How do artists seal porous stone to prevent staining in animal sculptures?
Artists working with porous stone for animal sculptures often face the challenge of preventing stains and damage. To seal the stone effectively, they typically follow a multi-step process. First, the sculpture is thoroughly cleaned to remove dust and debris. Next, a high-quality stone sealant—such as penetrating sealers or acrylic-based products—is applied evenly across the surface. Multiple thin coats are preferred over a single heavy application. Silane or siloxane-based sealers are popular choices as they penetrate deeply while allowing the stone to breathe. For outdoor sculptures, UV-resistant sealants are essential. Proper sealing not only prevents staining but also enhances the stone's natural colors and protects against weathering. Regular reapplication every few years ensures long-term protection.
