Assembling multi-piece stone sculptures requires strong, durable adhesives to ensure longevity and structural integrity. The most commonly used adhesives include epoxy resin, polyester resin, and specialized stone adhesives. Epoxy resin is favored for its high strength and resistance to environmental factors, making it ideal for outdoor sculptures. Polyester resin, while less robust than epoxy, is cost-effective and suitable for indoor pieces. Additionally, acrylic-based adhesives and polyurethane glues offer flexibility and ease of use for smaller repairs. Choosing the right adhesive depends on factors like stone type, sculpture size, and exposure conditions, ensuring a seamless and lasting bond for your artwork.
