Rust, Cracks, and Costly Closures—Don’t Let Steel Deck Failures Drive Up Your Maintenance Budget.

Steel bridge decks and industrial steel plates face a relentless onslaught of destructive forces. As a contractor, facility manager, or procurement specialist, you are likely battling these common issues:

• Corrosion and Rust: Steel is vulnerable to water, de-icing salts, and marine environments. Rust compromises structural integrity and shortens the lifespan of the asset. You need a seal that provides a robust shield against these elements.
• Heavy Load Stress and Deformation: Repeated heavy vehicle loading causes significant stress. A rigid pavement system can crack or delaminate. You need a material with the flexibility to follow the deformation of the steel without failing.
• Surface Slipperiness: Wet steel decks become dangerously slippery, creating a high risk for vehicles and personnel. You need a high-friction surface that maintains grip, even in wet conditions, with a high skid resistance value (BPN 55-65).
• UV Degradation and Color Fading: Constant sun exposure can cause traditional coatings to chalk, fade, and lose their protective properties. You need a system with exceptional UV and aging resistance to keep its color and protection.
• High Maintenance Costs and Downtime: Frequent repairs mean lane closures, operational disruptions, and high long-term costs. You need a durable, long-lasting solution that minimizes maintenance and extends the service life of your bridge deck pavement.

Construction Process: Two Application Methods

A successful installation is as important as the material itself. KAIDA DurAcryl™ offers two proven application methods to meet diverse project requirements. The total system thickness typically ranges from 2-3mm for the spray system and 3-6mm for the aggregate system.

Method 1: Spray-Applied Texture System (MMA Spray System)

This innovative system creates a textured anti-skid surface without the need for separate aggregate broadcasting, eliminating concerns about loose particles and providing a pedestrian-friendly finish.

Step 1: Surface Preparation and Repair

• Clean the surface thoroughly, ensuring it is free of water, oil stains, dust, and附着物. Use a grinding machine on the surface if necessary.
• Remove thin layers of traditional materials through patching.
• Fill and level cracks and凹坑to create a smooth, even base.
• For steel surfaces, perform grinding and apply a surface primer (interface agent) to ensure proper adhesion.

Step 2: MMA Basecoat Application

• Apply the DurAcryl™ MMA base coat by trowel or squeegee at the specified rate.

Step 3: MMA Anti-Skid Spray Coating

• Spray apply the DurAcryl™ anti-skid texture coating. This specialized formulation creates an integrated textured surface without the need for separate aggregate broadcasting.
• Key Advantages of the Spray System:
  • No loose aggregate particles to worry about over time
  • Eliminates the problem of颗粒脱落common with broadcast systems
    -完全克服了传统撒砂型路面容易擦伤行人的缺点, providing a surface that is both slip-resistant and gentle on pedestrians
  • Significant labor savings by eliminating the aggregate broadcasting and recovery steps
  • Reduced material costs as no separate aggregate is required
  • Faster application with fewer steps

Method 2: Aggregate Broadcast System (Heavy-Duty Application)

For the most demanding heavy-load applications requiring maximum durability and the highest friction levels.

1. Surface Grinding and Scouring: The substrate (steel, concrete, or asphalt) must be properly prepared by grinding and scouring to achieve the correct profile and cleanliness. Existing anti-corrosion layers and waterproofing membranes are assessed as part of the base preparation.
2. Edge Masking: Apply masking tape along the edges of the work area. This prevents contamination of surrounding surfaces and allows for clear zoning during application.
3. MMA Basecoat Application: Apply the DurAcryl™ MMA base coat by trowel or squeegee to a thickness of approximately 1mm. The typical application rate for the MMA base layer is 2.5-3 kg per square meter.
4. Anti-Skid Aggregate Broadcasting: Immediately after applying the wet base coat, broadcast anti-skid ceramic or bauxite aggregate particles onto the surface to create a textured, high-friction layer.
5. Curing and Aggregate Recovery: Allow the base coat to cure for one hour. Once cured, sweep and vacuum the surface to recover any excess, non-embedded aggregate particles.
6. Topcoat Spraying: Apply the DurAcryl™ colored topcoat (finish coat) using a spray or roller method to lock in the aggregate and provide the final color and seal.
7. Final Curing: Allow the topcoat to cure. The system is typically ready for light traffic after a short period.
8. Project Completion: After final curing, the new, durable, and anti-skid bridge deck pavement is complete and ready for service.

*Note: For steel decks, proper underlying preparation including rust removal by sandblasting, anti-corrosion layers, waterproofing membranes, and rapid repair mortar leveling courses (typically 5-10mm thick) should be addressed prior to starting the DurAcryl™ top system application. The system can be applied to steel substrates, concrete substrates, or asphalt.*
