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
• 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 3.9 Inch, 2mm board is suited to resin coasters, decoupage coasters, painted coasters, fridge magnets, and small keepsakes.

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 round in shape, 3.9 Inch in size, and 2mm thick.

Q: Is this board good for string art?
A: This board is on the thinner side, so it suits painting, resin, Lippan, and mandala work rather than string art, which needs a thicker 8mm or 12mm board.

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.
