- Cleanup
- Clean all equipment immediately after use with International GTA220 or International GTA610. It is good working practice to periodically flush out spray equipment during the course of the working day. Frequency of cleaning will depend upon amount sprayed, temperature and elapsed time, including any delays.
- Thinning
- International GTA220 or Not normally required See Product Characteristics section for International GTA610 further details (International GTA007)
