|
| Appying a second coat onto an intial coat which appears dry but has not yet built up solvent resistance. Solvents in the second coat reactivate and soften the first coat. | |

|
| Insufficient dry time between coats. | |
| Allow all Mirotone coatings to dry according to the instructions on the relevant product data sheet. | |
| Low temperature and high humidity in the spray booth and drying rooms. | |
| Ensure all Mirotone coating systems are applied at above 10ºC ambient temperature and with humidity conditions at less than 70%. In colder climates extend drying times by 50 to 100%. | |
| Excessive Wet Film Build causing slow drying of the coating. | |
| Apply all Mirotone coatings to the correct Wet Film Thickness as specified on the relevant product data sheet. | |
| Use of incorrect thinners. | |
| Use only the correct MIROSOL thinners as specified on the relevant product data sheet. | |
| Incorrect "B" Solution (hardener) used in a two pack coating system. | |
| Ensure the correct Mirotone components are used and mixed as per the instructions on the relevant product data sheet. | |
| Incorrect mixing ratio between Part A (Base) and Part B (Hardener) in a two pack coating system. | |
| Strictly follow measuring and mixing instructions on the relevant product data sheet. | |
| Using a two pack coating after the product's shelf life has expired. Once a coating has gelled it can not be rejuvenated by adding more thinners or more freshly catalysed material. | |
| Ensure adequate stock rotation to ensure oldest products are used first. | |
