Solvent-Free Epoxy Primer for Wet Concrete
Strong Bond Starts at the Base — Even in Wet Conditions
Solvent-Free Epoxy Primer for Wet Concrete Solutions
Concrete doesn’t wait for the weather — and neither should your primer. ZDSpoxy offers a high-performance solvent-free epoxy primer engineered to adhere securely to damp, wet, or green concrete surfaces, forming a reliable foundation for coatings, grouts, or injection systems.

Challenges in Real-World Sites
- 🌧️ Humid or rainy environments delay standard primer application
- 💧 Fresh concrete retains moisture long after curing begins
- 🦠 Moisture causes adhesion failure, peeling, or bubbling in topcoats
- 🧪 Many primers contain VOCs that limit use in closed spaces
ZDSpoxy’s Solution: ZDS2870AB
Our ZDS2870AB primer is designed to overcome these real-site problems:
- 💧 Adheres to moist, wet, or slightly oily concrete substrates
- 🛡️ Solvent-free, 100% solids formulation – zero VOC
- ⚙️ Forms chemical bonds with epoxy grouts or topcoats
- 🚫 Prevents water entrapment and blistering in top layers
- ⏱️ Fast-curing at 10–35°C, even in high humidity environments
Application Guidance
- Surface: Remove dust, standing water, and loosely bound particles
- Apply by roller or brush in thin layer
- Pot life: 45–60 minutes at 25°C
- Tack-free: ~2–4 hours; Topcoat window: 24 hours
- Compatible with ZDSpoxy grouts, coatings, and injection products
Compatible Systems
- ✅ Underwater epoxy coatings (ZDS2186AB)
- ✅ Heavy-duty epoxy grouts (ZDS1410AB / ZDS4130AB)
- ✅ Crack injection repair systems (ZDS2002AB)
- ✅ Self-leveling floor coatings (ZDS400-4)
FAQ
Can ZDS2870AB be applied on saturated concrete?
Yes, as long as standing water is removed and the surface is damp but not flooded.
Is it safe for use in food processing plants?
Yes. It contains no solvents or VOCs, making it suitable for closed or sensitive environments.
How long should I wait before applying the grout or topcoat?
Usually within 2–24 hours depending on temperature. Ideal when the surface is still slightly tacky.
