Description
POLAGARD AG
High-Performance Anti-Graffiti Protective Coating
POLAGARD AG is a clear premium, high-performance aliphatic urethane coating engineered to cure into an extremely tough, durable, and long-lasting protective barrier. Designed for demanding public, commercial, and infrastructure environments, it provides superior resistance to graffiti, vandalism, weathering, chemical attack, and surface abrasion.
Once cured, POLAGARD AG forms a resilient, protective film that allows repeated graffiti removal without damaging the coating or underlying substrate. Its advanced formulation helps extend the service life of treated surfaces while maintaining long-term performance under heavy exposure conditions.
Designed to meet or exceed Department of Transportation requirements, POLAGARD AG is suitable for use on soundwalls, bridges, Jersey barriers, and other high-visibility infrastructure surfaces requiring maximum protection and durability.

POLAGARD AG Application Guideline
Clear Finish Preparation
- The substrate must be clean, dry, and free of loose particles, oil, grease, or any contaminants that may interfere with proper adhesion.
- Complete all repairs prior to the application of POLAGARD AG. All repair materials must be fully cured or set before coating application to prevent adhesion issues or discoloration.
- EIFS and other substrates that may be sensitive to solvent exposure should be sealed with CLEARCOAT AQ.
- Concrete and other cementitious materials must be properly cured, typically a minimum of 28 days.
Colored Finish Preparation
The substrate must be clean, dry, and free of loose particles, oil, grease, or any contaminants that may interfere with adhesion.
All repairs must be completed and fully cured prior to application of POLAGARD AG to avoid poor adhesion or discoloration.
- Prime metal surfaces with POLAPRIME 21
- Prime wood and mineral composite surfaces with POLAPRIME 2
- Refer to applicable POLAPRIME data sheets for additional substrate-specific recommendations
Previously painted surfaces should be tested for compatibility. Best results are generally achieved by complete paint removal without damaging the substrate.
Some painted surfaces may require treatment with POLAPRIME 7 to prevent bleed-through or staining.
After surface preparation is complete, apply one coat of WEARCOAT 44 at a coverage rate of approximately 200 square feet per gallon.
Application of Top Coats
Add POLAGARD AG Part A to Part B and mix thoroughly for a minimum of 3 minutes using a mechanical explosion-proof (EP-rated) mixer.
Allow entrapped air bubbles to dissipate before application.
Apply POLAGARD AG using a brush, roller, or airless spray equipment.
Porous or highly textured substrates may require two or three coats to achieve complete protection. Applications over WEARCOAT 44 typically require one coat unless the surface is heavily textured, in which case two coats may be necessary.
Allow a minimum of 6 hours cure time before recoating. Recoat within 72 hours. If this window is exceeded, sanding, sweep blasting, or other abrasion methods may be required to ensure proper intercoat adhesion.
Spray Application
Use a 30:1 airless pump with a 1/2″ hose, 3/8″ whip, and a 35–41 tip size.
Recommended Thickness
Two coats yield approximately 18–26 mils dry film thickness (DFT).
Drying Time
Approximately 6 hours at 70°F (21°C) and 50% relative humidity.
Cure Time
Approximately 72 hours at 70°F (21°C) and 50% relative humidity.
Clean-Up
Clean tools and equipment with xylene or toluene solvent.
Limitations
- Do not apply to frozen surfaces.
- Do not apply unless temperatures can be maintained above 40°F (4°C) for at least 8 hours.
- Surface temperatures must remain at least 5°F (3°C) above the dew point during application and curing.
- Protect the application from precipitation for a minimum of 4 hours.
- Do not allow moisture contamination of the product.
Maintenance
To remove graffiti, use an environmentally approved cleaner.
For repair of any damage to the coating system, contact the Andek Technical Department for assistance.
Storage
Store in a dry area away from direct sunlight and protect from freezing. Keep containers tightly sealed.
Shelf life is approximately 2 years from the date of manufacture when stored in original, factory-sealed containers between 40°F (5°C) and 90°F (32°C).
Disposal
Dispose of waste in accordance with all applicable federal, state, and local environmental regulations. Incineration is the preferred method of disposal.
Safety Information
Read the product label and Safety Data Sheet (SDS) prior to use for important health and safety information.
Keep out of reach of children and pets.
