What challenges arise when painting polypropylene-based animal sculptures?
Painting polypropylene-based animal sculptures presents several unique challenges due to the material's non-porous and low-surface-energy nature. One major issue is achieving proper paint adhesion, as polypropylene repels most conventional paints. Surface preparation, such as sanding or using adhesion promoters, is often necessary but time-consuming. Additionally, the paint's durability can be compromised over time, leading to peeling or chipping. Artists must also consider the sculpture's textured details, which may require specialized techniques to ensure even coverage. Overcoming these obstacles requires careful material selection and meticulous execution for a professional finish.
