Coverage Guide Supplement Foreword
The following information is given to provide assistance to users of the GALV TECH range of aerosol products, for the purpose of obtaining correct dry-film thickness (for individual coats) according to the manufacturer and subsequently to obtain the total dry film thickness as required by BS/EN/ISO 1461. For the best performance, it is better to apply several thin coats than a single thick coat, in that the integrity and life of the final coating will be much improved.
Following surface preparation (see method statement), the products should be applied as follows, to achieve approx. 30-40um average per coat.
From approx: 20cm (8ins) at 6cm (2.5ins) per second and 1½ times passes, ie:
It is also considered good practice to spray individual coatings at 90 degrees to the preceding coat, ie:
| BS/EN/ISO 1461 Material Thickness | Recommended Galv Film Thickness | Recommended Repair Media Thickness |
| to 1 mm | 50um | 80um |
| 1 to 3 mm | 55um | 85um |
| 3 to 6 mm | 70um | 100um |
| from 6 mm | 85um | 115um |
The responsibility to ensure safe working conditions within the workplace remains with the user. The health hazards and safety precautions required for individual products should be assessed prior to use.
