    1. APPLICATION INSTRUCTIONS FOR BASE COATS

    (To the cleaned/sealed mold surface)

    • Using a wetted clean cotton cloth or fine mist spray pattern, wipe or spray on a smooth, wet, (not runny) continuous film over the entire mold surface.
    • With a second, clean, dry cotton cloth, wipe off any excess on the mold surface (usually the case for heavy application or cold molds).
    • Allow film to dry and cure for 10 minutes.
    • Apply a total of 3-5 coats per the above instructions.
    • Allow final coat to cure for 30 minutes at room temperature. Cure is instant at 250°F or higher.
    1. TIP:
    • If final time can be extended to one hour or longer at room temperature or mold can be heated to 150°F or higher for 30 minutes, this will further enhance the quality of release and the number of releases between applications.
    1. STORAGE:
    • Do not store above 49°C/120°F.
    • Keep gallon tightly sealed to prevent evaporation or contamination.
    • If stored in cold temperatures, allow to warm to room temperature before using.
