SureCrete’s Dura-Kote DK 120™  is a specially formulated 67% solids hybrid solvent based polyaspartic coating designed for application over interior concrete, cement-based overlays, or as a top finish coat on epoxy systems. DK 120 provides a low VOC (330 g/L), UV stable, penetrating, film forming, color enhancing, and high gloss wears surface. The high-performance clear top coat generates the premier balance of strength, flexibility, chemical and scratch resistance. As a vertical wall coating, it enhances anti-graffiti properties. Dura-Kote 120 rapid cure time eliminates excessive waiting to return a floor to service. Unlike many polyaspartic’s, it has a user-friendly pot life of approximately 20 – 30 minutes. Turnaround time for a floor may be as little as 5 – 6 hours. It is ideally suited for both commercial and residential settings: aircraft hangars, clean room floors, manufacturing facilities, warehouses, bars, clubs, retail stores, automotive showrooms, residential interiors, garage floors, stadiums, or any high traffic area where an exceedingly resilient floor is desired.

When dealing with commercial applications where complete business shutdown is not a feasible option, polyaspartic coatings provide a much-needed solution. When the floor is prepped properly for these coatings, they can be applied overnight in a very small application window to ensure that no time is lost for the business. This is especially necessary for retail and restaurant or bar locations that can’t afford to close for even one day. Not only are polyaspartic’s very quick to apply, but they also offer an astounding amount of chemical and abrasion resistance. These properties also make DK 120 an ideal coating for DIY homeowners who only have a short period (usually one day/night on the weekend) to get their project finished.


MIXING RATIO | 4:1 (4 part A to 1 part B)

COVERAGE | Varies upon substrate: approximately 300 – 400 ft² per gal. (28 – 37 m² per 3.8 liter) 4 – 5 mils wet; 2.7 – 3.5 mils cured



Avoid application on extremely hot days or during wet, foggy weather. Basic rules include:

  • Apply with ambient and surface temperatures ranging above 32°F (0°C) and below 90°F (32°C) and that will remain within ranges for at least 12 hours following application.
    Note: as temperature falls below 60°F (10°C) part B will “thicken”. To empty part B from container will require moving into a heated space until the viscosity allows product to pour.
  • Surface temperature must be a minimum 5°F (3°C) above dew point.
  • Relative humidity should be below 75%.
