• Ensure surfaces are clean and free of dust, oil and grease. For best performance, moisten surfaces by spraying with water
• WEAR GLOVES AND EYE PROTECTION as Polyfilla Expanding Foam is difficult to remove from skin and clothing.
• Shake can vigorously for 60 seconds and screw applicator nozzle onto the can valve (do not over tighten). Turn can upside down.

• In exterior applications it is recommended to paint over to improve service life.
• If attempting to block entry of rats or mice, install small mesh bird wire before applying the foam, so that the wire is embedded inside the cured foam.
