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

Yes, it is generally recommended to prime before using Rustoleum/Zinsser Co. paint. Priming is important as it promotes better adhesion of the paint to the surface, enhances durability, and helps to achieve a more uniform finish. Primers from Rustoleum/Zinsser Co. are specifically designed to provide optimal performance for their paints. Additionally, priming helps to seal porous surfaces, prevent stains from bleeding through, and can even improve coverage, reducing the number of paint coats required. Skipping the priming step may result in inferior paint adhesion, uneven color, and a shorter lifespan of the painted surface. To ensure the best results with Rustoleum/Zinsser Co. paints, we highly recommend following the priming instructions provided by the manufacturers.
