Redispersible Polymer Powder (RDP), is a water-soluble polymer powder that transforms into a liquid emulsion when mixed with water, mirroring the original polymer dispersion. Think of it as a powdered adhesive that "comes back to life" upon hydration.
In the context of repair mortar, RDP functions as a vital binding agent and performance enhancer. It substantially boosts the mortar's capacity to resist water penetration, firmly adhere to various surfaces, and endure structural stresses. Ultimately, it is a key ingredient in achieving repairs that are both durable and long-lasting, especially in moisture-prone environments.
Imagine a concrete surface riddled with microscopic cracks and pores, creating pathways for water to infiltrate and cause damage. Traditional repair mortars often struggle to effectively fill these tiny gaps and lack the flexibility to accommodate movement, leading to recurring cracks. RDP addresses these problems through a multi-stage process:
RDP-modified repair mortars can be customized to meet specific application needs by adjusting the type and dosage of RPP used. Here’s a breakdown of common grades, helping you choose the correct RDP grade for your repair mortar:

Selecting the right RDP grade is essential for achieving optimal performance in your repair mortar. Consider these factors when choosing:
| Condition | Recommendation |
|---|---|
| Dry Interior Environment | ZOVAE ZW5026N (for general improvements in workability and adhesion) |
| Damp Exterior Environment | ZOVAE ZW9032H (for enhanced flexibility and water resistance) |
| Harsh Marine Environment | ZOVAE ZW9035H (for superior waterproofing, alkali resistance, and long-term durability) |
| Large Crack Repair | ZOVAE ZW6045N (due to its enhanced flexibility) |
| Thin Layer Application | ZOVAE ZW6028N (promotes good adhesion on thin applications) |
| Problem | Solution |
|---|---|
| Premature Cracking | Problem: Mortar cracks due to shrinkage or substrate movement. Solution: Incorporate ZOVAE ZW6045N to enhance flexibility. |
| Poor Adhesion to Existing Concrete | Problem: Mortar fails to bond properly, leading to delamination. Solution: Use ZOVAE ZW6028N to improve adhesion to the substrate. |
| Water Ingress and Damage | Problem: Water penetrates the mortar, causing freeze-thaw damage and corrosion. Solution: Utilize ZOVAE ZW9035H for superior waterproofing. |
Success Key: Ensure thorough mixing to fully redisperse the RDP and achieve optimal performance. Always consult the product’s technical data sheet (TDS) for specific recommendations.
