Re: Potential Drywall problems in new house
Without seeing the walls for ourselves, there's no way to diagnose the extent of the problem. It sounds like many layers of paint and somewhere along the line an incompatible paint got used which caused the issue you describe. Is the crackling in some areas but not others? Only one room or all?
If it's just crackled paint, then scraping to remove the tall, jagged, and loose material would be in order, followed by applying a layer of drywall topping compound, also known as "floating". It will likely take multiple layers to float the walls smooth, from there you can either texture or paint. Before you paint ALWAYS use a good primer such as Zinsser BullsEye 1.2.3. first, then top coat with paint of choice.
