Application

ALWAYS WEAR PROTECTIVE GLOVES.

Shake can well before use (about 20 times).

For the FILL AND FIX PRODUCT, carefully fix nozzle. Do not overtighten or force.

ALWAYS USE CAN UPSIDE DOWN. For GUN GRADE, tighten securely into one of our range of guns.

Only partially fill cavities as the foam will expand to fill the remaining space. Any excess foam can be removed whilst still wet with EVERFLEX FOAM CLEANER. Cured foam must be removed mechanically. When used for fixing door frames, supports must be used until the foam is fully cured.

Please note:

When transported in cars, keep in boot, out of direct sunlight.

When removing cured foam from skin, take care not to damage with abrasives.

Grease skin with body lotion or similar.

IMPORTANT – Re-use is only possible by cleaning the nozzle and valve tip with EVERBUILD DUAL PURPOSE FOAM CLEANER before the foam has cured. Do not push any object into the valve as the contents may explode.

Storage

Store upright between 20 and 25^oC Pressurized container. Protect from sunlight and do not expose to temperatures above 50^oC. Do not pierce or burn the can even after use. Store as flammable liquid.

Note: Elevated temperatures will reduce shelf life dramatically.
