Holdover Time is in the format of Hrs:Min's

These times are what I use, your company maybe something different.
To simplify type I & type II fluids, Type I is what you find in the old eastern block countries. Type II is What's found in the western world, 99.9%r of the time it's Killfrost ABC
** NOTE**
1. Killfrost ABC will not mix with cold water.
2. Add Killfrost ABC to hot water NEVER cold water to hot Killfrost ABC
3. Never heat Killfrost ABC water mix above 85 Deg C

Some general notes about application
Always apply fluid as close to the aircraft as possible to reduce heat loss
Surfaces must be sprayed symmetrically to ensure aerodynamic safety ie. Both wings, both stabilizers.
Never anti-ice twice. If necessary always apply hot de-ice mix before second anti-ice application.
Ensure Aircraft structure free from ice
