Applying oil-based paint directly over an unprepared surface is a recipe for peeling, flaking, and premature failure. Unlike general-purpose primers that are designed for porous surfaces like drywall, bonding primers are formulated to stick to non-porous, glossy finishes.
Bonding Primer vs Regular Primer for Oil Paint: What You Need to Know
A bonding primer for oil based paint is engineered with aggressive resins and sometimes mechanical etching agents that literally grip the slick surface, providing the necessary tooth for the topcoat. A surface prepared with a bonding primer resists chipping and cracking far better than one that has not.
Compatibility with Different Substrates While incredibly effective on wood and metal, the substrate dictates the specific formulation you should choose.
