Epoxy resin coasters are a popular DIY project that can add a touch of elegance and durability to your home decor. They are made by mixing epoxy resin with a hardener and pouring the mixture into a mold, such as a silicone coaster mold. Once cured, the resin forms a strong and glossy surface that can withstand water and heat. Epoxy resin coasters are also easy to clean and maintain, making them a practical choice for daily use. Additionally, they can be customized with various colors and designs, allowing you to create unique and personalized coasters.
