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.

Recommended Uses

• Spot priming exterior woodwork—especially knots and sap streaks
• Sealing musty, smoky, or pet-odor-stained areas
• Priming porous surfaces like MDF, plaster, or bare wood
