conjunction with cellulose ether water-retaining agents to improve the flexibility, water-retention and viscosity of cement mortar and gypsum building materials, and reduce friction, thus Enhance work efficiency and quality. In addition, they can prevent cracking and falling off of the plaster layer, increase adhesion strength and smoothness, and improve the overall performance of building mortar.

Building mortars using polyvinyl alcohol powder (PVA1788, 2488) should be added in a certain amount. The specific usage instructions are as follows:

 1. For PVA2488 as cement-based water-resistant putty, tile adhesive and interface agent, the recommended addition amount is between 0.3% and 0.8%, accounting for the proportion of the total formula;

2. For pva1788 as an additive for cement and gypsum putty, the recommended addition amount is also between 0.3% and 0.8%, accounting for the proportion of the total formula.

In general, using polyvinyl alcohol powder (PVA1788, 2488) as an additive for building mortar can greatly improve the performance and quality of building mortar, making it more applicable and practical.
