Fire Block Foam Block Foam e Fire B e B e B Fire Block Foam e B e B e Made in USA DIRECTIONS: Important - read all directions and cautions before use. Always wear gloves, eye protection and work clothes. Use drop cloths. Product is flammable during dispensing - turn off sources of ignition prior to use. Preparation: To promote adhesion, surfaces must be free of oil and dirt. Assemble straw and adapter, then carefully screw this trigger assembly onto valve. With trigger assembly attached, shake well for 30 seconds. Holding the can upside-down, slowly activate trigger until foam begins to dispense. Important: Before starting the job, first practice dispensing onto scrap materials. For best results, apply in temperatures between 65-100F (18-38C). Application: This product should only be dispensed in the UPSIDE-DOWN position. For best results, apply in spaces with 40% or greater relative humidity. Fill gap no more than 1/3 full, allowing room for expansion. Do not overfill. Important: Foam will continue to dispense for a few seconds after releasing the trigger - keep the straw tip moving to reduce the possibility of overfilling. Foam is tack-free in 30 minutes. Excess foam can be trimmed, sanded, caulked or plastered as necessary. Direct sunlight discolors foam if not painted or covered. Clean-up: If wet foam contacts skin, clean immediately with acetone or nail polish remover containing acetone - do not use water. Clean uncured foam with CRC Natural Degreaser. Do not attempt to remove cured foam with solvents - cured foam wears off and is not harmful to health. Storage/Re-Use: To store unused portion, bend straw back onto the knob atop the dispensing trigger. To re-use, remove the straw from the knob, shake well and apply as directed. Store can upright below 90F (32C).
