Directions for use

•  READ ALL DIRECTIONS AND SAFETY DATA ON BOX BEFORE USE. ALWAYS WEAR GLOVES, EYE PROTECTION AND WORK CLOTHES. USE DROP CLOTHS.
• Apply ONLY in temperatures between 16° – 32°C.
• Product is flammable during dispensing – turn off sources of ignition prior to use.

• PREPARATION: To promote adhesion, surface must be clean, dry, and free of all foreign material. All substrate surfaces should be above 16°C for at least 24 hours prior to application. Variance outside of the recommended temperature can drastically affect the adhesion and yield of your foam kit.
• CLEAN-UP: If wet foam contacts skin, clean immediately with a dry rag – do not use water – water accelerates curing. Cured foam must be removed mechanically from surfaces. Uncured foam can be cleaned from most surfaces with Foam Cleaner or acetone.

IMPORTANT Check temperatures before use! CANISTER TEMPERATURE 16° – 32°C SURFACE TEMPERATURE 16° – 32°C AIR TEMPERATURE 16° – 32°C
