1. Zinsser B-I-N Interior & Spot Exterior Primer
Zinsser B-I-N is a shellac-based primer specifically designed to adhere to stubborn surfaces such as high-gloss paints, varnishes, wood stains, and more. It’s ideal for priming smooth or glossy surfaces that are difficult for most primers to bond to, making it perfect for cabinets, trim, and furniture.
