For best results, maximum yield, and the best spraying foam, the chemicals in the tanks should be between 75 and 85 degrees Fahrenheit. In the summer and in warm climates, this is easy to do. In cold climates or winter months, we suggest you use a forced air heater of some sort to bring the chemicals up to optimum temp. Too hot or cold reduces yield!
Shake Them Up!
You should agitate the canisters to mix the propellant well before you start spraying. This insures that you get good pressure all the way to the end of the canisters. Simply rocking or rolling the larger tanks back and forth for a minute or two is sufficient. The A tank tends to need to be shaken longer than the B tank.
These tanks are pre-pressurized and like any pressurized tanks, there is more pressure when you first open them than there is near the end of the tank. The trigger on the application gun is metered in that the further you pull back on the trigger, the faster the chemicals dispense. Please adjust your flow to match your application goals.
Change Nozzle Tips
The nozzle tip on the end of the application gun is actually the mixing chamber for the two chemicals. This high tech nozzle is ribbed in such a way to create a mixing ‘vortex’ within the tip so well mixed foaming agents are dispensed for maximum results. Just as the foam rises and hardens in 30-45 seconds for the fast rise formula, it will do so in the tip if chemical isn’t being sprayed through the tip.
Once the trigger is squeezed it must be reactivated within 30 seconds or a new nozzle must be installed. The tips also need to be changed every 8 minutes of continuous spray time. Failure to do this could result in chemical leakeage that could ruin the dispensing unit and/or hoses.
