Spray primer is a preparatory coating applied to surfaces before painting to ensure better adhesion of the paint, enhance durability, and provide a uniform base. It is typically applied using a spray gun or aerosol can, which allows for a smooth, even application, especially on intricate or large surfaces. Spray primers come in various formulations tailored to different materials like wood, metal, and plastic, helping to seal porous surfaces, prevent rust, and block stains. Using a spray primer can significantly improve the final finish of the paint, reducing the likelihood of peeling, chipping, or uneven color. Proper ventilation and protective gear are recommended during application to avoid inhalation of fumes and ensure safety.
