Does Behr paint require a primer?

Does Behr paint require a primer? Behr paint does not always require a separate primer, as many Behr products like Behr Premium Plus, Behr Ultra, Behr Marquee, and Behr Dynasty are formulated as paint and primer in one, designed to provide good adhesion and hide over previously painted surfaces in good condition with two coats without separate primer. However, primer is recommended in many situations for best results, such as new drywall, bare wood, masonry, metal, glossy surfaces, drastic color changes from dark to light, and stains, where Behr recommends using Behr primer or Kilz primer, which is sister brand under Masco, for best adhesion and stain blocking. For new drywall, use drywall primer. For bare wood, use wood primer to seal tannin. For best durability and color accuracy, primer helps. So while Behr premium paints are self-priming for repaint, primer is needed for new, bare, stained, or glossy surfaces to ensure adhesion, hide, and long-lasting finish, following label recommendations for specific product.
