What pigments create colored concrete for vibrant outdoor armchairs?

Colored concrete is a popular choice for creating vibrant and durable outdoor armchairs. The pigments used to achieve these eye-catching hues are typically iron oxide pigments, which come in red, yellow, black, and brown, offering excellent UV resistance and longevity. For brighter colors, synthetic pigments like phthalocyanine blue or green can be mixed with white cement. Another option is acid-based stains, which penetrate the concrete for a translucent, variegated effect. Integral coloring, where pigments are added directly to the concrete mix, ensures consistent color throughout the material. For outdoor furniture, it's crucial to choose high-quality, weather-resistant pigments to maintain vibrancy over time. Proper sealing and finishing further enhance the color and protect the concrete from weathering, making your outdoor armchairs both stylish and long-lasting.
