Fiber Reinforced Plastic (FRP) sculptures are widely admired for their durability and versatility. However, to ensure they withstand outdoor elements, making them waterproof is essential. The process begins with selecting high-quality FRP materials, which are inherently resistant to moisture. Next, a gel coat is applied to the sculpture's surface during the molding process. This gel coat acts as a protective barrier, preventing water from penetrating the underlying layers.

After the sculpture is cured, additional waterproofing measures are taken. A waterproof sealant or coating, such as epoxy or polyurethane, is applied to the surface. These coatings not only repel water but also protect against UV rays and environmental wear. For added protection, some artists use multiple layers of sealant, ensuring complete coverage.

Regular maintenance, such as cleaning and reapplying waterproof coatings, further enhances the sculpture's longevity. By combining these techniques, FRP sculptures remain vibrant and intact, even in harsh weather conditions.
