Why Choose Zinsser B-I-N Primer for MDF?
MDF’s porous nature often leads to uneven finishes and paint absorption. Zinsser B-I-N’s shellac base fills and seals those fibers quickly, preventing swelling and edge-raising while ensuring a smooth, hard surface for paint or other topcoats. This makes it the best choice for furniture, cabinetry, and crafts where you want impeccable results.
