9"x12" Rectangle Plain MDF (4mm)

The 9"x12" Plain MDF Board (4mm) from Shrebhavi is a smooth, flat craft base designed for resin art, acrylic pouring, painting, and mixed-media projects. Cut to a standard A4-adjacent size, it fits easily into frames and display stands, making it a practical choice for hobbyists and small business sellers alike.

Made from 4mm medium-density fibreboard, this board offers a firm, warp-resistant surface that holds epoxy resin and fluid art without bending under the weight. The plain, uncoated face accepts gesso, chalk paint, or a resin seal coat directly, giving you full control over your base preparation.

• Smooth, even surface — minimal sanding needed before applying resin, paint, or gesso
• 4mm thickness — sturdy enough to resist warping during resin pours and heat-gun curing
• Standard 9"x12" size — fits most A4 frames and is easy to ship or package for resale
• Versatile base — suitable for epoxy resin, UV resin, acrylic pouring, decoupage, and tole painting
• Lightweight yet rigid — easy to handle during art-making and safe to hang or display finished pieces
• Clean-cut edges — ready to use straight out of the pack with no rough borders to trim
• Great for small businesses — consistent sizing makes it ideal for creating product lines like trays, wall art, or custom gifts

How to Use

For resin art, seal the MDF surface with a coat of mod podge, gesso, or a thin layer of epoxy before your main pour — this prevents the board from absorbing resin unevenly. For acrylic or paint projects, prime with gesso and let it dry fully before starting. Edges can be painted or taped for a finished look.

Safety Tips

MDF dust can be an irritant — if you sand or cut this board, wear a dust mask and work in a ventilated area. When using with epoxy or UV resin, follow the resin manufacturer's safety guidelines including gloves and ventilation.
