Solder paste consists solder, in the form of tiny spheres, suspended 
in a semi-liquid flux paste. Heating drives off the flux and melts 
the solder onto the copper traces or pads. 

Surface tension of the melted solder will tend to keep it on the 
copper but you'd want to put the paste on the copper fairly 
carefully rather than painting it all over the board. Surface 
tension can only do so much.
