Removing strong chemical odors from low-quality or off-gassing paint

DIYers and homeowners purchase cheap or poor-quality paint that emits overwhelming chemical smells, making spaces unusable for days or weeks. Existing solutions like opening windows or waiting are ineffective for strong odors, and people don't know which covering methods (primer, sealant, paint type) actually work to trap the smell. This creates frustration because the paint is already purchased and they need a practical fix without repainting.
