I want to laminate two MDF “pre-primed” boards together to make a vertical side panel. I will use Titebond II yellow glue and screws to fasten them together. Since the boards are pre primed with an undercoater, will that have an affect on the glue’s holding power?

I’d recomend calling Titebond’s technical service and get an expert opinion.

generally speaking – yes , as the primer usually seals the material – glue, stain, and finish will have a hard time penetrating it (which is what it’s purpose really is).

but as Joe stated- TB would be able to give you the low down on how much of a problem this would be with TB2

I would think you will want to sand and clean any surface you want to glue. And as Joe suggested call Titebond they are quite helpful I have talked to them.
