# Introduction
Re-dispersible polymer powder (RDP) has become an essential additive in modern construction projects. Its unique properties make it an excellent choice for improving the performance and durability of various building materials. In this comprehensive guide, we will explore the benefits of using RDP in construction and provide practical tips for its application.
## What is Re-dispersible Polymer Powder?
RDP is a free-flowing white powder obtained by spray drying a vinyl acetate-ethylene copolymer dispersion. It is commonly used as a binder in cement-based products to improve adhesion, flexibility, and water resistance. RDP can enhance the performance of mortar, tile adhesives, grouts, and self-leveling compounds.
### Benefits of Using RDP in Construction
- Improved adhesion: RDP enhances the bond strength between building materials, resulting in more durable structures.
- Increased flexibility: RDP improves the flexibility of mortar and other construction products, reducing the risk of cracking.
- Water resistance: RDP helps to repel water, preventing damage to the building materials.
- Enhanced workability: RDP improves the workability of cement-based products, making them easier to handle and apply.
#### Application Techniques
When using RDP in construction projects, it is essential to follow the manufacturer's instructions for the correct dosage and mixing procedures. Here are some general tips for applying RDP effectively:
1. Measure the correct amount of RDP according to the recommended dosage.
2. Mix the RDP with water before adding it to the other construction materials.
3. Ensure thorough mixing to achieve a uniform dispersion of the RDP.
4. Allow the mixture to rest before applying it to the substrate to ensure proper bonding.
