An attachment triggers dispensation of paint through the valve of an inverted aerosol can onto a surface target in response to manipulation of a surveyor's rod or pole. A coupling connects the attachment to the lower end of the surveyor's instrument and a cap seals against the valve end of the inverted aerosol can. A support structure holds the coupling, the inverted aerosol can and the cap together for motion in unison. A nozzle defines a path of pneumatic communication from the valve through the cap. The portion of the cap surrounding the nozzle is resiliently pliable so that, when the nozzle is rested on and the surveyor's instrument is pressed toward the surface target, the resiliently pliable portion of the cap flexes to actuate the valve and dispense paint through the nozzle onto the surface target.
