Do I need to prime before using Rustoleum/Zinsser Co. paint?

The decision to prime before using Rustoleum or Zinsser paint depends on various factors, including the surface you are painting, the type of paint you are using, and the desired finish. Rustoleum offers a wide range of products, some of which are designed to be used without a primer, particularly for general painting purposes. However, priming can enhance adhesion and durability, especially on challenging surfaces like metal, plastics, or previously painted areas with gloss finishes. Zinsser, a brand under the Rustoleum umbrella, specializes in primers and sealers. Their products are formulated to provide excellent bonding and can improve the overall appearance of the final coat. If you are painting over a stained or heavily soiled surface, or if you are making a drastic color change, a primer is recommended to ensure even coverage and proper adhesion. If you are uncertain about whether to use a primer, it is best to follow the specific instructions provided on the product label. Furthermore, the Rustoleum website typically offers detailed guidance on their various products, which can be immensely helpful in making the right choice for your project.
