Whether you’re applying a fresh coat of paint to your home or vehicle, paint primers and paint sealers are necessary for a polished paint job. Sealers and primers are specially designed to fuse and seal porous materials. This prevents the base surface from bleeding through to the top coat. Whether you are using interior paint or exterior paint, applying paint primer or sealer will cover imperfections, creating a uniform base for your top coat. Additionally, using a sealer or primer reduces the need for multiple top-coat applications and enhances durability. Zoro also offers spray primer for easy application.
