Introduction
Redispersible Polymer Powder (RDP) is a water-soluble polymer produced from ethylene-vinyl acetate (EVA) copolymer through a spray-drying process. Designed specifically for the construction industry, RDP is used to enhance the properties of dry mortar blends. It is typically combined with HPMC/HEMC and other additives to improve the performance of cement-based or gypsum-based mortars, delivering benefits such as better water retention, extended open time, improved workability, increased adhesion to various substrates, and higher flexural strength and flexibility.
Among FORAWAD’s comprehensive RDP product line, the FWD 5111 model stands out as a versatile and high-performance solution for a wide range of construction applications.

| Repair Mortar / Crack Filler | ★★★★ |
| External Insulation and Finish Systems (EIFS) | ★★★ |
| Self-Leveling Compounds | ★★★★ |
| Masonry Mortar | ★★★ |
| Waterproofing Mortar | ★★★★ |
With top ratings (★★★★) in wall putty, tile adhesives, cement-based plasters, tile grouts, repair mortar, self-leveling compounds, and waterproofing mortar, the FWD 5111 proves to be an exceptionally versatile choice for construction professionals seeking a single RDP solution that performs reliably across multiple applications.
Key Performance Benefits
- Increased adhesive and cohesive strength – Ensures strong bonding to a variety of substrates, reducing the risk of delamination or failure.
- Higher flexural strength – Enhances the mechanical integrity of mortar, making it more resistant to cracking and deformation.
- Excellent rheology – Provides optimal flow and leveling characteristics, facilitating easy application and finishing.
- Improved workability – Makes the mortar easier to mix, apply, and spread, improving on-site efficiency.
- Great durability and abrasion resistance – Extends the service life of finished surfaces by withstanding mechanical wear and environmental stress.
- Improved water retention capability and open time – Allows sufficient working time for application and adjustment, even in challenging conditions.
- Water resistance and low water uptake – Reduces susceptibility to moisture-related damage, enhancing the long-term performance of the mortar system.
Packaging and Storage
Packaging: The RDP product is packed in three-layer paper bags with an inner polyethylene bag for reinforcement. Each bag has a net weight of 25 kg.
Storage: It should be kept in a cool, dry warehouse, away from moisture, direct sunlight, fire, and rain. Proper storage conditions are essential to maintain product quality and prevent premature agglomeration or degradation.
