Use only water-based materials. Do not use materials which state "FLAMMABLE" on the packaging. For
more information about your material, request MSDS from distributor or retailer.
Spraying certain materials may cause static build-up in the sprayer that can result in static shock to
the user. If this occurs, first ensure the material has a flash point greater than 100° F (38° C) and does not
state that it is FLAMMABLE anywhere on the package. If still feeling a static shock, the material likely con-
tains a non-mineral spirits fluid such as, but not limited to, xylene, toluene, or naphtha, which can build up
static. Switch to an alternative material.
