What are the challenges of painting polyethylene outdoor sculptures without primer?
Painting polyethylene outdoor sculptures without primer presents several challenges. Polyethylene is a non-porous, low-energy plastic, making it difficult for paint to adhere properly. Without a primer, the paint may peel, crack, or blister over time due to temperature fluctuations and UV exposure. Additionally, moisture can seep beneath the paint layer, causing further damage. For long-lasting results, using a specialized primer designed for polyethylene is essential to ensure proper adhesion and durability. Skipping this step often leads to frequent repainting and higher maintenance costs. Understanding these challenges helps artists and conservators achieve better outcomes for outdoor polyethylene artworks.
