I build period furniture and only use only alcohol based shellac as a finish and quite often spray it due to the fact that I am building big case pieces or pieces with complicated surfaces. I have always done so outside but this is limiting as I need to finish in the winter and at night also. I have a dedicated room off of my basement shop that has a window to the outside. I want to set it up as a spray room but want to do so safely so there is no explosion hazard. It shellac as explosive as lacquer? I know I will need an explosion proof fan. Can I safely use a regular fan with a TEFC motor? I was going to put an opening in the door to this room and leave a window open on the other side for intake air. I would put the light switch on the outside of this room but what about the light fixtures. My idea was to cover them with an enclosure made of Plexiglas. There is no other electricity in this room at all now. Any other hints or precautions. Is this a bad idea? I Don't want to put the house or family at risk. Does anyone else spray shellac in a home shop and how do they go about making it safe? Any ideas would be appreciated.
