Application Information

SUBSTRATE PREPARATION
Surfaces must be sound, clean, and free of oil and grease. Spray small amounts of water onto the substrate prior to the application. For cold applications, Flexfoam Hand 375 must be kept in a warm room where the temperature does not exceed 30°C before the application.

APPLICATION
Shake Flexfoam Hand 375 well before using, then attached the straw to the aerosol can valve.
The discharge rate can be controlled by controlling the pressure on the trigger. Fill half of the cavities' volume and leave the foam to expand in the joint, then refill as necessary. Flexfoam Hand 375 aerosol can must be kept upside down during the time of discharging.
