Inspection and Repair
| Inspection | The finished coating must be visually inspected for any defects, such as runs and sags, fisheyes, blistering, pinholes, missed spots and possible contaminants. Pinhole/Holiday detection must generated according to NACE SP0188. |
| Coating Thickness | The coating thickness (DFT) must be within the specified DFT range. Use calibrated equipment and measure according to SSPC-PA 2 or other specified standard. |
| Repair | Pinholes/Holidays must be located and repaired with approved material. Consult Powercrete® for specific information. Retest the repaired area |
Cleaning & Handling
| Cleanup | Use Acetone or MEK. |
| General | Transport and stacking is possible after full cure of the coating and generating a Holiday test (NACE SP0188). This time can be reduced by increasing the curing temperature. Consult Powercrete® for specific information. |

* If the surface to be coated is below 10˚C (50˚F), preheating of the substrate is recommended.
Preheat temperatures should not exceed 80˚C (176˚F). Prior and during the application, the
temperature of the substrate must be at least 3˚C above the dew point.
Application Instruction: Plural Component Spray
| Step1 | Mix the Part A and B until uniform in consistency |
| Step2 | Use only heated plural component Airless equipment capable to maintain a 2:1 ratio in volume and 1.25 Gallon/4,73 Liter per minute output, with heated drums, insulated (heated) hoses and minimum 193bar (2800psi.) fluid pressure for Part A and 193bar (2800psi) for Part B. Use Binks 1M Airless spray-gun or equal with preferably changeable spray tips. Consult Powercrete® for specific information. |
| Step3 | Part A must be heated up and maintained to a temperature of 60-65˚C (140-150˚F) and Part B must be heated up and maintained at 38-49˚C (100-120˚F). |
