Square MDF Board | 4x4 Inch | 12mm Thick - String Art & Resin

Square MDF Board 4x4Inch 12mm Thick, Smooth Wooden Base for String Art, Resin Art, and Painting

This square MDF board measures 4x4Inch and is 12mm thick, a smooth, sturdy wooden base made for art and craft. At 12mm thick, this is a strong, rigid board, thick enough to hold nails firmly for string art and to take heavy resin pours and Lippan mirror and clay work without bending. MDF takes acrylic and oil paint, resin, clay, and mirror work beautifully. Both sides are smooth and unfinished, ready for you to sand, prime with gesso, and create.

Key Features

• Shape: Square | Size: 4x4Inch | Thickness: 12mm
• Smooth, unfinished MDF surface on both sides, ready to paint or pour
• Strong and flat, resists warping under paint, resin, and clay
• Thick enough to hold nails firmly for string art and heavy resin pours
• Precision-cut clean edges, a reliable base for detailed work

Where You Can Use This

• String art and thread art (the thickness holds nails firmly)
• Resin art and resin magnets
• Acrylic and oil painting
• Fridge magnets and keepsakes
• Pyrography and wood burning

How to Prepare and Use (Gesso Priming)

• Lightly sand the surface and edges with fine sandpaper, then wipe clean
• Apply 1 to 2 coats of white gesso to prime, this stops the MDF absorbing paint and prevents yellowing
• Let the gesso dry, then sand lightly again for a smooth finish
• Paint, pour resin, or work your design, or hammer in nails for string art
• For resin or chalk paint you can work more directly, though a gesso seal gives the best result

Frequently Asked Questions

Q: What can I make with this MDF board?
A: This 4x4Inch, 12mm board is suited to string art, resin art, painting, magnets, and pyrography.

Q: Do I need to apply gesso before painting?
A: For acrylic and oil paint, yes, prime with white gesso so the board does not absorb the paint and to keep colours vibrant. For resin or chalk paint, a primer is not essential, though gesso sealing helps.

Q: What size and thickness is this board?
A: This board is square in shape, 4x4Inch in size, and 12mm thick.

Q: Is this board good for string art?
A: Yes. At 12mm it is thick enough to hold nails firmly without them poking through the back, ideal for string and thread art.

Q: Is this size good for Lippan or mandala art?
A: This is a small base, best for magnets, coasters, and small resin or painted pieces rather than full Lippan or mandala art, which need a larger board.

Q: Is the board smooth on both sides?
A: Yes. Both sides are smooth and unfinished, so you can paint, pour, or decorate on either face.
