0-95% Relative Humidity

Drying Times

Curing Schedule
Surface Temp Dry to Recoat
5°C (41°F) 16 Hours
10°C (50°F) 8 Hours
16°C (61°F) 5 Hours
24°C (75°F) 3 Hours
32°C (90°F) 1.5 Hours

  • These times are based on 150 microns dry film thickness
  • Higher film thickness, insufficient ventilation or cooler temperatures will require longer cure times and could result in solvent entrapment and premature failure

Surface Preparation


  • Surfaces must be clean and dry
  • Employ adequate methods to remove dirt, dust, oil, and all other contaminants that could interfere with adhesion of the coating


  • Abrasive blasting to min. Sa 2½ (ISO 8501-1)
  • Alternatively, ultra high pressure water jetting to Nace No. 7 min. C Vis WJ-2. Max flash rust; C Vis WJ-2M


  • Normally applied over clean, dry recommended primer.
  • Can also be applied directly to concrete thinned 25%.
  • Concrete must be cured at least 28 days at 24°C and 50% relative humidity or equivalent.
  • Prepare surfaces in accordance with ASTM D42582 Surface Cleaning of Concrete and ASTM D4259 Abrading Concrete
  • Voids in concrete may require surfacing.

Application Methods

Product Information

Power mix separately, then combine and power mix


Thinning: May be thinned up to 15% with Carboline Thinner 2
Use of thinners other than those supplied by Carboline may adversely affect product performance and void product warranty, whether expressed or implied
Ratio: 1:1 Ratio (A to B)
Pot Life: Approx. 3 hours at 24°C – longer at lower temperatures
Airless Spray: Pump Ratio: 30:1 (min.)
GPM Output: 3.0 (min)
Material Hose: 3/8” I.D. (min)
Tip Size: 0.017”-0.021”
Output PSI: 2100-2300
Filter Size: 60 mesh
Brush and Roller (General): Not recommended for tank lining applications except when striping welds. Multiple coats may be required to obtain desired appearance, recommended dry film thickness and adequate hiding. Avoid excessive re-brushing or re-rolling. For best results, tie-in within 10 minutes at 24°C
Brush: Use a medium bristle brush
Roller: Use a medium-nap synthetic roller cover with phenolic core

Application Conditions

Product Conditions
Condition Material Surface Ambient Humidity
Minimum 10°C (50°F) 5°C (41°F) 5°C (41°F) 0%
Maximum 30°C (86°F) 50°C (122°F) 45°C (113°F) 85%

  • Industry standards are for substrate temperatures to be 3°C above the dew point.
  • Condensation due to substrate temperatures below the dew point can interfere with proper adhesion to the substrate.
  • Special application techniques may be required above or below normal application conditions.

Health and Safety

Clean Up

  • Use Thinner 2 or Acetone
  • In case of spillage, absorb and dispose of in accordance with local applicable regulations


  • Read and follow all caution statements on this product data sheet and on the SDS for this product
  • Employ normal workmanlike safety precautions
  • Hypersensitive persons should wear protective clothing, gloves and use protective cream on face, hands, and all exposed areas


  • When used as a tank lining or in enclosed areas, thorough air circulation must be used during and after application until the coating is cured
  • The ventilation system should be capable of preventing the solvent vapor concentration from reaching the lower explosion limit for the solvents used


  • This product contains flammable solvents
  • Keep away from sparks and open flames
  • All electrical equipment and installations should be made and grounded in accordance with applicable regulations
  • In areas where explosion hazards exist, workmen should be required to use nonferrous tools and wear conductive and non-sparking shoes
