As seen in the attached images, a piece of wood fell my from my kitchen cupboard, leaving behind a trace of something that looks like a red dried glue. (I don't have much experience with DIY and have no idea what kind of glue this is.)
What do you recommend I should do to glue back the piece? Should I try first to scrape out the red glue? The glue seems to have been very coarsely applied and some areas have noticeable bumps. It also seems very firmly glued to the cupboard.
Moreover, what kind/product of glue do you recommend me to use? I fear that some wood glues wouldn't work in this situation, as the glue has to be applied vertically. Moreover, the bumps of the red glue might make it difficult for the piece to connect back with the cupboard.
