Please Read the Following: Keys
to Using Disposable
Spray Foam Insulation Kits Note: The following instructions are not unique to Touch 'n Seal Spray Foam Kits. All brands of SPF Kits have similar requirements to those listed below, and special precautions must be taken when spraying spray foam insulation. ·
Operating
Instructions ·
Please
read through the manufacturer's operating instructions prior to using
any SPF kit. ·
Temperature,
Temperature, Temperature! ·
Temperature
- All SPF kits need to be conditioned to the proper temperature prior
to use. In general, optimal core temperature is 75-85 F. The
single most important factor is maintaining proper core temperature. Temperatures affect both the viscosity of the liquids and pressures in the tanks. Failure to maintain temperature within the acceptable ranges will result in inconsistent foam and lower yields. If your tanks have arrived off the truck cold it can take several days for the chemical to reach room temperature. ·
Shake
Well ·
Remove each tank from its box and rock back and forth on one bottom edge for at least 2 minutes. ·
Upright
Position ·
The
tanks must remain in the upright position (valve at the top) while
spraying foam or yield issues can occur due to off-ratio spraying. Placing each tank in its box will help to keep it upright. ·
Unspent
Tank Storage ·
Leave
a cured nozzle on the gun after use for storage. This provides a seal
for the hoses and gun so that air does not seep into the hoses
(which could potentially cause a slight hardening of one component or
the other inside the hoses). If this is not done, it is possible to
experience some yield issues with the foam or potentially even cause
a complete blockage in one hose. Purge hose/gun for 15 seconds every
7-10 days of storage between uses to keep the foam in the hoses
fresh, leaving the spent nozzle tip on the end of the gun after each purging. ·
Apply
foam in 1-2 lifts ·
Apply
foam in 1-2 layers per pass. If more than 1-2 is applied at one
time, the foam is compacted during spraying which can cause
yield issues. Foam sprayed thicker than 2 per pass will have a
higher density and therefore will cover less square footage.
