Application&Usage Instructions

Application

Suitable for steel, wood, and aluminum molds.

Usage Intructions

1.    Dilution Ratios:
o    Aluminum mold: 1:10
o    Steel mold: 1:15
o    Wooden mold: 1:12
Stir well before mixing with water.
2.    Example (Steel mold):
Mix 1 part release agent with 15 parts water. Pour into a sprayer and stir evenly. Spray onto mold surface, ensuring even coverage. After spraying and a short wait (10–30 minutes), proceed with concrete pouring. If surface powdering occurs, increase dilution ratio to 1:16 for better results.

Construction Tips

1.    Always follow recommended dilution ratios; do not spray on wet molds.
2.    Spray only after the release agent is thoroughly applied and mold surface is dry.
Note: After spraying, mold surfaces may appear untreated. Do not wipe. The release agent creates an invisible film. If unsure, perform a spot spray test. Capture video to check smoothness and shine—adjust as needed for optimal results.
