Light sanding of glossy surfaces is necessary to create a mechanical bond for the primer. Its performance lies in its ability to chemically bond with difficult materials while providing an ideal texture for subsequent topcoats to adhere.
Chemical Resistance and Surface Protection with Zinsser Oil Based Primer
Below are the primary materials and situations where this primer excels: Raw, unprimed wood, including plywood and MDF Previously painted surfaces with a glossy sheen Stained wood and cabinetry that cannot be removed Metal substrates prone to rust and oxidation Smoke-damaged walls and surfaces with nicotine stains Bathrooms and kitchens with high moisture exposure Performance Against Stains and Odors One of the most celebrated attributes of this product is its efficacy as a stain blocker.
