|
| Formation of breaks in a coating film that exposes the underlying substrate or coating (also called crazing or mud cracking). | |
|
|
|
| Application of two pack coating systems over single pack coatings. Coatings of similar elasticity should be applied. | |
| Apply only approved Mirotone coating systems as per instructions on the product data sheets. | |
| Previous coat not properly dry. | |
| Do not recoat until the elapsed drying time has been reached as per instructions on the relevant product data sheet. | |
| Coating application to unseasoned wood. | |
| Use correctly seasoned wood substrates that have moisture content of less than 15% immediately prior to commencing coating operations. | |
| Coating application to dimensionally unstable MDF board causing edge cracking. | |
| When coating MDF board, maintain dimensional board stability through atmospheric temperature control before the application of a Mirotone coating system. | |
| Attempts to cover cracks in the substrate by using excessive build up of coatings. | |
| Fill all cracks, holes, splits etc with MIROPUTTY 1600 wood filler prior to the application of a Mirotone coating system. MIROPUTTY 1600 is available in a range of wood tone colours to suit most practical applications. | |
| Inadequate stirring of coating leading to incorrect film properties. | |
| Always thoroughly stir Mirotone coatings prior to application preferably using a power stirrer. Alternatively use a 20mm wide stirring stick, using a lifting motion to ensure that the contents at the bottom of the can are thoroughly mixed in. | |
