We do not recommend spraying epoxy products because the health and safety risks are enormous. As epoxy leaves a spray gun nozzle, it is reduced to tiny droplets (spray mist). You can easily inhale epoxy that is suspended in the air. It can cause extensive lung damage and other health problems.
The spray mist can settle on your skin, causing sensitization and allergic reactions. It can settle on your eyes, injuring them. Compared to other application methods, spraying increases the amount of hazardous volatile components released from the epoxy. Using solvents to thin the epoxy for spraying adds to the health and safety risks. These hazards are similar to those of any spray painting operation, involving both health and flammability concerns.
If you are determined to spray epoxy, control hazardous vapor and spray mist by using isolation and enclosure, such as a properly designed, ventilated and filtered spray booth. In any case, if you spray epoxy, you must use an air-supplied respirator and full-body protective clothing.
