Poor chemical flow. (Note: when injecting foam into a closed cavity, it is important to check frequently that the chemical is floring properly, and to replace any nozzle that has become clogged.)
Chemicals are too cold.
Tank valves not fully open.
Tanks opened in wrong position, allowing only propellant gas to escape.
Blockage in nozzle or Gun Hose Assembly.
Maintain chemical temperature between 75°F and 85°F.
Open tank valves completely by turning counter-clockwise (to tops of tanks).
Tanks valves must me in upright position during use.
Replace nozzle. If this fails to clear the blockage then Gun Hose Assembly must be replaced. Contact your representative.
Foam does not set up properly, or cures brittle and flaky.
Kit is dispensing off ratio. Possible causes are: kinking or blockage of A or B side hose.
After checking that both tank valves are fully open, replace nozzle. Straighten hoses and trigger gun completely into suitable waste receptacle. If this fails then turn off tank valves, dispense any remaining liquid in the hoses, and replace Gun Hose Assembly.
Poor Adhesion
Chemicals are too hot or too cold.
Substrate covered with dirt, oil or foreign matter.
Substrate too hot or too cold.
Maintain chemical temperature between 75 and 85.
Substrate must be clean and completely dry for proper adhesion.
Recommended substrate temperature is 55-95, or spray a thin layer of foam and allow it to cure completely. This will help insulate successive layers.
