What is the effect of paint on sprinkler heads?

Sprinkler heads are designed to respond to heat and deliver water through a precise discharge path. Painting a head interferes with both of these functions. The paint can insulate the activation element (such as the heat-sensitive bulb), delaying the heat reaching it and thus delaying release. It can also cover parts of the discharge path, clog the orifice, or alter the spray pattern, which reduces or misdirects the water that should be released. Because of these effects, painting a sprinkler head can prevent proper discharge of water. It does not improve discharge or speed up response; it tends to hinder both.
