1. A texture sprayer with remote priming, the texture sprayer comprising:
a main unit, the main unit comprising:
an air compressor configured to compress air;
a sensor that outputs a signal based on a parameter of the compressed air; and
a texture material pump configured to pump texture material, the texture material pump activated to displace the texture material in response to the signal output by the sensor;
a hose assembly comprising:
a first hose configured to fluidly connect to the texture material pump to provide flow of the texture material output by the texture material pump; and
a second hose configured to fluidly connect to the air compressor to provide flow of the compressed air output by the air compressor;
a spray gun configured to attach to the first hose to receive the texture material and to the second hose to receive the compressed air the spray gun comprising:
a nozzle, from which the texture material is forcefully expelled as a spray;
a trigger, configured to cause, when actuated, the spray gun to mix the compressed air with the texture material to forcefully expel the texture material as a spray from the nozzle, wherein such actuation of the trigger causes flow of the compressed air, which is detectable by the sensor to cause activation of the texture material pump, and
a prime valve configured to vent, when open, the compressed air thereby causing flow of the compressed air, which is detectable by the sensor to cause activation of the texture material pump such that the texture material pump drives the texture material to the spray gun while the compressed air is vented prior to the compressed air mixing with the texture material.
