4.5" Flower Coaster Mould

Create beautiful, petal-edged coasters at home with this 4.5" Flower Coaster Mould from Shrebhavi. Made from flexible silicone, the mould releases cured resin cleanly without tearing or distorting the design — no greasing or release spray needed for most epoxy resins.

At 4.5 inches across, it is the ideal size for standard tea and coffee cups, making it a popular choice for hobbyists crafting personalised home décor as well as small businesses producing handmade gifts and custom orders.

• Crisp flower detailing — well-defined petal edges transfer cleanly onto cured resin for a professional finish every time
• Flexible silicone build — pop out your coaster easily once cured; no cracking or sticking even with pigment-heavy pours
• Works with epoxy and UV resin — compatible with two-part epoxy resin, UV resin, and polyester resin
• 4.5" diameter — right-sized for mugs, glasses, and small cups; fits comfortably on most tables and trays
• Reusable and durable — silicone withstands repeated pours without losing shape or surface quality
• Great for layering effects — deep enough to accommodate alcohol ink layers, dried flowers, glitter, and mica pigments
• Beginner friendly — simple to use straight out of the pack; no special tools required

How to Use

Mix your epoxy resin as per the manufacturer's ratio, add pigments or inclusions as desired, and pour slowly into the mould. Tap gently to release air bubbles or use a heat gun briefly. Allow to cure fully (typically 24–48 hours for epoxy) before demoulding. UV resin users can cure under a UV lamp in layers for best results.

Safety Tips

Always wear nitrile gloves and work in a well-ventilated area when handling uncured resin. Keep resin materials away from children and food surfaces. Wash the mould with mild soap and water after use and store flat away from direct sunlight to extend its lifespan.
