How does concrete’s porosity influence paint adhesion for colored sculptures?
The porosity of concrete plays a critical role in paint adhesion for colored sculptures. Highly porous concrete absorbs paint unevenly, leading to patchy coverage and reduced durability. To ensure proper adhesion, the surface must be thoroughly cleaned and sealed before painting. Primers designed for porous materials can help create a uniform base, while acrylic or epoxy-based paints offer better resistance to moisture and wear. Proper sealing techniques, such as using a penetrating sealer, can minimize porosity and enhance paint longevity. Understanding these factors ensures vibrant, long-lasting finishes for concrete sculptures.
