Hydrophobic Redispersible Polymer Powder (RDP): ZOVAE's Premium Waterproofing Solution

What Is Hydrophobic Redispersible Polymer Powder?

Hydrophobic Redispersible Polymer Powder is a special dry additive that creates a water-repellent barrier in construction materials. Unlike regular RDP, the hydrophobic version contains silane-siloxane components that actively repel water. When mixed with water during application, it turns back into a polymer emulsion and forms a protective film as it dries.

Top Applications for ZOVAE Hydrophobic RDP Powder

Our Hydrophobic Redispersible Polymer Powder works wonders in many construction products. Here's where it performs best:

Wall Putty & Skim Coat

Adding ZOVAE Hydrophobic RDP to wall putty creates surfaces that resist moisture. It also:

  • Makes application smoother and easier
  • Reduces shrinkage by 20-30%
  • Increases flexibility for fewer cracks
Repair works with plaster

How ZOVAE Hydrophobic RDP Improves Your Products

Our Hydrophobic Redispersible Polymer Powder transforms ordinary construction materials in several important ways:

Water Protection

The hydrophobic film created by our RDP blocks moisture from penetrating surfaces. This protection is crucial for:

  • Exterior walls exposed to rain
  • Bathroom and kitchen surfaces
  • Basement walls facing ground moisture

Stronger Adhesion

ZOVAE Hydrophobic RDP significantly improves how materials together. This means:

  • Tile adhesives hold better, even in wet areas
  • Renders stay attached to walls longer
  • Less chance of delamination over time

Better Workability

Contractors love how our Hydrophobic RDP Powder makes materials easier to work with:

  • Smoother mixing with less effort
  • Longer open time for application
  • Easier spreading and finishing

Long-Term Durability

Buildings with ZOVAE Hydrophobic RDP in their materials last longer because they resist:

  • UV damage from sunlight
  • Freeze-thaw cycles that cause cracking
  • Mold and mildew growth

Frequently Asked Questions About Hydrophobic RDP

Hydrophobic Redispersible Polymer Powder contains special silane-siloxane additives that regular RDP doesn’t have. These components create a water-repelling effect that:

  • Reduces water absorption by up to 80%
  • Maintains performance in wet conditions
  • Provides better protection against moisture damage

The recommended amount of ZOVAE Hydrophobic RDP ranges from 0.5% to 5.0% of your total dry mix weight, depending on your specific application:

  • Wall putty: 1.0-2.0%
  • Tile adhesives: 2.0-3.0%
  • Waterproofing membranes: 3.0-5.0%

For personalized guidance, our technical team is happy to help you find the perfect dosage.

To maintain the quality of your ZOVAE Hydrophobic RDP:

  • Keep in a cool, dry place between 5°C and 30°C (41°F-86°F)
  • Store in tightly sealed original containers
  • Protect from humidity and direct sunlight
  • Use within 12 months for best results

When mixed with water, Hydrophobic Redispersible Polymer Powder returns to its original polymer form. As the material dries, it creates a flexible polymer film throughout the mixture. This film:

  1. Forms a network that blocks water penetration
  2. Improves bonding between cement particles
  3. Creates flexibility that prevents cracking
  4. Enhances overall durability of the finished product
