Unique Characteristics

• Ease of Use: Extended working time for easier application in larger areas.
• Customizable: Tintable with ASTC pigments and available in low-odor versions.
• Non-Skid Options: Incorporate ASTC’s “SSR” aggregate for additional safety.
• Durability: High-build protection for floors with superior elongation and flexibility.

Advantages

• UV stable and non-yellowing.
• High stain resistance, including resistance to plasticizer migration from tires.
• Excellent chemical and abrasion resistance.
• Superior adhesion to concrete and existing topcoats.
• Waterproof and elastomeric properties for robust performance.
• Quick turnaround for floor applications.

Applications

5500 EX is ideal for:

• Decorative concrete floor finishes.
• Industrial, commercial, and residential floor coatings.
• Clear topcoats for color chips and quartz.
• Kitchen floors, slabs, stairs, and pedestrian walkways.
• Exterior applications requiring UV stability.

Preparation

1. Concrete Curing: Ensure a 28-day cure period.
2. Surface Cleaning: Remove all contaminants, including oils, wax, and curing agents.
3. Profile Creation: Abrade the surface to create a rough profile of 2-3 mils (ASTM D4259).
4. Moisture Testing: Ensure moisture vapor transmission (MVT) does not exceed 3 lbs per 1,000 sq ft per 24 hours.

Priming

• Self-Priming: 5500 EX can be applied directly to concrete.
• Optional Primers: Use ASTC’s 6000 Series Epoxy Primer, 7001 Pen Prime, or 8000 CMW as needed.

Application

1. Mixing:
   • Combine components A and B at a 1:1 ratio using a jiffy mixer.
   • Mix for 1-2 minutes without incorporating air.
   • Add pigments if required, ensuring uniform dispersion.
2. Coating:
   • Apply with a notched squeegee and back-roll with a 1/4”-3/8” nap roller.
   • Maintain a thin coat (5-10 mils) for best results.
3. Recoat Timing:
   • Recoat within 1-2 hours or after light sanding if exceeded.

Special Considerations

• Cold Conditions: Use 5500 Fast Set for applications below 50°F.
• Hot Conditions: Use 5500 HH or HHH in environments above 85°F with high humidity.
• Chemical Resistance: Resistant to a wide range of chemicals, including acids, ethanol, and motor oil.

Limitations

• Avoid application on wet surfaces or in environments with high moisture vapor drive.
• Not all tires are tested for plasticizer staining.
• Store kits in a cool, dry environment away from sunlight.
• For professional applicators only. Refer to the MSDS before use.
