   I want to paint the back side of th 1/4 laun plywood before I put it up and was wondering if it would be better to use an latex exterior primer or exterior paint?

   I assume you're painting the back because it's going to be installed outside.  If not, then there's no reason to paint the back.  For exterior use, backpriming is quite common (in fact, recommended) for all wood trim, soffits, shakes, etc.  Primer will adhere better than paint.  The best latex primers are 100% acrylic. 

   Primer is not as weather-resistant as paint and paint will not adhere properly to old primer (so they say).  Neither of these issues should be of concern when backpriming.

   depends where you are putting it, what for, and why you want to paint it. Generally speaking, luan ply has no business outside, painted or not.

   so Luan's not exterior rated? uh oh. By the way, I saw some fine furniture that was had veneer had attached to plywood and they had to do it to both sides, even though only one was going to show. said if you do something to one side of plywood you have to do it to the other. anyway I go for priming and painting 6 sides. good luck

   Commercial formica countertops, like you see in McD's and other quality eateries, usually has a layer of plain brown laminate on the underside of the tops.  It's there to balance the core so it does not warp.

   Some additional info would be helpfull.

   What finish is on the face.

   Interior or exterior application.

   What will it be installed over, as in, drywall, concrete block, osb, or just studs.

   What is the final use.

   All of the above are major factors that need to be considered.
