What you need
Gather a compatible two-part epoxy resin system, a level protected work surface, coaster-sized silicone molds, measuring cups, mixing sticks, resin-compatible pigments, nitrile gloves and eye protection. Follow the resin manufacturer's instructions and safety data sheet. A suitable ventilated work area is essential.
Prepare your workspace and molds
Cover the table, level the molds and remove lint and dust. Decide on your color palette before mixing. Keep food and drink away from the work area.
Measure and mix epoxy
Measure resin and hardener precisely by the manufacturer's specified volume or weight ratio; these are not interchangeable. Stir slowly, scraping sides and bottom, for the recommended time. Never guess the ratio or add extra hardener to speed curing.
Pour and decorate
Pour a thin base layer if the product supports layered pours. Add compatible pigment sparingly and swirl for marble or ocean effects. Avoid exceeding the manufacturer's recommended pigment loading or maximum pour depth.
Cure, demold and finish
Cover the molds against dust and allow the full stated cure time at the recommended temperature. Remove only after the pieces are sufficiently hardened. Smooth sharp edges with suitable protective measures. Do not assume a cured coaster is food-contact safe or heat-resistant: verify the specific resin's certifications and heat rating.
Common problems
Sticky coasters often indicate incorrect ratios, incomplete mixing or low temperatures. Bubbles can result from vigorous stirring. Soft edges may need additional curing time; never sell or use an incompletely cured piece.
Frequently asked questions
How long do resin coasters take to cure?
It depends on the epoxy system, room temperature and pour thickness. Follow the product's demolding and full-cure instructions.
Can resin coasters hold hot cups?
Only within the specific resin's verified heat-resistance limits. Many craft epoxies soften under high heat.
Can I add dried flowers?
Yes, provided the flowers are thoroughly dry and compatible with the resin system.
