Can biodegradable sealants protect concrete sculptures without harming the environment?

Concrete sculptures are durable yet vulnerable to weathering, requiring protective coatings. Traditional sealants often contain harmful chemicals, raising environmental concerns. Biodegradable sealants offer a promising alternative, combining effective protection with eco-friendliness.

These sealants, derived from natural or plant-based polymers, form a protective barrier against moisture, UV rays, and pollutants. Unlike synthetic options, they break down harmlessly over time, reducing environmental impact. Studies show some biodegradable formulas match conventional sealants in durability, making them viable for outdoor art.

However, challenges remain. Their longevity may be shorter, requiring more frequent reapplication. Cost and availability can also be barriers. Despite this, artists and conservators increasingly adopt them, aligning art preservation with sustainability.

In conclusion, biodegradable sealants present a viable, eco-conscious solution for protecting concrete sculptures, though further innovation is needed to optimize performance and accessibility.
