Storage and handling
- Avoid generating dust during handling
- Clean up using vacuuming or sweeping
- Store bags off the ground with adequate air circulation
- Bags are not waterproof and must be protected from moisture
The shelf life of Hydrated Lime depends on storage conditions. When stored correctly and protected from moisture, bags may be stored for up to 12 months. Testing prior to use is recommended if the product age exceeds three months, or sooner if storage conditions have not been ideal.
Safety information
Prolonged exposure may cause drying or irritation of sensitive skin.
