The minimum thickness for decorative concrete will depend on several factors, including the type of decorative finish that you want to achieve and the intended use of the concrete surface. Generally, a minimum thickness of 2 inches (5 cm) is recommended for decorative concrete. However, some decorative techniques may require a thicker application, such as stamped or engraved concrete, which typically requires a thickness of 4 inches (10 cm) or more.
It’s important to note that the thickness of the decorative concrete should also be sufficient to provide the necessary structural support for the intended use of the surface. If the concrete will be subject to heavy loads or foot traffic, it may need to be thicker to ensure its strength and durability.
It’s best to consult with a concrete contractor or decorative concrete specialist to determine the appropriate thickness for your specific project based on the desired finish and intended use.
