What are the best methods for sealing seams in welded polyethylene sculptures?
Sealing seams in welded polyethylene sculptures is crucial for both structural integrity and visual appeal. The best methods include using a hot air welder with polyethylene welding rods, which ensures a strong bond by melting the material evenly. Another effective technique is applying a polyethylene adhesive designed for plastic bonding, followed by sanding for a smooth finish. For larger seams, heat guns with specialized nozzles can help blend the seams seamlessly. Always clean the surface thoroughly before sealing to remove debris or oxidation. Proper sealing not only enhances durability but also preserves the sculpture's artistic quality over time.
