4" Octagon Shape MDF (4mm)

The 4" Octagon Shape MDF (4mm) from Shrebhavi is a precision-cut craft base ideal for resin art, fluid painting, decoupage, and mixed-media projects. At 4 inches across and 4mm thick, it offers a sturdy, flat surface that holds epoxy resin, acrylic paint, and embellishments without warping under normal working conditions.

Whether you are making resin coasters, decorative wall pieces, or gifting items, this octagon MDF blank gives you a clean, ready-to-use surface with smooth edges. It works equally well for hobbyists experimenting at home and small businesses producing craft products in batches.

• Precise octagon shape: Clean, symmetrical 4-inch cut for consistent results across multiple pieces.
• 4mm thickness: Firm enough to support resin pours without flexing, yet lightweight for wall-hanging or gifting.
• Smooth surface: Minimal sanding needed — ready to prime, paint, or pour resin directly.
• Versatile base: Suitable for epoxy resin art, acrylic pouring, decoupage, pyrography, and mandala painting.
• Coaster-friendly size: 4 inches is a practical size for functional coasters or small decorative display pieces.
• Easy to customise: Can be sealed, primed, spray-painted, or wrapped with resin for a polished finished product.
• Batch-friendly: Uniform shape makes it easy to produce multiple matching pieces for craft fairs or orders.

How to Use

For resin art: seal the MDF surface with a thin layer of Mod Podge or white acrylic paint before pouring epoxy resin. This prevents the wood from absorbing resin unevenly and helps achieve a glossy, bubble-free finish. Allow the sealant to dry fully before starting your pour.

Safety Tips

When working with epoxy resin on this base, use nitrile gloves and work in a well-ventilated area. Keep MDF dust away from eyes and nose if you sand the surface — use a dust mask. Store unused MDF boards flat in a dry place to prevent warping.
