| A surface film which reduces gloss or depth of colour. | |

|
| Entraped moisture, incompatible solvents, waxes or other undesirable elements in the coating film. | |
| Ensure substrate is free from all contaminants. Use only approved Mirotone Thinners as per instructions on the relevant product data sheet. | |
| Over dosing clear coatings with certain UV absorber solutions can lead to a bloom deposit migrating to the surface of the coating which may re-appear after wiping off. | |
| Do not add any additives to Mirotone coatings unless advised by a qualified Mirotone representative. Obtain written instructions on the correct additive addition procedure. | |
| Premature application to oiled surfaces. | |
| Allow the coating to dry as per instructions on the relevant product data sheet, even if the oiled surface appears to be dry before the specified time has elapsed. | |
| Application under moist or humid conditions can result in a bloom, due to moisture settling on the surface, which can form minute microscopic depressions in the film. To the naked eye, these appear as a patchy appearance or uniform milkiness. | |
| Ensure all Mirotone coatings are applied at above 10ºC ambient temperature and with humidity conditions at less than 70%. | |
| Oil stains applied to damp wood give rise to blooming after a period, as the moisture gradually migrates into the film from the wood substrate. | |
| Use a correctly seasoned wood substrate, which has moisture content of less than 15% immediately prior to commencing with application of the Mirotone coating system. | |
| Blooming of nitrocellulose lacquers can be caused by faulty polishing solutions containing unsuitable waxes or solvents. These may penetrate and remain in the film leaving a slight haze. | |
| Contact your Mirotone representative for advice on which 3M Polishing Compound is best suited for cutting and polishing the applied Mirotone coating system. | |
