| Over thinning of coating. | |
| Reduce with MIROSOL thinners as per instructions on the relevant product data sheet to achieve correct spray viscosity. | |
| Spray gun fitted with incorrect sized fluid tip. | |
| Use only correct spray tip size and replace spray gun tips on a regular basis to maintain consistent coating application. Contact your Mirotone representative for advice on correct tip sizes required for Mirotone coatings. | |
| Cold conditions slowing down solvent evaporation. | |
| Ensure all Mirotone coatings are applied at above 10ºC ambient temperature and with humidity conditions at less than 70%. | |
| Poor atomisation of sprayed coating. | |
| Adjust spray gun settings to achieve correct fluid atomisation. Contact your Mirotone representative if problem persists. | |
|
|
| Successful spray coating application techniques are learned through practice and experience. | |
| Incorrect handling of the spray gun - gun being tilted and not being square to substrate, leading to uneven film deposits. | |
| Refer to your coating equipment supplier for advice on correct spray application techniques. | |
