8" Square Plain Mould

The 8" Square Plain Mould is a clean, flat-base casting mould designed for making resin trays, coasters, wall art panels, and decorative tiles. Its simple square shape gives you a blank canvas to work with pigments, alcohol inks, dried flowers, glitter, and embedments — with a smooth, glossy finish straight out of the mould.

At 8 inches across, this mould strikes a practical balance between desktop size and display impact. It works well with both epoxy resin and UV resin pours, and the flexible material makes demoulding easy without cracking or distorting your finished piece.

• 8-inch square size — ideal for coasters, mini trays, wall panels, and photo resin art
• Plain flat base gives a smooth, mirror-like surface on the finished cast
• Flexible mould walls make popping out cured resin pieces clean and effortless
• Compatible with epoxy resin, UV resin, and polyester resin pours
• Reusable — clean with isopropyl alcohol between pours to extend mould life
• Great for embedding flowers, foils, pigment powders, or personalised prints
• Suitable for hobbyists, home décor makers, and small resin businesses

How to Use

Place the mould on a flat, level surface before pouring. Mix your epoxy resin as per the manufacturer's ratio, add colour or embedments, then pour slowly to avoid bubbles. Use a heat gun or torch to pop surface bubbles. Allow to cure fully before demoulding — typically 24–48 hours for epoxy resin.

Safety Tips

Always work in a well-ventilated area when using epoxy or polyester resin. Wear nitrile gloves and eye protection during mixing and pouring. Keep resin materials away from children and pets. Wash hands thoroughly after handling uncured resin.
