Only One Chemical is Dispensing

To assist you in this section, identify the "A" component as being the darker brown liquid and the "B" component as being white or nearly clear in color.

Most often when there is only one chemical coming out of the gun, it will be the "B" component, or whiter chemical. This is usually caused by not using the gun on a regular basis, causing blocking on one side of the gun.

The "A" component is very sensitive to humidity. When exposed (and it can be exposed through the hoses), it forms small dark crystal that form on the inner side of the hoses or in the small spaces between the inner workings of the dispensing gun. If you use the gun a MINIMUM of once per week (even more often in humid climates), the constant flow of chemical will eliminate these crystals from forming. If the gun and hose assembly sits for too long, these crystals form, and when you pull the trigger the next time, they either create a blockage or completely freeze up the inner works.

To prevent this from happening, USE THE GUN AT LEAST ONCE PER WEEK (more often in humid climates).

To fix the problem, you will need to purchase a new gun and hose assembly. See the Troubleshooting Video (WMV - Flash) for the procedure on how to change the gun and hose assembly.

Cleanup of "B" component can be accomplished using soap and water, however, get it while it is still in the liquid state.

If only "A" component is coming out, and this very rarely happens, something has occurred to freeze up the "B" component side of the gun. Most likely, the gun and hose assembly had been sitting much too long between applications. You will need to purchase a new gun and hose assembly and install it on the kit (view the Troubleshooting Video (WMV - Flash) for the procedure).

Cleanup of "A" component is very tricky. DO NOT USE WATER TO CLEAN UP THE "A' COMPONENT CHEMICAL. Be sure to wear nitril or butyl rubber gloves and proper respiratory equipment. For a small amount of chemical, saturate a rag with dish soap and wipe it up. Be sure to do this while the chemical is still liquid. And be aware that there will most likely be a stain. For larger amounts of chemical, refer to the Material Safety Data Sheet, Section 6 for instructions to deal with a chemical spill.

To be sure that both chemicals are dispensing from the gun PRIOR to your application, always do a test shot into a waste container prior to actually dispensing the foam. If the resulting shot looks suspicious, follow the procedure in Checking the Gun for Proper Function and/or view the troubleshooting video for step by step instructions.
