Hi Mark, thank you for your question. These panels can be applied on a slight curved wall but they would need to be secured by further step than required, they would need to be held down with brad nailing them so they can maintain their curvature. Also if the bricks design is the design in mind for the curved wall you would need to install them on a vertical instead of horizontal, this makes it easier for the panel to bend as opposed to posibly over bending the panels on a horizontal and creasing the panels. Hope this helps and if you needed me to send you a couple full size pieces so that you can test them just let me know your address and if it is the bricks design and i'll get them out to you. Thank you again
