Installation Guide

Straw-applied version:
1. Shake can vigorously for 1 minute
before dispensing and between
uses.
2. Attach the nozzle by twisting it
clockwise into the valve. Press the
button until the appropriate size
of foam bead is achieved. Fill gap
less than 1/3 full to allow for proper
expansion.
3. If gap is overfilled, stuff excess
cured foam into gap with a blunt
tool or trim away with a sharp knife.
Foam can be be trimmed in 30
minutes.
4. Clean straw periodically by rubbing
the end on soft wood to free it from
foam.
5. When finished, bend the straw
back onto the plug on top of the
trigger assembly. The plug prevents
moisture from entering and curing
inside the straw or valve.
6. To use after storage, gently rotate
or twist the straw to break the
adhesive bond of the foam. Pull the
straw off of the plug and dispense.
