how to remove remaining residue from behind removed paneling
Just started one of the many projects to this house built in 1910. Tore out the dropped ceiling and removed old paneling , but we are having a hard time removing the residue from the drywall without gouging it out. Is this even possible? Will a heat gun help? Or is this just a lost cause, and needing to be scim coated? This is only our first project in this house and can use any help we can get.
