Preparation, mixing and application
01
Surface preparation
- Abrasive blast steel to Sa 2.5 with a 30–60 μm surface profile.
- Power-tool clean local repairs to St 3 after removing contaminants.
- Apply promptly after preparation; the source recommends within 8 hours.
02
Mixing and application
- Mix base and hardener 9:1 by weight for 3–5 minutes; the package label governs.
- Use mixed material within the source reference of 5–8 hours.
- Apply by brush, roller, air spray or airless spray.
