I am finishing a new shower, I used a pre-fab shower enclosure set and would like to tile the walls and ceiling over the shower in the long run. For now though, I'd like to wrap it up. I know I can prime and paint the backerboard but I don't know if this makes it unsuitable for tiling over later. Will I have to add a new layer of backerboard or strip the paint later?

I would suggest against painting the backer board, as I don't see stripping being successful and the magic of backer board relies on a modicum of absorption for adherance and bonding.

thanks,

I dont know if that is right , but it sounded really good!
Id advise not to paint the backer either, i really dont see how that will look very good,
as for the paint causeing problems with the tile being set, id say no. and heres why, we use a spray sealer once we install the backerboard which it is just like a paint , but it is just like haveing a rubber membrane, and the tile sets on that and the backer is totally sealed.
now if the paint you use is laytex or glossy and can see a problem with that, the surface you set the tile on must be stable, that paint cant be peeling or looses in anyway
