Yes, TC Ceramic can be painted over once it has been applied to a concrete surface, but the suitability of doing so depends on the application.

For non-solar applications, painting over TC Ceramic is generally acceptable. You can use any color paint, with an acrylic-type paint being recommended for its durability and ease of application. This option allows you to customize the appearance of the coated surface while still benefiting from the insulating and protective qualities of TC Ceramic.

However, for solar applications—such as on roofs or other exterior surfaces exposed to direct sunlight—it is not recommended to paint over TC Ceramic. Painting in these situations can interfere with the coating’s ability to reflect solar energy and reduce heat absorption, ultimately diminishing its performance benefits in terms of solar reflectance and heat reduction.

In summary, if the primary goal is to maintain optimal solar reflective properties and energy efficiency, it is best to leave the TC Ceramic in its natural state. Conversely, if aesthetic considerations are paramount and the application is not solar-focused, painting over TC Ceramic with a suitable acrylic paint is a viable option.
