Question tile on greenboard?

I am tiling a tub surround. Because of how things worked out, I have a small strip of to-be-tiled area that is greenboard instead of backerboard. It is going to be covered with trim pieces (2"x6"). Should I prime the greenboard before I put the mastic (and tiles) on or just leave that strip of g.board unprimed? Will the primer affect the adhesion of the mastic - is basically what I'm asking? Thanks for you input.
